SUMMARY

Federal Requirements on Private Health

Insurance Plans

A majority of Americans have private health insurance. Broadly, private health insurance

includes group plans (largely made up of employer-sponsored insurance) and nongroup plans

(i.e., plans a consumer purchases directly from an insurer). Group plans may be fully insured or

self-insured, and fully insured plans may be purchased in the large-group or small-group

markets. (These terms are discussed in the report.)

Private health insurance plans must comply with requirements at both the state and federal levels,

where applicable. Federal requirements for health plans are codified primarily in three statutes:

Title XXVII of the Public Health Service Act (PHSA), Part 7 of the Employee Retirement

Income Security Act of 1974 (ERISA), and Chapter 100 of the Internal Revenue Code (IRC).

Although the health insurance provisions in these statutes are substantively similar, the

differences reflect, in part, the applicability of each statute to different types of private plans. The

PHSA’s provisions apply broadly across private plans, whereas ERISA and the IRC focus

primarily on group plans. The Departments of Health and Human Services (HHS), Labor, and the

Treasury—given their overlapping jurisdiction over private coverage—coordinate enforcement

efforts with respect to these private health insurance requirements.

Federal Requirements on Private Health Insurance Plans

Introduction

A majority of Americans have private health insurance. Private health insurance plans must

comply with requirements at both the state and federal levels, where applicable.

This report organizes and examines selected federal statutory requirements applicable to private

health insurance plans. The first part of this report provides background information about the

types of private health insurance plans and the regulation of such plans. The second part

summarizes selected federal requirements and indicates each requirement’s applicability to one or

more of the following types of private health plans: large group, small group, self-insured, and

nongroup. Table 1 summarizes the applicability of federal statutory requirements across those

plan types. The selected requirements are grouped under the following categories: obtaining

coverage, keeping coverage, health insurance premiums, covered benefits, enrollee cost sharing

and plan payment for benefits, health care provider interactions, enrollee information and appeals,

and federal and public reporting requirements.

Many of the federal requirements described in this report were established under the Patient

Protection and Affordable Care Act (ACA; P.L. 111-148, as amended). However, some were

established under other federal laws. For example, a number of market reforms were first enacted

via the Health Insurance Portability and Accountability Act (HIPAA; P.L. 104-191).1 Certain

private health insurance laws have addressed specific topics, such as mental health parity,2 rather

than a range of market reforms. Recently, the No Surprises Act, part of the Consolidated

Appropriations Act, 2021 (P.L. 116-260), included numerous new private health insurance

requirements, primarily related to surprise billing.3

A companion to this report is CRS Report R47507, Private Health Insurance: A Primer, which

provides further explanations of key concepts related to the provision of health insurance, as well

as enrollment and premium data.

Background

Types of Private Health Insurance Plans

Broadly, private health insurance includes group plans (largely made up of employer-sponsored

insurance) and nongroup plans (i.e., plans a consumer purchases directly from an insurer).

Federal requirements on private health insurance may apply to some or all of several types of

group plans (explained below) and/or to nongroup plans.

1 Some Patient Protection and Affordable Care Act (ACA; P.L. 111-148, as amended) provisions were amendments or

expansions of Health Insurance Portability and Accountability Act (HIPAA; P.L. 104-191) private health insurance

provisions.

2 See, for example, the Paul Wellstone and Pete Domenici Mental Health Parity and Addiction Equity Act of 2008

(P.L. 110-343).

3 Requirements summarized in this report are not grouped according to the laws establishing them. In this report, the

term surprise billing refers to specified situations where an individual is unknowingly, and potentially unavoidably,

treated by a provider outside of the consumer’s health insurance plan network and, as a result, unexpectedly receives a

larger bill than the individual would have received if the provider had been in the plan network. A consumer may be

surprised to receive larger-than-expected medical bills for other reasons; for example, the surprise component may arise

because a consumer misunderstands the terms of his or her health insurance policy and receives a bill for an unexpected

amount. Such other reasons generally are outside the scope of this report and are not included in this report’s usage of

the term surprise billing.

Federal Requirements on Private Health Insurance Plans

Group plans refer to health benefits provided by employers and other entities (e.g., unions,

associations) that sponsor such benefits. These plan sponsors can purchase coverage in the group

market from state-licensed insurers and offer it to their employees (and their employees’

dependents). Health plans obtained this way are referred to as fully insured. The group market is

divided into segments based on size: the small-group market and the large-group market. For

purposes of federal requirements that apply to the group market, states may elect to define small

groups or employers as those with 50 or fewer individuals (e.g., employees) or groups with 100

or fewer individuals. The definition for large group builds on the small-group definition; a large

group has at least 51 individuals or at least 101 individuals, depending on which small-group

definition a given state uses.

Instead of purchasing group plans from insurers, plan sponsors may set aside funds and pay for

health benefits directly; that is, they may self-insure. This alternative approach to providing health

benefits means that such sponsors bear the risk of covering the medical expenses generated by the

individuals covered under the self-insured plan. Groups of any size may self-insure, and federal

requirements on self-insured plans generally do not depend on group size.

The nongroup market, also called the individual market, is where consumers may purchase a

health plan for themselves and their dependents directly from an insurer. For the most part,

nongroup plans are fully insured, and this report discusses them as such.4

Certain Plan Variations

Certain types of group and nongroup plans, and certain other types of private health coverage

arrangements, are regulated differently than the types generally described above. Selected

examples of plan variations are briefly referenced here but otherwise are not included in this

report.

Governmental Employee Plans: Although federal, state, and other governmental employers may

offer group plans as private sector employers do, certain federal requirements on group plans may

apply to governmental plans differently or may not apply.5

Plans Offered by Private Insurers to Enrollees of Public Programs: Some beneficiaries in

public health coverage programs obtain their coverage through commercial insurers contracted by

those programs (e.g., Medicare Advantage or Medicaid managed care plans). Such plans are

subject to those programs’ requirements rather than to those described in this report.

Plans Offered on the Health Insurance Exchanges: The nongroup and small-group markets

include plans sold on and off the health insurance exchanges. The exchanges are government-run

marketplaces that facilitate the purchase of private health insurance plans called qualified health

plans (QHPs). The QHPs must meet all requirements applicable to the nongroup or small-group

market segments, plus additional requirements specific to the exchanges. This report does not

include QHP-specific requirements.6

Exempted Health Coverage Arrangements: Certain types of plans meet a federal definition of

health insurance (i.e., they meet the federal definition of health insurance coverage or group

health plan) but are exempt from compliance with some or all federal health insurance

4 An exception is discussed in the student health insurance coverage section in CRS Report R46003, Applicability of

Federal Requirements to Selected Health Coverage Arrangements.

and the self-insured, nonfederal governmental plans section in CRS Report R46003, Applicability of Federal

Requirements to Selected Health Coverage Arrangements.

requirements that otherwise would apply. Such plans include, for example, grandfathered plans,

excepted benefit plans, and short-term, limited-duration insurance plans.7

Regulation of Private Health Plans

States are the primary regulators of insurers, as codified by the 1945 McCarran-Ferguson Act

(P.L. 79-15).8 Each state requires insurers to be licensed in order to sell health plans in the state,

and each state has a unique set of requirements that apply to insurers and the plans they offer.

Each state’s health insurance requirements are broad in scope and address a variety of issues, and

requirements vary greatly from state to state. State requirements have changed over time in

response to shifting priorities about regulation, the evolving health care landscape, and the

implementation of federal policies.

Health plans offered by state-licensed insurers are subject to state health insurance requirements.

Because self-insured plans are financed directly by the plan sponsor, such plans generally are not

subject to such requirements.

In addition to states, the federal government regulates state-licensed insurers and the plans they

offer. Federal health insurance requirements typically follow the model of federalism: federal law

establishes standards, and states are primarily responsible for monitoring compliance with and

enforcement of those standards. Generally, the federal standards establish a minimum level of

requirements (federal floor) and states may impose additional requirements on insurers and the

plans they offer, provided the state requirements neither conflict with federal law nor prevent the

implementation of federal requirements. For example, the federal “Rating Restrictions”

requirement provides that certain types of health plans may vary premiums by only four factors—

type of coverage (i.e., self-only or family), geographic rating area, tobacco use, and age. Some

states have expanded this requirement by prohibiting issuers from varying premiums by tobacco

use and age, though no states are allowed to permit these types of plans to vary premiums by any

additional factors.

