What the Federal Law (MHPAEA) Already Required
The Paul Wellstone and Pete Domenici Mental Health Parity and Addiction Equity Act of 2008 (MHPAEA) required large group health plans to provide parity between behavioral health and medical/surgical benefits. The ACA expanded this to most plans and designated mental health and SUD treatment as essential health benefits. However, federal enforcement has been inconsistent, and many plans continued using non-quantitative treatment limitations (stricter preauthorization, shorter review cycles, lower reimbursement) to effectively under-cover behavioral health.
What NJ's A2031/S1339 Added
The NJ law strengthens enforcement. It requires individual and group health plans to conduct regular audits demonstrating that their management of behavioral health benefits is on par with medical benefits. Insurers must submit annual reports to state regulators, who report to the legislature. The law also empowers the Department of Banking and Insurance to investigate complaints. It took effect June 2019.
What This Means for Addiction Treatment Coverage
Your state-regulated plan (Horizon BCBSNJ, AmeriHealth NJ, Aetna, Cigna, UnitedHealthcare, Oscar — roughly) cannot: require stricter preauthorization for rehab than for a surgery; impose lower visit caps or day limits than for comparable medical conditions; charge higher copays or coinsurance; exclude medications (MAT) that it would cover for other chronic conditions; delay emergency care. If any of these happen, it may be a parity violation.
How to Appeal a Denial
Step 1: Request the denial in writing, including the clinical rationale. Step 2: Request the plan's medical necessity criteria (they must provide under ERISA and NJ law). Step 3: File an internal appeal through the plan. Step 4: If denied again, request external review through the NJ Department of Banking and Insurance. Step 5: Contact NJ CHAMP at 1-888-614-5400 — the state's dedicated parity appeal hotline. Our placement advisors can walk you through this.
Plans NOT Governed by NJ Law
Self-insured employer plans (ERISA) are regulated federally, not by NJ. They still must comply with MHPAEA but enforcement goes through the U.S. Department of Labor EBSA (1-866-444-3272). Federal plans (FEHB, TRICARE) have their own rules. NJ FamilyCare (the state's health coverage program) sits under separate rules administered by the NJ Department of Human Services — ReachNJ at 1-844-REACHNJ is the right first call for that coverage.
