The Mental Health Parity and Addiction Equity Act
Guidance for webpage that provides background on the Mental Health Parity and Addiction Equity Act of 2008 (MHPAEA).
Issued by: Centers for Medicare & Medicaid Services (CMS)
Issue Date: October 25, 2011
The Paul Wellstone and Pete Domenici Mental Health Parity and Addiction Equity Act of 2008 (MHPAEA) is a federal law that generally prevents group health plans and health insurance issuers that provide mental health or substance use disorder (MH/SUD) benefits from imposing less favorable benefit limitations on those benefits than on medical/surgical benefits.
MHPAEA originally applied to group health plans and group health insurance coverage and was amended by the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010 (collectively referred to as the “Affordable Care Act”) to also apply to individual health insurance coverage. HHS has jurisdiction over public sector group health plans (referred to as “non-Federal governmental plans”), while the Departments of Labor and the Treasury have jurisdiction over private group health plans.
Employment-related group health plans may be either “insured” (purchasing insurance from an issuer in the group market) or “self-funded.” The insurance that is purchased, whether by an insured group health plan or in the individual market, is regulated by the State’s insurance department. Group health plans that pay for coverage directly, without purchasing health insurance from an issuer, are called self-funded group health plans. Private employment-based group health plans are regulated by the Department of Labor. Non-Federal governmental plans are regulated by HHS. Contact your employer’s plan administrator to find out if your group coverage is insured or self-funded and to determine what entity or entities regulate your benefits.
MHPAEA does not apply directly to small group health plans, although its requirements are applied indirectly in connection with the Affordable Care Act’s essential health benefit (EHB) requirements as noted below. The Protecting Affordable Coverage for Employees Act amended the definition of small employer in section 1304(b) of the Affordable Care Act and section 2791(e) of the Public Health Service Act to mean generally an employer with 1-50 employees, with the option for states to expand the definition of small employer to 1-100 employees. The Employee Retirement and Income Security Act and the Internal Revenue Code also define a small employer as one that has 50 or fewer employees. (Some states may have mental health parity requirements that are stricter than federal requirements. To view State specific information visit www.ncsl.org, and on the right hand side of the page enter "mental health parity" then select "State Laws Mandating or Regulating Mental Health Benefits".)
The Mental Health Parity Act of 1996 (MHPA) provided that large group health plans cannot impose annual or lifetime dollar limits on mental health benefits that are less favorable than any such limits imposed on medical/surgical benefits.
MHPAEA preserves the MHPA protections and adds significant new protections, such as extending the parity requirements to substance use disorders. Although the law requires a general equivalence in the way MH/SUD and medical/surgical benefits are treated with respect to annual and lifetime dollar limits, financial requirements and treatment limitations, MHPAEA does NOT require large group health plans or health insurance issuers to cover MH/SUD benefits. The law's requirements apply only to large group health plans and health insurance issuers that choose to include MH/SUD benefits in their benefit packages. However, the Affordable Care Act builds on MHPAEA and requires coverage of mental health and substance use disorder services as one of ten EHB categories in non-grandfathered individual and small group plans.
Key changes made by MHPAEA, which is generally effective for plan years beginning after October 3, 2009, include the following:
There are certain exceptions to the MHPAEA requirements.
Except as noted below, MHPAEA requirements do not apply to:
Note, these exceptions do not apply to those non-grandfathered plans in the individual and small group markets that are required by Affordable Care Act regulations to provide EHB that comply with the requirements of the MHPAEA regulations.
A final regulation implementing MHPAEA was published in the Federal Register on November 13, 2013. The regulation is effective January 13, 2014 and generally applies to plan years (in the individual market, policy years) beginning on or after July 1, 2014. See http://www.gpo.gov/fdsys/pkg/FR-2013-11-13/pdf/2013-27086.pdf for the full text of the final regulation. This followed an interim final regulation, which was published in the Federal Register on February 2, 2010 and generally applies to plan years beginning on or after July 1, 2010. See http://edocket.access.gpo.gov/2010/pdf/2010-2167.pdf - Opens in a new window for the full text of the regulation.
The final regulation applies to non-Federal governmental plans with more than 50 employees, and to group health plans of private employers with more than 50 employees. It also applies to health insurance coverage in the individual health insurance market. It does not apply to group health plans of small employers (except as noted above in connection with the EHB requirements). Like the statute, it does not require group health plans to provide MH/SUD benefits. If they do, however, the financial requirements and treatment limitations that apply to MH/SUD benefits cannot be more restrictive than the predominant requirements and limitations that apply to substantially all of the medical/surgical benefits.
The provisions of the regulation include the following:
Medicare, Medicaid, and the Children's Health Insurance Program (CHIP) are not group health plans or issuers of health insurance. They are public health plans through which individuals obtain health coverage. However, provisions of the Social Security Act that govern CHIP plans, Medicaid benchmark benefit plans, and managed care plans that contract with State Medicaid programs to provide services require compliance with certain requirements of MHPAEA. See https://www.federalregister.gov/articles/2016/03/30/2016-06876/medicaid-and-childrens-health-insurance-programs-mental-health-parity-and-addiction-equity-act-of for the final rule regarding application of requirements of MHPAEA to Medicaid MCOs, CHIP, and Alternative Benefit (Benchmark) Plans.
