Mental health parity
A federal and state law requiring most insurance plans to cover mental health and substance use care at the same level as physical health care.
What mental health parity is
Mental health parity is the legal requirement that insurance plans cover mental health and substance use care at no worse a level than they cover medical or surgical care. The federal Mental Health Parity and Addiction Equity Act (MHPAEA) of 2008 sets the baseline; New Jersey adds stronger state-level rules on top.
What it looks like in practice
Parity affects what your plan can and can't do. Examples of what's covered:
- A plan can't charge a higher copay for therapy than for a regular doctor visit
- A plan can't apply a stricter visit limit on mental health than on physical health
- A plan can't impose more aggressive prior authorization on therapy than on comparable medical care
- A plan can't require longer waits for mental health benefits than for medical benefits
Parity applies to most employer-sponsored plans, Medicaid (NJ FamilyCare), and plans bought through the New Jersey marketplace. It does not apply to short-term plans, faith-based health-share arrangements, or grandfathered plans — but those are increasingly rare.
When this matters for you
If an insurance plan tells you mental health is “not covered” or imposes harsher rules than for medical care, that may violate parity. New Jersey’s Department of Banking and Insurance investigates parity complaints. We can help you understand whether the rules a plan is enforcing are legal — ask at intake.
