Guide to help employers comply with parity law: The Mental Health Parity and Addiction Equity Act of 2008 (MHPAEA) requires group health plans that cover more than 50 employees and that offer coverage for mental or substance use disorders to provide such coverage at parity with medical-surgical benefits with respect to financial requirements and treatment limitations. The law, which is estimated to affect 113 million people, including 82 million enrolled in self-insured plans, and the detailed regulations for implementing it can be confusing and can make compliance a difficult and time-consuming task. At the request of the Partnership for Workplace Mental Health, a subsidiary of the American Psychiatric Association, Milliman, Inc., has prepared a reference document designed to help employers understand MHPAEA requirements and how to assess compliance with the parity tests and standards embedded in the law and regulations. The 30-page guide, Employer Guide for Compliance With the Mental Health Parity and Addiction Equity Act, provides a series of questions that the employer’s health plan can use to conduct a thorough assessment of the plan’s compliance with MHPAEA. The guide is available at www.workplacementalhealth.org/erguide.
