The Mental Health Parity and Addiction Equity Act (MHPAEA) is a federal law that was passed in 2008 to promote health insurance coverage for mental health and substance abuse treatment. 

The right mental health parity and addiction act requires health insurance plans to cover mental health and substance abuse treatment in the same way they cover medical and surgical services.

The purpose of the MHPAEA is to ensure that health insurance plans provide benefits for mental health and substance use disorders that are equal to the benefits provided for medical and surgical services. 

The law also prohibits insurance plans from placing more restrictive limits on mental health and substance abuse benefits than on medical and surgical benefits.

The MHPAEA has been beneficial for people with mental health and substance use disorders by providing them with access to the same level of health coverage as those with medical and surgical conditions. 

This has made it easier for people to access the care they need and has helped to reduce healthcare costs by ensuring that people are able to receive effective treatment for their conditions.
