Understanding Insurance Coverage for ABA Therapy in Princeton

New Jersey's autism coverage law, P.L. 2009, c. 115, is codified in several places, including N.J.S.A. 17B:27-46.1ii for group policies, 17B:27A-7.16 for individual plans, 17B:27A-19.20 for small employer plans, and 26:2J-4.34 for HMOs. Covered plans must pay for screening and diagnosis of autism and other developmental disabilities, and for medically necessary occupational, physical, and speech therapy, which cannot be denied because the treatment is not restorative. For members under 21 whose primary diagnosis is autism, plans must cover medically necessary behavioral interventions based on applied behavior analysis under a treatment plan, to the same extent as other medical conditions and with no limit on the number of visits. Insurers may request an updated treatment plan only once every six months unless the insurer and treating physician agree to more frequent review. The statute still includes an inflation-adjusted annual dollar maximum for ABA, but the Department of Banking and Insurance advised in Bulletin 10-02 that federal mental health parity law keeps many group health plans from applying it. Self-funded employer plans follow federal ERISA rules instead. NJ FamilyCare covers ABA for members under 21 with an autism diagnosis from a qualified health care professional, such as a physician or psychologist. Members receive these services through their managed care organization, which requires prior authorization, and the provider and plan handle that request together.
