New Jersey's Insurance Parity Laws for Addiction Treatment

The federal law: parity

The Mental Health Parity and Addiction Equity Act of 2008 requires that when a health plan covers mental health and substance use treatment, it cannot apply stricter limits to that care than it applies to comparable medical care. That means no lower visit caps, no higher copays, and, crucially, no tougher prior authorization or medical-necessity standards for addiction treatment than for, say, a cardiac admission. The Affordable Care Act extended this to individual and small-group plans by making substance use treatment an essential health benefit. Parity applies to nearly every plan, including self-funded employer plans. It does not set a specific number of covered days; it sets a comparison.

The New Jersey law: specific numbers

In February 2017 New Jersey enacted a substance use disorder treatment law, often referred to by its chapter number, P.L. 2017, c. 28, that goes further than parity by naming what state-regulated plans must do. As written, the law requires those plans to cover:

• Up to 180 days per plan year of inpatient and outpatient substance use disorder treatment when medically necessary, at in-network facilities
• The first 28 days of an inpatient stay without concurrent or retrospective medical-necessity review; prior authorization is barred for the full 180 days
• The first 28 days of intensive outpatient or partial hospitalization without retrospective medical-necessity review
• The 180 days are counted in inpatient days: partial hospitalization and intensive outpatient count as inpatient days, and each unused inpatient day can be exchanged for two outpatient visits, so it is one shared budget, not six months of residential care plus separate outpatient coverage
• Medications used to treat substance use disorder without prior authorization
• All of this subject only to the plan’s ordinary deductible, copay, and coinsurance, with no separate limits

The practical effect is that a New Jersey resident on a covered plan can be admitted to an in-network detox or residential program and stay four weeks before the insurer is allowed to start asking whether the care is necessary.

Which plans the New Jersey law covers, and which it does not

This is the part that matters most and is understood least. New Jersey can only regulate plans it has authority over: individual plans, small-group and large-group plans that an insurer fully insures, the State Health Benefits Program, and the School Employees’ Health Benefits Program. It cannot regulate self-funded employer plans, where the employer pays claims itself and hires an insurer only to administer them, because those are governed by federal law. Many large employers self-fund. The card looks identical.

Self-funded plans still owe you federal parity: they cannot review addiction treatment more strictly than medical care. They just do not owe you the 180 days.

Using the law on the phone

Facilities’ utilization staff know the law and handle most of this. Where it helps to know it yourself is when an admission is being delayed “pending authorization” at an in-network program on a state-regulated plan, or when a stay is cut short before day 28. In both cases, the sentence that moves things is: “This is a fully insured New Jersey plan and in-network treatment does not require prior authorization for the first 180 days under the 2017 law. Please note that on the file and give me a reference number.”

Appeals

Denials, including mid-stay denials of continued care, can be appealed. Every plan must offer an internal appeal, and for ongoing care you can request an expedited one, decided within days. If the internal appeal fails, state-regulated plans go to the Independent Health Care Appeals Program run by the New Jersey Department of Banking and Insurance, where an outside reviewer decides. Self-funded plans use a federal external review through an independent organization instead. Ask the facility to file, ask your clinician to write the medical-necessity letter, and cite parity: the plan must show that it applies the same standard to comparable medical care. You can also file a complaint with the Department of Banking and Insurance if you believe a state-regulated plan is breaking the 2017 law.

What the laws do not do

They do not make an out-of-network program in-network. They do not cover a facility outside New Jersey under the 28-day rule. They do not stop a plan from applying its deductible and coinsurance. And they do not help if a plan has no addiction benefit at all, which is rare but possible for some grandfathered and short-term plans.