The federal government also regulates self-insured plans, as part of federal oversight of

employment-based benefits. Federal requirements applicable to self-insured plans often are

established in tandem with requirements on fully insured plans and state-licensed issuers.

Nonetheless, fewer federal requirements overall apply to self-insured plans compared with fully

insured plans.

Federal requirements for health plans are codified primarily in three statutes: Title XXVII of the

Public Health Service Act (PHSA), Part 7 of the Employee Retirement Income Security Act of

1974 (ERISA), and Chapter 100 of the Internal Revenue Code (IRC). Although the health

insurance provisions in these statutes are substantively similar, the differences reflect, in part, the

applicability of each statute to different types of private plans. The PHSA’s provisions apply

broadly across private plans, whereas ERISA and the IRC focus primarily on group plans. The

Departments of Health and Human Services (HHS), Labor, and the Treasury—given their

overlapping jurisdiction over private coverage—coordinate enforcement efforts with respect to

these private health insurance requirements.9

Requirements to Selected Health Coverage Arrangements.

Federal Requirements on Private Health Insurance Plans

Federal Requirements

This report focuses on descriptions of statutory private health insurance requirements on major

medical plans and incorporates references to certain regulatory and sub-regulatory activity where

necessary to understand key components of the requirements.10 In general, this report does not

discuss implementation of federal requirements. However, given that Congress recently enacted

surprise billing and transparency requirements and the Secretaries of HHS, Labor, and the

Treasury were in the process of implementing many of those requirements at the time of this

report’s publication, the implementation of recently enacted requirements is discussed, where

appropriate.

For the most part, this report focuses on federal requirements applicable to insurers only, insurers

and self-insured plan sponsors (e.g., employers) in their offering of coverage, and/or on the plans

themselves.11 Selected requirements specific to employers are included to the extent that the

requirements are particularly relevant to the topics discussed in this report (e.g., “COBRA

Continuation Coverage” in the “Keeping Coverage” section).12

The federal requirements described in this report are grouped into the following categories:

obtaining coverage, keeping coverage, health insurance premiums, covered benefits, cost-sharing

limits, requirements related to health care providers, enrollee information and appeals, and federal

and public reporting requirements. Each category of requirements begins with brief, contextual

information about that set of requirements. Some requirements address more than one of these

categories. For example, the requirement “Nondiscrimination Based on Genetic Information”

relates to obtaining coverage, health insurance premiums, and coverage of preexisting

conditions). For the sake of simplicity, these types of crosscutting requirements generally are

discussed only in the most relevant category (in this case, “Obtaining Coverage”).

Federal requirements do not apply uniformly to all types of health plans. For example, plans

offered in the nongroup and small-group markets must comply with the federal requirement to

cover the essential health benefits (EHB; see “Coverage of Essential Health Benefits”); however,

plans offered in the large-group market and self-insured plans do not have to comply with this

requirement. Table 1 lists the specific types of plans to which the federal requirements described

in this report apply: large group, small group, self-insured, and nongroup. Summary descriptions

of the federal requirements follow the table.

federal private health insurance requirements, but the Secretary of the Department of Health and Human Services

(HHS) assumes this responsibility if the Secretary has determined that a state has failed to “substantially enforce” the

federal PHSA provisions. For more information on enforcement of private health insurance requirements, see CRS

Report R46637, Federal Private Health Insurance Market Reforms: Legal Framework and Enforcement.

10 Most people with private health insurance have a major medical plan. Major medical plans provide comprehensive

health benefits compared with limited benefit plans, although the specific covered benefits may vary across major

medical plans. One example of a limited benefit plan is an excepted benefit plan, such as a dental-only or vision-only

plan. For more information on these and other types of plans, see CRS Report R46003, Applicability of Federal

Requirements to Selected Health Coverage Arrangements.

11 In this report, references to plans include applicable group health plans and insurers.

12 This report does not include the full range of federal requirements generally applicable to employee benefit plans,

such as fiduciary requirements. Employee benefit plans include group health plans but also may include other types of

benefits (e.g., retirement plans).

Notes: N.A. indicates the requirement is not applicable to that type of health plan. The requirements listed in

the table do not comprise a comprehensive list of all federal requirements and standards that apply to all health

plans.

a. Some requirements listed in this table also may be found in other sections of the U.S. Code.

b. Health insurance may be provided to a group of people that are drawn together by an employer or other

organization, such as a trade union. Generally, such groups form for a purpose other than obtaining

insurance, such as employment. Insurance provided to a group is referred to as group coverage or group

insurance. With respect to group coverage, the entity that purchases health insurance on behalf of a group is

referred to as the plan sponsor.

c. Consumers who are not associated with a group can obtain health coverage by purchasing it directly from

an insurer in the nongroup (or individual) health insurance market.

d. A fully insured health plan is one in which the plan sponsor purchases health coverage from a state-licensed

insurer; the insurer assumes the risk of paying the medical claims of the sponsor’s enrollees.

e. Self-insured plans refer to health coverage that is provided directly by the organization sponsoring coverage

for its members (e.g., a firm providing health benefits to its employees). Such organizations set aside funds

and pay for health benefits directly. Under self-insurance, the organization bears the risk for covering

medical claims. In general, the size of a self-insured employer does not affect the applicability of federal

requirements.

f.

States may elect to define small groups as groups with 50 or fewer individuals or as groups with 100 or

fewer individuals. The definition for large group builds on the small-group definition; a large group would

have at least 51 individuals or at least 101 individuals, depending on which small-group definition a given

state uses.

g. Employers with fewer than 50 employees are not required to comply with the employer shared

responsibility provisions.

h. Fully insured plans are subject to the nondiscrimination requirement codified at 42 U.S.C. §300gg-16 (and

incorporated by reference into the Employee Retirement Income Security Act of 1974 and the Internal

Revenue Code). Self-insured plans are subject to the nondiscrimination requirement codified at 26 U.S.C.

§105(h). The nondiscrimination requirement for fully insured plans is not in effect as of the date of this

report, but the requirement for self-insured plans is in effect.

i.

COBRA stands for the Consolidated Omnibus Budget Reconciliation Act of 1985 (P.L. 99-272).

j.

Employers with fewer than 20 employees are not required to comply with COBRA’s coverage continuation

requirement.

As part of this requirement, a plan may establish premium discounts or rebates or may modify cost sharing

requirements in return for adherence to a wellness plan. This does not apply to nongroup plans.

Fully insured small-group plans are subject to mental health parity requirements because of the

incorporation of parity requirements into essential health benefit requirements. Self-insured plans

sponsored by small employers (50 or fewer employees) are exempt from mental health parity

requirements.

This requirement applies to employers with 15 or more employees, whether the coverage is fully insured or

self-insured.

Obtaining Coverage

Requirements in this section relate to consumers’ eligibility for coverage.

Guaranteed Issue

Plans must comply with the guaranteed issue requirement.13 In general, plans must accept every

applicant for such coverage, as long as the applicant agrees to the terms and conditions of the

insurance offer (e.g., premium). Plans may restrict enrollment to open and special enrollment

periods under specified circumstances; such circumstances differ between nongroup and group

plans.14 Eligibility for group coverage may depend on meeting a waiting period requirement.15

Plans that otherwise would be required to offer coverage on a guaranteed-issue basis are allowed

to deny coverage to individuals and employers in certain circumstances, such as when a plan

demonstrates that it does not have the network capacity to deliver services to additional enrollees

or the financial capacity to offer additional coverage.

Large-group, small-group, and nongroup plans are subject to this requirement.

Employer Shared Responsibility Provisions

The employer shared responsibility provisions (ESRP), often referred to as the employer

mandate, generally incentivize large employers to offer adequate, affordable health insurance

coverage to their full-time employees and their full-time employees’ dependents.16 If an

13 42 U.S.C. §300gg-1.

