Mental Health Parity and Addiction Equity Act

All fully insured health plans sold to individuals, small employer groups, and large employer groups must include benefits for mental health and substance use disorder (MH/SUD) services. These benefits must be provided at the same level as benefits provided for physical illness, also known as “parity.” Self-funded health plans (commonly provided by large employers) aren’t required to cover MH/SUD services. If they do include this coverage, it must be provided in parity with benefits for physical illness.

Compliance Tools

The Parity Act is a federal law that requires health insurance companies to cover mental health and substance use disorder (MH/SUD) services in parity with medical and surgical (M/S) services. This includes a requirement that any treatment limitations in a benefit plan can be no more restrictive for MH/SUD services than they are for M/S services.
