(2) Coverage under this section must include: (a) habilitative or rehabilitative care that is prescribed, provided, or ordered by a licensed physician, including but not limited to professional, counseling, and guidance services and treatment programs that are medically necessary to develop and restore, to the maximum extent practicable, the functioning of the covered child; and (b) medically necessary therapeutic care that is provided as follows: (i) up to 104 sessions per year with a speech-language pathologist licensed pursuant to Title 37; (ii) up to 52 sessions per year with a physical therapist licensed pursuant to Title 37; and (iii) up to 52 sessions per year with an occupational therapist licensed pursuant to Title 37. (3) Habilitative and rehabilitative care includes medically necessary interactive therapies derived from evidence-based research, including intensive intervention programs and early intensive behavioral intervention. (4) Benefits provided under this section may not be construed as limiting physical health benefits that are otherwise available to the covered child. (5) (a) Coverage under this section may be subject to deductibles, coinsurance, and copayment provisions. (b) Special deductible, coinsurance, copayment, or other limitations that are not generally applicable to other medical care covered under the plan may not be imposed on the coverage for Down syndrome therapies provided for under this section. (6) When treatment is expected to require continued services, the insurer may request that the treating physician provide a treatment plan consisting of diagnosis, proposed treatment by type and frequency, the anticipated duration of treatment, the anticipated outcomes stated as goals, and the reasons the treatment is medically necessary. The treatment plan must be based on evidence-based screening criteria. The insurer may ask that the treatment plan be updated every 6 months. (7) As used in this section, "medically necessary" means any care, treatment, intervention, service, or item that is prescribed, provided, or ordered by a physician licensed in this state and that will or is reasonably expected to: (a) reduce or improve the physical, mental, or developmental effects of Down syndrome; or (b) assist in achieving maximum functional capacity in performing daily activities, taking into account both the functional capacity of the recipient and the functional capacities that are appropriate for a child of the same age.