14 Nongroup plans that choose to establish an open enrollment period must apply the same period to plans inside and

outside the health insurance exchanges. The open enrollment period rules applicable to exchanges are codified at

45 C.F.R. §155.410. Group plans must allow enrollment during any time of the year, with an exception for small-group

plans. Small-group plans may limit enrollment to an annual period from November 15 through December 15 of each

year if the plan sponsor does not comply with provisions relating to employer-contribution or group-participation rules,

pursuant to state law; see 45 C.F.R. §147.104(b). Qualifying events for special enrollment periods are defined in §603

of the Employee Retirement Income Security Act of 1974 (ERISA; P.L. 93-406) and in 45 C.F.R. §155.420(d).

15 A waiting period refers to an amount of time that must pass before an individual becomes eligible to enroll under the

terms of the plan. A federal requirement specifically concerning the duration of waiting periods is discussed later in this

report (see “Waiting Period Limitation”).

Federal Requirements on Private Health Insurance Plans

applicable large employer fails to offer health insurance or offers substandard coverage to its

employees, the employer may be subject to a penalty.

This requirement applies to employers with 50 or more employees, whether the coverage is fully

insured or self-insured.

Prohibition on Using Health Status for Eligibility Determinations

Plans are prohibited from basing applicant eligibility on health status-related factors.17 Such

factors include health status, medical condition (including both physical and mental illness),

claims experience, receipt of health care, medical history, genetic information, evidence of

insurability (including conditions arising out of acts of domestic violence), disability, and any

other health status-related factor determined appropriate by the HHS Secretary. (A companion

requirement regarding health nondiscrimination applies to premiums; see “Prohibition on Using

Health Status as a Rating Factor,” below.)

Large-group, small-group, self-insured, and nongroup plans are subject to this requirement.

Nondiscrimination Based on Genetic Information

Plans are prohibited from (1) using genetic information to deny coverage, adjust premiums, or

impose a preexisting-condition exclusion; (2) requiring or requesting genetic testing; and (3)

collecting or acquiring genetic information for insurance underwriting purposes.18

Large-group, small-group, self-insured, and nongroup plans are subject to these requirements.

Extension of Dependent Coverage

If a plan offers dependent coverage to children, the plan must make such coverage available to a

child under the age of 26.19 Plans that offer dependent coverage must make coverage available for

both married and unmarried adult children under the age of 26, but plans do not have to make

coverage available to the adult child’s children or spouse (although a plan may voluntarily choose

to cover these individuals).

Large-group, small-group, self-insured, and nongroup plans are subject to this requirement.

Prohibition of Discrimination Based on Salary

The sponsors of health plans (e.g., employers) are prohibited from establishing eligibility criteria

based on any full-time employee’s total hourly or annual salary.20 Eligibility rules are not

permitted to discriminate in favor of higher-wage employees. Additionally, sponsors are

prohibited from providing benefits under a plan that discriminates in favor of higher-wage

employees (i.e., a sponsor must provide all the benefits it provides to higher-wage employees to

all other full-time employees).

Large-group, small-group, and self-insured plans are subject to this requirement.

Federal Requirements on Private Health Insurance Plans

Waiting Period Limitation

Plans are prohibited from establishing waiting periods longer than 90 days.21 A waiting period

refers to the time that must pass before coverage can go into effect for an individual who is

eligible to enroll under the terms of the plan. In general, if an individual can elect coverage that

begins within 90 days of the beginning of the waiting period, the plan complies with this

provision.

Large-group, small-group, and self-insured plans are subject to this requirement.

Keeping Coverage

These requirements relate to consumers’ ability to maintain their coverage once enrolled.

Guaranteed Renewability

Guaranteed renewability is a requirement for plans to renew coverage at the option of the

policyholder or the plan sponsor for nongroup plans and group plans, respectively.22 Plans that

must comply with guaranteed renewability may discontinue the plan only under certain

circumstances. For example, a plan may discontinue coverage if the individual or plan sponsor

fails to pay premiums or if an individual or plan sponsor performs an act that constitutes fraud in

connection with the coverage.

Large-group, small-group, and nongroup plans are subject to this requirement.

Prohibition on Rescissions

Plans generally are prohibited from rescinding coverage; the practice of rescission refers to the

retroactive cancellation of coverage after an enrollee has become sick or injured.23 Plans may

rescind coverage if an enrollee committed fraud or made an intentional misrepresentation of

material fact, as prohibited by the terms of the plan. Such cancellation of coverage requires a plan

to provide at least 30 calendar days’ advance notice to the enrollee.

Large-group, small-group, self-insured, and nongroup plans are subject to this requirement.

COBRA Continuation Coverage24

Certain employers are required to continue to offer coverage to certain employees and their

dependents (qualified beneficiaries) who otherwise would be ineligible for such coverage because

of certain circumstances (qualifying events).25 Generally, plan sponsors must provide access to

continuation coverage to qualified beneficiaries for up to 18 months (or longer, under certain

circumstances) following a qualifying event. Beneficiaries may be charged up to 102% of the

premium for such coverage.

This requirement applies to employers with 20 or more employees, whether the coverage is fully

insured or self-insured.

Federal Requirements on Private Health Insurance Plans

Coverage for Students Who Take a Medically Necessary Leave of Absence

Plans are prohibited from terminating the health coverage of an applicable student who takes a

leave of absence (or other change in educational enrollment) from a postsecondary educational

institution that causes the student to lose student status for health coverage purposes.26 The leave

of absence or change in educational enrollment must be medically necessary and must begin

while the student is suffering from a severe illness or injury. These requirements are colloquially

referred to as Michelle’s Law.27

Large-group, small-group, self-insured, and nongroup plans are subject to this requirement.

Health Insurance Premiums

The following requirements relate to premiums, which are the amounts consumers and others pay

for health coverage.28

Prohibition on Using Health Status as a Rating Factor

Plans are prohibited from varying premiums for similarly situated individuals based on the health

status-related factors of the individuals or their dependents.29 Such factors include health status,

medical condition (including both physical and mental illness), claims experience, receipt of

health care, medical history, genetic information, evidence of insurability (including conditions

arising out of acts of domestic violence), disability, and any other health status-related factor

determined appropriate by the HHS Secretary. (A companion requirement regarding health

nondiscrimination applies to eligibility; see “Prohibition on Using Health Status for Eligibility

Determinations,” above.)

Plans may establish premium discounts or rebates or modify cost-sharing requirements in return

for adherence to a wellness program.30 If a wellness program is made available to all similarly

situated individuals and either does not provide a reward or provides a reward based solely on

participation, then the program complies with federal law without having to satisfy any additional

standards. If a program provides a reward based on an individual meeting a certain standard

relating to a health factor, then the program must meet additional requirements specified in

federal regulations and the reward must be capped at 30% of the cost of employee-only coverage

under the plan. However, the Secretaries of HHS, Labor, and the Treasury have discretion to

increase the reward up to 50% of the cost of coverage if the increase is determined to be

appropriate.

Large-group, small-group, self-insured, and nongroup plans are subject to the overall health

nondiscrimination requirement. Large-group, small-group, and self-insured plans are subject to

the conditions for providing discounts or rebates for wellness activities.

26 42 U.S.C. §300gg–28.

27 P.L. 110-381.

28 For the sake of simplicity, the use of the term premium in this report broadly applies not only to the final amounts

paid by consumers and others for coverage but also the prices for insurance products that health insurance issuers

determine as they develop final premium amounts.

Federal Requirements on Private Health Insurance Plans

Rating Restrictions

Plans must use adjusted (or modified) community rating rules to determine premiums.31 Adjusted

community rating prohibits the use of health factors in the determination of premiums but allows

premium variation based on other factors. Premiums may vary based on the following four

factors:32

•

•

•

•

Type of Enrollment. Plans may vary premiums based on whether only an

individual enrolls in the plan or an individual and dependent(s) enrolls (e.g., selfonly coverage, family coverage).

