Surprise Billing: Independent Dispute Resolution Process
This In Focus summarizes statute and interim final rule
(IFR) regulations to describe the independent dispute
resolution (IDR) process available to insurers and out-ofnetwork providers in certain surprise medical billing
situations. It accounts for IFR aspects invalidated in the
Texas Medical Association v. U.S. Department of Health
and Human Services decision but predates a federal
response to that decision.
For more information on surprise billing in general and
corresponding consumer protections, see CRS Report

Overview of Federal Consumer Protections and Payment
for Out-of-Network Services. For more information on the
litigation related to the IDR process, see CRS Insight

Resolution Process and Related Litigation.

Surprise Billing
In general, surprise billing occurs when consumers are
unknowingly, and potentially unavoidably, treated by
providers outside of their health insurance plan’s network.
As a result, these consumers unexpectedly receive larger
bills than they would have received had the provider been
in their plan’s network. To address surprise billing,
Congress passed the No Surprises Act, which was part of
the Consolidated Appropriations Act, 2021 (P.L. 116-260).
Among other requirements, the No Surprises Act specified
a methodology to determine the amount insurers must pay
to providers for services provided in the following surprise
billing situations: out-of-network emergency services,
nonemergency services provided by an out-of-network
provider at an in-network facility, and out-of-network air
ambulance services. (For post-stabilization services [in
limited circumstances] and out-of-network nonemergency,
non-ancillary services provided at an in-network facility,
the federal methodology would not apply if notice and
consent requirements were satisfied.) The amount an
insurer pays, when combined with amounts consumers pay
in cost sharing, represents the total amount a provider
receives as payment for services.

Methodology to Determine Insurer
Payment to Providers
Under the federal methodology, insurers must make an
initial payment (or notice of denial of payment) to the
provider, after which the provider or the insurer may initiate
open negotiations to determine an agreed-upon payment
amount for the services. If negotiations are unsuccessful,
the parties may use an IDR process, which is a “baseballstyle” arbitration process.

This methodology does not apply in all situations. If a state
has its own 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.
Initial Payment
Insurers are required to make an initial payment (or notice
of denial of payment) to a provider within 30 calendar days
of receiving a bill for services. Federal law and regulations
do not specify how to determine the amount of the initial
payment, though it should be an amount that the insurer
intends to be payment in full (i.e., not a first installment).
Open Negotiation
After the insurer makes an initial payment (or notice of
denial of payment), the provider or the insurer may initiate
open negotiations during the subsequent 30-business-day
period by providing a notice to the other party. The parties
then have 30 business days from the date the notice was
sent (i.e., the open negotiation period) to reach an
agreement on the payment amount. If the negotiations are
successful, the insurer is required to pay to the provider the
agreed-upon amount (or, after accounting for the initial
payment, any remaining balance) within 30 calendar days.
Independent Dispute Resolution Process
If a provider and insurer cannot reach an agreement during
the open negotiation period, then either party may initiate
the IDR process. The IDR process is a baseball-style
arbitration process under which the provider and the insurer
each submit to a neutral, certified third-party arbitrator (i.e.,
IDR entity) their best and final offers that represent the
amount that each party considers adequate payment. The
IDR entity must review both offers and make a
determination based on certain factors as to which of the
submitted offers is the final payment amount.
The provider and the insurer have four business days
following the end of the open negotiation period to initiate
the IDR process by submitting a notice to the other party
and the federal government. In some instances, a provider
and insurer seeking resolution regarding multiple identical
(or similar) services can combine (or “batch”) the services
to be considered as part of a single IDR determination.
If initiated, the parties have three business days to jointly
select an IDR entity. If the parties do not make a selection
by the deadline, they must notify the Departments of the
Treasury, Labor, and Health and Human Services (triagencies) on the fourth business day and the tri-agencies
will randomly assign an IDR entity within six business days
of the IDR process initiation. Once selected, the IDR entity

must attest whether it satisfies conflict of interest
requirements within three business days. The IDR entity
also must determine whether the IDR process applies to the
situation and, if it is determined that the process does not
apply, the IDR entity must notify the tri-agencies and the
parties within three business days of the determination.

status, case mix, and scope of services of the facility that
furnished the service; and (5) demonstrations of good faith
efforts (or lack thereof) made by the provider or the insurer
to enter into network agreements and, if applicable,
contracted rates between the provider and the insurer during
the previous four plan years.

