Milliman Parity Compliance Guide

This Guide may be used by appropriate state agencies, such as Departments of Insurance or State Attorneys General, for their reviews of MHPAEA compliance with health plans or by any other entity that is charged with assuring compliance with aspects of the law (e.g., external review entities).

This document strives to provide an understandable and comprehensive guide to compliance with MHPAEA. As the IFR finalized and subregulatory guidance is issued and we obtain additional information we deem helpful in compliance efforts, we will periodically update this Guide. We welcome questions and/or suggestions regarding the content of this document. Inquiries should be directed to Steve Melek at, Clare Miller at, or Sam Muszynski at