Geographic Rating Area. Plans may vary premiums based on geographic

location. States are required to establish one or more geographic rating areas

within the state for the purposes of this provision. The rating areas must be based

on one of the following geographic boundaries: (1) counties, (2) three-digit zip

codes, or (3) metropolitan statistical areas (MSAs) and non-MSAs.33

Tobacco Use. Plans may not charge a tobacco user more than 1.5 times the

premium they charge an individual who does not use tobacco.

Age. Plans may not charge an older individual more than three times the

premium they charge a 21-year-old individual. All states must use a uniform age

rating curve to specify the rates across age bands (with exceptions for certain

states).34 For plan years beginning on or after January 1, 2018, plans must use

one age band for all individuals aged 0-14 years, one-year age bands for

individuals aged 15-63 years, and one age band for all individuals aged 64 years

and older.

Small-group and nongroup plans are subject to this requirement.

Rate Review

Under rate review, proposed annual health insurance rate increases that meet or exceed a federal

default threshold are reviewed by a state or the Centers for Medicare & Medicaid Services

31 42 U.S.C. §300gg.

32 Federal law allows states to impose additional rating requirements, provided the state requirements neither conflict

with federal law nor prevent the implementation of federal requirements. For more information about state rating

requirements, see Centers for Medicare & Medicaid Services (CMS), Center for Consumer Information & Insurance

Oversight (CCIIO), “Market Rating Reforms: State Specific Rating Variations,” at https://www.cms.gov/CCIIO/

Programs-and-Initiatives/Health-Insurance-Market-Reforms/state-rating.

33 45 C.F.R. §147.102(b). A three-digit zip code refers to the first three digits of a five-digit zip code. A three-digit zip

code represents a larger geographical area than a five-digit zip code, as all five-digit zip codes that share the same first

three numbers are included in the three-digit zip code.

34 For the federal default and state-specific age rating ratios, see CCIIO, “Market Rating Reforms: State Specific Age

(CMS).35 The federal default threshold is 15%.36 States have the option to apply for state-specific

thresholds.37

Plans subject to review are required to submit to CMS and the relevant state a justification for the

proposed rate increase prior to its implementation, and CMS and the state must publicly disclose

the information. The rate review process does not establish federal authority to deny

implementation of a proposed rate increase; instead, it is a sunshine provision designed to

publicly disclose rate increases that are determined to be unreasonable.

Small-group and nongroup plans are subject to this requirement.38

Single Risk Pool

A risk pool is used to develop premiums for coverage.39 A health insurance issuer must consider

all enrollees in specified plans offered by the issuer to comprise a single risk pool.40 Specifically,

an issuer must include all enrollees in nongroup plans offered by the issuer in a given state in one

risk pool. Similarly, an issuer must include all enrollees in small-group plans offered by the issuer

in a given state in a separate risk pool. (However, states have the option to merge their nongroup

and small-group markets; if a state does so, an issuer will have a single risk pool for all enrollees

in its nongroup and small-group plans.)

Small-group and nongroup plans are subject to this requirement.

Medical Loss Ratio

A medical loss ratio (MLR) is the percentage of a plan’s premium revenue spent on medical

claims (i.e., plan payments toward enrollees’ use of health care covered under the plan).41 The

MLR calculation includes adjustments for quality improvement expenditures, taxes, regulatory

fees, and other factors. Plans are required to report to the HHS Secretary their MLRs with respect

to each plan year. Plans must also meet certain minimum MLR requirements, or otherwise

provide rebates to enrollees.

Nongroup and small-group plans must meet a minimum MLR of 80%; for large groups, the

minimum MLR is 85%. States are permitted to increase the percentages. The HHS Secretary may

lower a state’s percentage for the nongroup market if HHS determines that application of a

minimum MLR of 80% would destabilize that state’s nongroup market.42 Plans whose MLR falls

35 42 U.S.C. §300gg-94. CMS identifies whether states have effective rate review systems. In states with effective rate

review systems, the state conducts review; in states that do not have effective rate review systems, CMS conducts the

review.

37 Any state that wishes to apply a higher threshold than the federal default must submit a proposal for approval to the

HHS Secretary. Since states generally are allowed to enact stricter requirements compared with relevant federal

provisions, states may impose a rate review threshold that is lower than the federal default on their own without

approval from the Secretary. For more information, see CMS, CCIIO, “State-Specific Threshold Proposals,” at

below the specified limit must provide rebates to enrollees on a pro rata basis. Any required

rebates must be paid to enrollees by August of that year.

Large-group, small-group, and nongroup plans are subject to this requirement.

Covered Benefits

These requirements generally relate to benefits that plans cover (including services such as

physician visits, and items such as prescription drugs). Some of these provisions include

mandates to cover certain benefits; others do not mandate coverage but impose requirements

related to certain benefits, to the extent they are covered.

In addition to the requirements discussed in this section, certain provisions discussed elsewhere in

this report also have benefit coverage components (See, e.g., “Prohibition of Discrimination

Based on Salary.”)

Coverage of Essential Health Benefits

Plans must cover a core package of essential health benefits (EHB).43 The benefits that comprise

the EHB generally are not defined in federal law; rather, the law lists 10 broad categories in

which benefits must be covered and tasks the HHS Secretary with further defining the EHB.44

The Secretary’s definition of EHB must at least include the 10 categories and it must conform to

certain limitations and considerations (e.g., it must be equal in scope to the benefits provided

under a “typical employer plan”).45 To date, the HHS Secretary has directed each state to select an

EHB benchmark plan, within certain parameters, to serve as the basis for the state’s EHB.46 The

benchmark plan serves as a reference for applicable plans in that state, which must provide EHB

coverage that is “substantially equal” to such coverage in the benchmark plan, as specified in

regulations.47

Federal regulations have provided specific requirements regarding some EHB categories.48 For

example, current regulation provides that an applicable health plan meets the EHB requirements

for the prescription drugs category of EHB if it covers at least one drug in every U.S.

Pharmacopeia category and class or the same number of prescription drugs in each category and

class as the state-selected EHB benchmark plan.

Cost sharing is possible for most categories of EHB, although certain federal requirements limit

cost sharing on the EHB, as discussed in “Enrollee Cost-Sharing and Plan Payment for Benefits.”

Coverage and cost sharing for EHB services furnished by out-of-network providers may vary.

Federal Requirements on Private Health Insurance Plans

Small-group and nongroup plans are subject to this requirement.

Coverage of Preventive Health Services Without Cost Sharing

Plans are required to cover certain preventive health services (and items) without cost sharing.

This requirement includes, at a minimum, four categories of statutorily required coverage:49

•

•

•

•

Evidence-based items or services recommended with an A or B rating by the U.S.

Preventive Services Task Force (USPSTF);50

Immunizations that have in effect a recommendation by the Advisory Committee

on Immunization Practices (ACIP) of the Centers for Disease Control and

Prevention (CDC), for a given individual;51

Evidence-informed preventive care and screenings for infants, children, and

adolescents, as recommended in guidelines supported by the Health Resources

and Services Administration (HRSA);52 and

Additional preventive care and screenings for women as recommended in

guidelines supported by HRSA.53

If there are changes in recommendations or guidelines in any of these categories (e.g., the

USPSTF announces a new A or B rating), plans generally are required to provide relevant

coverage as of plan years that begin on or after the date that is one year after the change.54

Although cost sharing generally is prohibited for specified preventive benefits, cost sharing for

office visits associated with a furnished preventive benefit may be allowed, as specified in

regulation.55 By regulation, plans generally are not required to cover preventive benefits without

cost sharing if the benefits are furnished out of network.56 Additionally, if a recommended

preventive service does not specify the frequency, method, treatment, or setting for the service,

49 42 U.S.C. §300gg-13; 45 C.F.R. §147.130. The complete list of preventive services required to be covered, per all of

the categories of recommendations, is available at HealthCare.gov, “Preventive Health Services,” at

Federal Requirements on Private Health Insurance Plans

then the plan can determine coverage limitations by relying on “reasonable medical management”

techniques.57

Large-group, small-group, self-insured, and nongroup plans are subject to this requirement.