At the time the IDR entity is selected, both parties must pay
an administrative fee to the tri-agencies for participating in
the IDR process. This fee amount is set annually so that the
total amount of fees collected equals the total estimated cost
for the tri-agencies to carry out the IDR process. For 2022,
the administrative fee is $50. This fee is initially collected
by the IDR entity, which then remits the fee to the
government.

For air ambulance situations, the IDR entity is required to
consider the following (if submitted): (1) quality and
outcomes measurements of the provider that furnished the
service; (2) acuity of the individual receiving the service or
the complexity of furnishing the service to the individual;
(3) training, experience, and quality of the provider that
furnished the service; (4) ambulance vehicle type, including
the clinical capability level of the vehicle; (5) population
density of the pick-up location (e.g., urban, suburban, rural,
or frontier); and (6) demonstrations of good faith efforts (or
lack thereof) made by the provider or the insurer to enter
into network agreements and, if applicable, contracted rates
between the provider and the insurer during the previous
four plan years.

No later than 10 business days after the IDR entity has been
selected, the provider and the health insurer each must
submit to the IDR entity an offer for the payment amount;
any information requested by the IDR entity; and, if so
choosing, other information related to the offer. At this
time, both parties must pay a fee to the IDR entity for its
payment determination services. (This fee is in addition to
the administrative fee.) Each IDR entity can determine its
own fee amount, but generally these fees will fall in
between a range determined annually by the federal
government. For 2022, the fee range for a single
determination is $200-$500; for batched determinations, it
is $268-$670. IDR entity fees are held in a trust or escrow
account until a final determination is made.
After the IDR process is initiated but before there is a
determination, insurers and providers may continue to
negotiate a payment amount. If the parties reach an
agreement through negotiation during this period, the
agreed-upon rate is treated as the final payment rate. The
parties would split the IDR entity fee unless the parties
agree otherwise. The administrative fee is nonrefundable.
The IDR entity has 30 business days from the entity’s
selection to determine which of the submitted offers
represents the payment amount. To make this decision, the
IDR entity must consider the insurer’s 2019 median innetwork amount for the same or similar service provided by
a provider in the same or similar specialty in the same
geographic region (indexed for inflation), which is referred
to as the qualifying payment amount, or QPA. The IDR
entity also must consider a set of additional circumstances
if submitted by the parties (specified below), any
information requested by the IDR entity, and any other
information about the submitted offer supplied by the
provider or the insurer. To be considered, this information
must be credible and must not include information that the
IDR entity is prohibited from considering.
For all situations, excluding air ambulance, the IDR entity
is required to consider the following (if submitted): (1) the
level of training, experience, and quality and outcomes
measurements of the provider that furnished the service; (2)
the market share of the provider or insurer in the geographic
region where the service was provided; (3) the acuity of the
individual receiving the service or the complexity of
furnishing the service to the individual; (4) the teaching

In all situations, the IDR entity is prohibited from
considering usual and customary charges, the amount that
would have been billed by the provider for the service had
the surprise billing protections not applied, and the amounts
that public payors (including Medicare, Medicaid, the
Children’s Health Insurance Program [CHIP], or
TRICARE) would pay or reimburse the provider for the
service.
After considering the qualifying payment amount,
additional circumstances, and any additional information,
the IDR entity must select the offer that best represents the
value for the services under consideration. The IDR entity’s
decision is binding on both parties, unless there is fraud or
an intentional misrepresentation of facts. A binding
payment determination generally is not subject to judicial
review except in limited situations.
After the IDR entity makes a decision, if the payment
decision is more than the initial payment, the insurer must
pay the remaining balance to the provider within 30
calendar days of the decision. If the payment decision is
less than the initial payment, the provider must reimburse
the insurer within 30 calendar days of the decision. The
party whose offer is not chosen is responsible for paying the
IDR entity fee, and the IDR entity must refund the IDR
entity fee paid by the party with the chosen offer within 30
business days.
During the 90 calendar days after an IDR decision has been
made, the party that initiated the IDR process may not
subsequently attempt to initiate the IDR process to seek a
payment determination involving the same opposing party
and the same (or similar) services that were subject to the
initial determination. In instances where the same parties
are again in a surprise billing situation regarding the same
(or similar) service and the open negotiation period for such
services ends during this 90-day “cooling-off” period, either
party may initiate the IDR process within the 30 business
days following the cooling-off period.
