What is the Mental Health Parity and Addiction Equity Act (MHPAEA)?

Created by Kelly Knudsen, Modified on Fri, 19 Jan at 9:55 PM by Kelly Knudsen

The Mental Health Parity and Addiction Equity Act (MHPAEA) is a pivotal piece of U.S. legislation enacted in 2008 that addresses a critical issue in healthcare: the equitable treatment of mental health and substance use disorder (MH/SUD) services compared to medical and surgical care. Historically, insurance plans often provided limited coverage or imposed more restrictive requirements on MH/SUD treatments, leading to disparities in access and care. The MHPAEA was introduced to rectify this imbalance by mandating that insurance plans provide equal coverage for MH/SUD benefits, eliminating the stigma and barriers that individuals seeking mental health or addiction treatments often faced.


Under the MHPAEA, health insurance plans are prohibited from applying financial requirements or treatment limitations to MH/SUD benefits that are more restrictive than those applied to medical and surgical benefits. This encompasses various aspects, such as co-pays, deductibles, out-of-pocket maximums, visit limits, and other quantitative or non-quantitative treatment limitations. The law applies to both employer-sponsored group health plans and individual health insurance plans, ensuring that individuals seeking MH/SUD treatments are not subjected to discriminatory practices that hinder their access to necessary care.


The MHPAEA is a groundbreaking step toward achieving mental health and substance use disorder parity in the United States. By mandating equal coverage for mental health and addiction treatments, the law aims to improve the overall well-being of individuals by facilitating access to the care they need. Additionally, the MHPAEA promotes broader societal change by challenging the stigma surrounding mental health and encouraging a more inclusive and compassionate approach to healthcare coverage.