Coverage of COVID-19 Vaccinations and Other Qualifying Preventive Services

Plans are required to cover Coronavirus Disease 2019 (COVID-19) vaccinations (if not otherwise

covered by the federal government) and vaccine administration fees (even if the vaccines are

federally covered) without consumer cost sharing. This requirement also applies to any

“qualifying coronavirus preventive service,” defined as “an item, service, or immunization that is

intended to prevent or mitigate coronavirus disease 2019” and that is recommended by the

USPSTF or ACIP, as specified.58 This requirement largely mirrors the existing requirement to

cover preventive services without cost sharing, described above. One difference is that this

coverage requirement is effective 15 business days after a relevant USPSTF or ACIP

recommendation.59

Large-group, small-group, self-insured, and nongroup plans are subject to this requirement.

Coverage for Individuals Participating in Approved Clinical Trials

Plans are subject to nondiscrimination and other provisions with respect to qualified individuals’

access to and costs associated with clinical trials.60 Specifically, plans cannot

•

•

•

prohibit qualified individuals from participating in an approved clinical trial;

deny, limit, or place conditions on the coverage of routine patient costs

associated with participation in an approved clinical trial; and

discriminate against qualified individuals on the basis of their participation in

approved clinical trials.61

In short, for a qualified individual participating in an approved clinical trial, a plan must provide

coverage for routine patient costs (all items and services that typically would be covered under

the plan for a qualified individual not enrolled in a clinical trial). Plans may impose consumer

cost-sharing requirements on this coverage. Coverage and cost sharing may vary for clinical trials

offered through an out-of-network provider. The costs of the trial’s “investigational item, device,

or service itself” and other specified costs are not required to be covered by the plan.

Large-group, small-group, self-insured, and nongroup plans are subject to this requirement.

57 45 C.F.R. §147.130(a)(4).

58 42 U.S.C. §300gg-13, Statutory Note, “Rapid Coverage of Preventive Services and Vaccines for Coronavirus.”

59 For additional discussion of this requirement, see CRS Report R46359, COVID-19 and Private Health Insurance

Coverage: Frequently Asked Questions. As that report also discusses, the Coronavirus Disease 2019 (COVID-19)

vaccination coverage requirement is not time-limited, but a separate requirement regarding private health insurance

coverage of COVID-19 testing is limited to the duration of the declared public health emergency. For that reason, the

testing coverage requirement is not otherwise included in this report. There are no federal requirements specific to

private health insurance coverage of COVID-19 treatments, but other requirements may be applicable (e.g., coverage of

the EHB).

60 For purposes of this provision, a qualified individual is an individual who (1) is eligible to participate in an approved

clinical trial for treatment of cancer or other life-threatening disease or condition and (2) has a referring health care

provider who either has concluded that the individual’s participation is appropriate or provides medical and scientific

information establishing that participation in a clinical trial would be appropriate.

Federal Requirements on Private Health Insurance Plans

Coverage of Minimum Hospital Stay After Childbirth

Plans that provide coverage for maternity-related hospital stays generally are prohibited from

restricting coverage for the length of a hospital stay for childbirth for either the mother or the

newborn child to less than 48 hours following vaginal deliveries and to less than 96 hours

following caesarian deliveries.62 In addition, prior authorization requirements for these stays are

prohibited.63 Cost sharing is allowed for maternity-related hospital stays, as long as the cost

sharing for the portions of hospital stays following deliveries is not greater than cost sharing for

preceding portions of such stays.

Large-group, small-group, self-insured, and nongroup plans are subject to this requirement.

Mental Health Parity

Federal parity law does not require plans to cover mental health and substance use disorder

(MH/SUD) benefits when such coverage is not otherwise required by federal or state law.

However, when a plan does cover both MH/SUD benefits and medical/surgical (M/S) benefits,

parity law generally prohibits the imposition of more restrictive limitations on the MH/SUD as

compared with the M/S benefits.64

Specifically, plans are prohibited from imposing more restrictive limits on MH/SUD benefits in

each of the following areas: aggregate lifetime limits and annual limits; financial requirements

(e.g., co-payments); quantitative treatment limitations (e.g., number of days or visits covered);

and nonquantitative treatment limitations, or NQTLs (e.g., preauthorization requirements).

Regulations also have established six classifications of benefits in which parity requirements

apply: (1) in-network inpatient, (2) out-of-network inpatient, (3) in-network outpatient, (4) out-ofnetwork outpatient, (5) emergency care, and (6) prescription drugs.65

In addition, plans are required to disclose certain information to enrollees and others upon

request, including the “criteria for medical necessity determinations” made with respect to

MH/SUD benefits.66

Finally, plans are required to conduct “comparative analyses of the design and application” of

their NQTLs and to make these analyses available to applicable federal and state authorities upon

request.67 The Secretaries of HHS, Labor, and the Treasury must annually request and review at

least 20 of these analyses and follow up on any parity violations identified.

Parity requirements apply to large-group plans, self-insured plans offered by large employers, and

nongroup plans. Primarily by incorporation of parity requirements into EHB requirements, smallgroup plans also are subject to parity law. Self-insured plans offered by small employers are

discharge decisions in consultation with mothers. Plans are prohibited from offering incentives or penalties to providers

or mothers to encourage shorter stays.

63 Some insurers include prior authorization requirements for certain covered benefits. For example, they may require

enrollees to obtain prior authorization from the insurer for routine hospital inpatient care, as a condition for covering

the care.

exempt, and there is also an exemption for plans facing certain increased costs due to parity

implementation.68

Coverage of Reconstruction After Mastectomy

Plans that provide coverage for mastectomies also must cover prosthetic devices and

reconstructive surgery.69 Federal guidance has provided that this coverage requirement is

applicable to female and male enrollees, and the mastectomy does not need to have been

connected to a cancer diagnosis.70 Cost sharing is allowed if consistent with cost sharing for other

covered medical/surgical benefits.

Large-group, small-group, self-insured, and nongroup plans are subject to this requirement.

Coverage of Pregnancy-Related Conditions

Certain employers offering health insurance are required to cover “expenses for pregnancyrelated conditions on the same basis as expenses for other medical conditions” for employees

enrolled in group plans.71 If the group plan offers coverage to employees’ spouses and

dependents, the requirement to cover pregnancy-related services also applies to employees’

spouses (but not necessarily to other dependents) enrolled in the plan.

This requirement applies to employers with 15 or more employees, whether their plans are fully

insured or self-insured.

Prohibition on Coverage Exclusions Based on Preexisting Health Conditions

Plans are prohibited from excluding coverage based on an enrollee’s preexisting health

conditions.72 This requirement does not mandate coverage for any specific benefit, if a plan

otherwise would not cover it. Rather, with respect to the benefits a plan does cover, the plan may

not exclude coverage of those benefits based on health conditions for any enrollee.73 A preexisting

health condition is a medical condition that was present before the date of enrollment for health

68 Although the small employer exemption initially applied to both fully insured and self-insured plans, EHB and parity

regulations have provided that plans subject to EHB requirements (including fully insured plans offered by small

employers) are also subject to parity requirements. Small employers (defined for this purpose as those with 50 or fewer

employees) that self-insure are still exempt from parity requirements. For discussion of these details and the separate

exemption regarding increased costs, see the Department of the Treasury, Department of Labor (DOL), and HHS,

Federal Requirements on Private Health Insurance Plans

coverage, whether or not any medical advice, diagnosis, care, or treatment was recommended or

received before such date.

Large-group, small-group, self-insured, and nongroup plans are subject to this requirement.

Enrollee Cost Sharing and Plan Payment for Benefits

As enrollees receive benefits covered by a plan, the costs for those benefits are paid by the

enrollee and/or by the plan, depending on the plan’s terms. In addition to setting premiums and

determining covered benefits, plans set enrollees’ cost-sharing levels. Enrollee cost sharing, also

called out-of-pocket (OOP) costs, generally includes deductibles, coinsurance, and co-payments,

up to annual OOP limits.74 The terms of the plan also specify the amounts the plan will pay

providers for covered benefits.

The following requirements relate to enrollee cost sharing and/or the costs of the benefits that the

plans cover. They all reference the “Coverage of Essential Health Benefits” requirement

discussed in the prior section. Certain provisions discussed elsewhere in this report are also

relevant to other aspects of cost sharing or plan payments to providers, such as those relating to

out-of-network providers in “Health Care Provider Interactions.”

Maximum Annual Limitation on Cost Sharing

Plans must have annual limits on enrollee OOP costs that are no higher than federally set

amounts.75 In other words, once an enrollee’s OOP spending has met the federal annual limit (or a

plan’s own annual limit, if lower), the plan generally will pay 100% of covered applicable costs

for the remainder of the plan year.

HHS adjusts the limits each year through rulemaking and/or guidance using calculations required

by the ACA.76 In 2025, the limits cannot exceed $9,200 for self-only coverage and $18,400 for

coverage other than self-only.77 If a consumer is solely enrolled in a plan, the self-only limit

applies. If a consumer and one or more dependents are enrolled in a plan, both types of limits

apply.78

74 In general, beginning with each plan year, an enrollee pays 100% of costs for covered health care benefits until the

costs meet a certain threshold amount, called a deductible. Exceptions apply. After reaching the deductible, the enrollee

pays coinsurance (a percentage amount) or co-payments (a flat amount) for covered benefits and the plan pays the rest.

If an enrollee’s spending meets an annual out-of-pocket limit, the plan generally will pay 100% of covered costs for the

remainder of the plan year.

75 42 U.S.C. §300gg-6 and 18022.

76 See, for example, CMS, CCIIO, “Premium Adjustment Percentage, Maximum Annual Limitation on Cost Sharing,

Reduced Maximum Annual Limitation on Cost Sharing, and Required Contribution Percentage for the 2025 Benefit

Year,” November 15, 2023, at https://www.cms.gov/files/document/2025-papi-parameters-guidance-2023-11-15.pdf.

77 See CRS Report R44065, Overview of Health Insurance Exchanges for these and prior year annual limits.

78 For example, for a family of three enrolled in a plan with the 2025 limits: Once individual 1 incurs $9,200 in cost

sharing for his or her benefits as specified above (generally, on in-network EHB), the plan is responsible for 100% of

the costs for such benefits for the rest of the plan year. However, if individuals 2 and 3 have incurred only $2,000 each

in cost sharing, they would still be responsible for cost sharing at that time. If any combination of the enrollees’ cost

sharing adds up to $18,400, then the plan would be responsible for 100% of all of the enrollees’ costs for covered

benefits for the rest of the plan year. For additional information about the annual OOP limit, see CMS, CCIIO,

Congressional Research Service

19

Federal Requirements on Private Health Insurance Plans

The limits generally apply only to in-network coverage of the EHB.79 However, certain

exceptions may apply.80

Large-group, small-group, self-insured, and nongroup plans are subject to this requirement.81

Minimum Actuarial Value Requirements

Plans must pay for covered benefits in compliance with minimum actuarial value (AV) standards.

AV estimates the “percentage of total average costs for covered benefits” to be paid by a plan.82 A

plan’s AV must comply with one of four levels corresponding with a precious metal designation

(i.e., platinum, gold, silver, or bronze).83 The four AV levels are 90% for platinum, 80% for gold,

70% for silver, and 60% for bronze.84

Given that plans and enrollees collectively pay total costs, AV is the plan counterpart to enrollee

cost-sharing expenses. The higher the AV percentage, the lower the cost sharing, on average. For

example, a silver plan expects to cover approximately 70% of total costs for covered benefits.

Because enrollees’ use of such benefits vary, a given enrollee’s actual cost sharing may be more

or less than 30% of costs associated with receipt of covered benefits. AV is not a measure of plan

generosity for an enrolled individual or family, nor is it a measure of premiums or benefits

packages.

AV calculations include only costs associated with a plan’s covered EHB that are furnished by innetwork providers, unless otherwise addressed in federal or state law.85

Small-group and nongroup plans are subject to this requirement.

Prohibition on Lifetime and Annual Coverage Limits

Plans are prohibited from setting lifetime or annual dollar limits on their coverage of the EHB,

generally whether provided in-network or out-of-network.86 In other words, plans may not limit

their spending for such benefits for any enrollee, either during the entire period an individual is

enrolled in the plan (lifetime coverage limits) or during a plan year (annual coverage limits).

Plans are permitted to place lifetime and annual coverage limits on covered benefits that are not

considered EHBs, to the extent that federal and state law otherwise permit such limits.

45 C.F.R. §156.130. Also see HHS, DOL, and Treasury, “Affordable Care Act Implementation FAQs – Set 18,”

January 9, 2014, at https://www.cms.gov/CCIIO/Resources/Fact-Sheets-and-FAQs/aca_implementation_faqs18,

80 See, for example, “Preventing Surprise Medical and Air Ambulance Bills.” Also see 45 C.F.R. §156.130(h)

regarding prescription drug coupons.

81 This requirement applies to EHB coverage, and large-group and self-insured plans are not required to cover the EHB.

The Tri-Agency FAQ 18, question 2, provides that such plans must use a permissible definition of EHB (including any

state-selected EHB benchmark plan) to determine whether they comply with this requirement. This is consistent with

regulations implementing the separate “Prohibition on Lifetime and Annual Coverage Limits”.

Federal Requirements on Private Health Insurance Plans

Large-group, small-group, self-insured, and nongroup plans are subject to this requirement.87

Health Care Provider Interactions

These requirements relate to plan interactions and consumer interactions with providers,

including in the context of plan coverage and benefits for services furnished to enrollees by

certain out-of-network providers.

Certain requirements discussed in this section relate to provisions discussed elsewhere in this

report. (See, e.g., the relationship between “Provider Directory Requirements” and “Services

Provided Based on Incorrect Provider Directory Information.”)

Preventing Surprise Medical and Air Ambulance Bills

Plans are required to limit consumer cost sharing and to pay providers a specified amount when

enrollees receive certain out-of-network medical care:88

•

•

•

Out-of-network emergency services (if the plan covers services in an emergency

department of a hospital or an independent freestanding emergency department)

Nonemergency services provided by an out-of-network provider at an in-network

facility (when notice and consent requirements have not been satisfied)89

Out-of-network air ambulance services

When applicable, the cost-sharing requirement for these services cannot be greater than the cost

sharing that would have applied for the service had it been provided by an in-network provider.90

Generally, plans are required to calculate cost-sharing amounts based on the lesser of the billed

charge for the service or the plan’s median in-network rate for the service.91 Any cost-sharing

amounts paid by enrollees must be counted toward any in-network deductibles and in-network

OOP maximums.

The amount a plan is required to pay a provider for these out-of-network services is determined

according to a federal payment methodology.92 Under this methodology, the plan must make an

initial payment (or notice of denial of payment) to the out-of-network provider for services

rendered, after which the parties may negotiate to reach an agreed-upon payment amount. If

negotiations are unsuccessful, the parties may use an independent dispute resolution process,

wherein an arbitrator determines the final payment amount. However, if a state has its own

87 This requirement applies to EHB coverage, and large-group and self-insured plans are not required to cover the EHB.

Regulations provide that such plans must use a permissible definition of EHB (including any state-selected EHB

benchmark plan) to determine whether they comply with this requirement. See 45 C.F.R. §147.126(c).

88 42 U.S.C. §§300gg-111 and 300gg-112. For more information on the topic of surprise billing, including these federal

requirements, see CRS Report R46856, Surprise Billing in Private Health Insurance: Overview of Federal Consumer

Protections and Payment for Out-of-Network Services.

89 For notice and consent requirements, see 42 U.S.C. §300gg-132(d).

90 With covered, out-of-network air ambulance services specifically, the cost-sharing requirement must be the same as

the cost sharing for an in-network provider.

91 For applicable emergency services and covered nonemergency services provided by an out-of-network provider at an

in-network facility, if the service is provided in a state that has an applicable surprise billing law or an all-payer model

agreement, the cost-sharing amount is to be calculated in accordance with such law or agreement. See definition of

recognized amount at 45 C.F.R. §149.30, as referenced by 45 C.F.R §149.110(b)(3)(iii). For air ambulance services,

see 45 C.F.R. §149.130(b)(2).

Federal Requirements on Private Health Insurance Plans

surprise billing law that pertains to a given plan type, provider type, and service, the state law

methodology would apply. In addition, if a state has an all-payer model agreement, the amount

designated under the agreement would apply.

In addition to the requirements above regarding out-of-network emergency benefits, plans must

comply with additional requirements relating to benefits for emergency services.93 If a plan

covers services in an emergency department of a hospital or emergency services in an

independent freestanding emergency department, the plan is required to cover those services

without the need for any prior authorization, without coverage limitations or requirements for outof-network providers and facilities that are more restrictive than the limitations or requirements

that apply to in-network emergency providers and facilities, and regardless of any other term or

condition of the plan (with limited exceptions).

Large-group, small-group, self-insured, and nongroup plans are subject to this requirement.

Continuity of Care

Plans are required to satisfy certain requirements when continuing care patients receive services

from a provider that initially was in network but subsequently became out of network during the

course of treatment (i.e., as a result of the termination of the contractual relationship between the

plan and provider).94 In these situations, plans must

•

•

•

notify the continuing care patient of the termination and the enrollee’s right to

elect continued transitional care from the now-out-of-network provider;

provide the continuing care patient with an opportunity to notify the plan of his

or her need for transitional care; and

permit the continuing care patient to continue his or her course of treatment from

the now out-of-network provider for, at most, 90 days and under the same terms

and conditions as applied when the provider was in network.

Large-group, small-group, self-insured, and nongroup plans are subject to this requirement.

Services Provided Based on Incorrect Provider Directory Information

Plans must limit consumer cost sharing for covered, out-of-network services provided to enrollees

who relied on incorrect provider network information.95 If an enrollee receives a covered service

from an out-of-network provider that the enrollee thought was in network due to incorrect

information from the plan, the cost-sharing requirement cannot be greater than the cost sharing

that would have applied had the service been provided by an in-network provider. In addition,

plans must count any of these out-of-network cost-sharing amounts toward any in-network

deductibles and in-network OOP maximums.

Large-group, small-group, self-insured, and nongroup plans are subject to this requirement.

93 42 U.S.C. §300gg-111(a)(1).

94 42 U.S.C. §300gg-113. For purposes of this provision, a continuing care patient is an individual who satisfies one of

the following criteria: (1) is undergoing treatment for a serious and complex condition; (2) is undergoing institutional

or inpatient care; (3) is scheduled to undergo nonelective surgery; (4) is pregnant and undergoing a course of treatment

for the pregnancy; or (5) is or was determined to be terminally ill and is receiving treatment for such illness.

Federal Requirements on Private Health Insurance Plans

Choice of Health Care Professionals

Plans are subject to three requirements relating to the choice of health care professionals.96 First,

plans that require or allow an enrollee to designate a participating primary care provider are

required to permit the designation of any participating primary care provider who is available to

accept the individual. Second, plans that require or allow an enrollee to designate a participating

primary care provider for an enrolled child are required to permit the designation of a

participating physician who specializes in pediatrics as the child’s primary care provider. Third,

plans that provide coverage for obstetrical or gynecological care cannot require authorization or

referral by the plan or any person (including a primary care provider) for a female enrollee who

seeks obstetrical or gynecological care from an in-network health care professional who

specializes in obstetrics or gynecology.

Large-group, small-group, self-insured, and nongroup plans are subject to this requirement.

Nondiscrimination Regarding Health Care Providers

Plans may not discriminate, with respect to participation under the plan, against any health care

provider that is acting within the scope of that provider’s license or certification under applicable

state law.97 Federal law does not require that a plan contract with any health care provider willing

to abide by the plan’s terms and conditions, and it also does not prevent a plan or the HHS

Secretary from establishing varying reimbursement rates for providers based on quality or

performance measures.

Large-group, small-group, self-insured, and nongroup plans are subject to this requirement.

Prohibition on Gag Clauses on Price and Quality Information

Plans are prohibited from entering into agreements with providers and other selected entities that

would directly or indirectly prevent the plan from

•

•

•

disclosing provider-specific cost or quality of care information to referring

providers, enrollees, plan sponsors, or individuals eligible to enroll in the plan;

electronically accessing de-identified claims and encounter data for each

enrollee;98 and

sharing such information with a business associate, consistent with applicable

privacy regulations.99

Plans are required to annually attest to the Departments of HHS, Labor, and the Treasury that the

plans are in compliance with this requirement.

Large-group, small-group, self-insured, and nongroup plans are subject to this requirement.

Enrollee Information and Appeals

Requirements in this section relate to plan disclosure of certain information to enrollees (and

applicants, as specified) and to enrollees’ rights regarding appeals of coverage denials.

96 42 U.S.C. §300gg-117.

23

Federal Requirements on Private Health Insurance Plans

In addition to the requirements discussed below, certain provisions discussed elsewhere in this

report also have enrollee information and appeals components (see, e.g., “Mental Health Parity”).

Summary of Benefits and Coverage and Uniform Glossary

Plans are required to provide a summary of benefits and coverage (SBC) to individuals at the time

of application, by the first day of coverage (if there are changes since the time of application),

prior to the time of renewal, and otherwise upon request.100 The SBC must meet certain

requirements with respect to the included content and the presentation of the content (e.g., it must

include uniform definitions of health insurance terms and a description of the coverage and cost

sharing for specified categories of benefits). Plans may provide the SBC in paper or electronic

form. Plans must notify enrollees of any material modifications (e.g., changes in benefits) no later

than 60 days prior to the date that the modifications would go into effect.

Plans also must provide a uniform glossary of terms commonly used in health insurance coverage

(e.g., coinsurance) to enrollees upon request.

Large-group, small-group, self-insured, and nongroup plans are subject to these requirements.

Advanced Explanation of Benefits

When an enrollee schedules to receive medical care from a provider and seeks to have the care

covered by a plan, providers are required to provide a good-faith estimate of expected charges for

such care to the enrollee’s plan.101 Upon receipt of this estimate, plans are required to develop a

notification, referred to as an advance explanation of benefits, and provide it to the enrollee

within designated timeframes.102 The advance explanation of benefits must contain specified

pieces of information, including the provider’s network status, the provider’s good-faith estimate

of expected charges, the plan’s estimated payment toward the expected charges, the enrollee’s

estimated cost sharing, an estimate of the amounts accumulated toward the enrollee’s deductible

and OOP limit, whether the scheduled care is subject to a medical management technique,103 and

a disclaimer that the information in the advance explanation of benefits comprises estimates that

are subject to change.

Large-group, small-group, self-insured, and nongroup plans are subject to this requirement. The

Departments of HHS, Labor, and the Treasury have deferred enforcement of this requirement

until the departments undertake notice and comment rulemaking.104 As of the date of this report,

regulations have not been issued.

100 42 U.S.C. §300gg-15; 45 C.F.R. §147.200. In addition, there is a separate requirement on group plans to provide a

Summary Plan Description (SPD) to enrollees. SPD requirements are applicable to employee benefit plans, which

includes group health plans but also may include other types of benefits (e.g., retirement plans). In general, this CRS

report focuses on requirements specific to health insurance and group health plans. For information about SPD and

other disclosure requirements on employee benefit plans, including certain additional disclosure requirements for group

Federal Requirements on Private Health Insurance Plans

Plan Identification Card Information

Plans are required to include the following on any physical or electronic enrollee plan

identification cards: any deductible applicable to the plan, any OOP maximum limitation

applicable to the plan, and a consumer assistance telephone number and website.105

Large-group, small-group, self-insured, and nongroup plans are subject to this requirement.

Price Comparison Tool

Plans are required to disclose certain price comparison information to enrollees through a selfservice tool on a website; by telephone; and, upon request, in paper.106 Price comparison

information includes but is not limited to an estimate of the enrollee’s cost sharing for covered

items and services by billing code or descriptive term, amounts accumulated, in-network rates,

and out-of-network allowed amounts.107

Large-group, small-group, self-insured, and nongroup plans are subject to this requirement.

Provider Directory Requirements

Plans are required to establish and adhere to certain provider directory standards.108 These

standards require plans to establish a public, online database that contains provider directory

information for each provider with which they have a direct or indirect relationship. The

standards also require plans to establish a process to verify and update this information at least

once every 90 days. In addition, they require plans to establish a protocol to respond to enrollees

who request information (via phone or electronically) about a provider’s network status. Federal

law also requires that print directories include language indicating the date on which the

information was accurate and noting that enrollees should consult the online database or the plan

to obtain the most current provider directory information.

Large-group, small-group, self-insured, and nongroup plans are subject to this requirement.

Disclosure of Patient Protections Against Balance Billing

Plans are required to disclose information on federal surprise billing requirements;109 applicable

state requirements addressing out-of-network provider charges, where appropriate; and the

appropriate state and federal agencies that an individual can contact if a provider is believed to

109 More specifically, the requirements on plans at 42 U.S.C. §300gg-111 and the requirements on providers prohibiting

balance billing in certain circumstances at 42 U.S.C. §§300gg-131 and 300gg-132. The term balance billing, which is

one type of surprise bill, refers to amounts that an out-of-network provider can charge a consumer for care that is in

addition to the amount the consumer pays in out-of-network cost sharing and the amounts that the provider receives

from a plan for such services. For more information on the relationship between surprise bills and balance bills, see the

“Private Health Insurance Billing Overview” in CRS Report R46856, Surprise Billing in Private Health Insurance:

have violated such requirements.110 This information must be made publicly available, posted on

a public website of the plan, and included on each explanation of benefits for out-of-network

emergency services and covered, nonemergency services provided by an out-of-network provider

at an in-network facility.

Large-group, small-group, self-insured, and nongroup plans are subject to this requirement.

Information on Prescription Drugs

Plans (including the pharmacy benefit managers contracted with them) are prohibited from

restricting pharmacies from informing health plan enrollees of the difference in OOP costs they

would pay for a prescription drug using their health plan coverage versus going “outside” of their

health plan benefit to purchase a prescription drug.111 Stated another way, this requirement aims

to end what some refer to as gag clauses in contracts between pharmacies and plans or pharmacy

benefit managers and to allow pharmacies to inform health plan enrollees if it would be less

expensive for them to obtain their prescription without using their health plan benefit.112

Large-group, small-group, self-insured, and nongroup plans are subject to this requirement.

Disclosure to Enrollees of Individual Market Coverage

Plans are required to disclose to enrollees any direct or indirect compensation provided to agents

or brokers associated with enrolling individuals in such coverage.113 Plans must make this

disclosure prior to an individual finalizing a plan selection and must include the disclosure on any

documentation confirming the individual’s enrollment. The plan also must annually report similar

information to HHS.

Nongroup plans are subject to this requirement.

Appeals Process and External Review

Plans must implement an effective appeals process for coverage determinations and claims.114 At

a minimum, plans must

•

•

Federal Requirements on Private Health Insurance Plans

Plans also must implement either a state or a federal external review process for coverage

determinations and claims.115

Large-group, small-group, self-insured, and nongroup plans are subject to this requirement.

Federal and Public Reporting Requirements

The following requirements relate to the reporting of specified information to the federal

government and/or the public disclosure of certain information.

In addition to the requirements discussed in this section, certain provisions discussed elsewhere in

this report also have federal and public reporting requirement components (see, e.g., “Mental

Health Parity”).

Reporting Requirements Regarding Quality of Care

The HHS Secretary was required to develop quality reporting requirements for use by specified

plans, concluding no later than two years after enactment of the ACA.116 The Secretary also was

required to publish regulations governing acceptable provider reimbursement structures not later

than two years after ACA enactment. No later than 180 days after these regulations were

promulgated, the U.S. Government Accountability Office was required to conduct a study

regarding the impact of these activities on the quality and cost of health care. To date, the HHS

Secretary has not published the required final regulations.

However, the Department of Labor’s (DOL’s) Employee Benefits Security Administration

published a proposed rule on July 21, 2016, that would modify current annual reporting

requirements for pension and other employee benefit plans under ERISA Titles I and IV.117 Under

these modified requirements, plans would report on the financial condition and operations of the

plan, among other things, using standardized forms (Form 5500 Annual Return/Report or the

Form 5500-SF). This rule proposes that a group health plan subject to ERISA that complies with

these reporting requirements would satisfy the quality reporting requirements in PHSA Section

2717, as incorporated in ERISA. To date, this proposal has not been finalized through

rulemaking.

Once the reporting requirements are implemented, plans would submit annually, to the HHS

Secretary (and to DOL and the Department of the Treasury) and to enrollees, a report addressing

whether plan benefits and reimbursement structures do the following:

•

•

•

Improve health outcomes through the use of quality reporting, case management,

care coordination, and chronic disease management

Implement activities to prevent hospital readmissions, improve patient safety, and

reduce medical errors

Implement wellness and health-promotion activities118

115 42 U.S.C. §300gg-19(b).

116 42 U.S.C. §300gg-17.

117 DOL, Employee Benefits Security Administration, “Annual Reporting and Disclosure,” Proposed Rule, 81 Federal

Register 47495, July 21, 2016.

118 Wellness and health-promotion activities include personalized wellness and prevention services, specifically efforts

related to smoking cessation, weight management, stress management, physical fitness, nutrition, heart disease

prevention, healthy lifestyle support, and diabetes prevention. These services may be made available by entities (e.g.,

health care providers) that conduct health risk assessments or provide ongoing face-to-face, telephonic, or web-based

intervention efforts for program participants.

Large-group, small-group, self-insured, and nongroup plans are subject to this requirement.

Reporting Requirements Regarding Air Ambulances

HHS, in consultation with the Department of Transportation, was required to issue rulemaking no

later than one year after enactment of the No Surprises Act indicating how plans should submit

specified air ambulance information to the federal government.119 A proposed rule regarding this

requirement was published on September 16, 2021, but a final rule had not been published as of

the date of this report.120

Once the final rule is promulgated, plans would be required to report air ambulance claims data

and other specified information regarding air ambulance providers to the federal government for

two consecutive plan years.121

HHS, in consultation with the Department of Transportation, is required to summarize the

information submitted by plans to develop a report that is made available to the public.122

Large-group, small-group, self-insured, and nongroup plans are subject to this requirement.

Reporting Requirements Regarding Pharmacy Benefits and Drug Costs

Plans are required to annually submit specified information on prescription drug and total health

care spending to HHS, DOL, and Treasury.123 This information includes, but is not limited to, the

plan’s 50 brand prescription drugs most frequently dispensed by pharmacies; the plan’s 50 most

costly prescription drugs by total annual spending; the plan’s 50 prescription drugs with the

greatest increase in plan spending; total health care spending broken down by specified

categories; and the impacts of rebates, fees, and other remuneration paid by drug manufactures to

the plan (or its administrators or service providers) on plan premiums and cost-sharing.124

HHS, DOL, and Treasury are required to biannually issue a public, online report on prescription

drug reimbursements, prescription drug pricing trends, and the role of prescription drug costs in

contributing to premium increases or decreases.

Large-group, small-group, self-insured, and nongroup plans are subject to this requirement.

in-network rates with providers for all covered services and items (except

prescription drugs that are subject to a fee-for-service reimbursement

arrangement),

out-of-network allowed amounts and billed charges for covered services and

items during a specific time period, and

negotiated rates and historical net prices for covered prescription drugs.

Plans are currently posting in-network rate and out-of-network allowed amount files. The

Departments intend to develop an implementation timeline for the prescription drug machinereadable file, which had yet to be developed by the date of this report.126

Large-group, small-group, self-insured, and nongroup plans are subject to this requirement.
