Mental Health Parity and Addiction Equity Act (MHPAEA)

The Centers for Medicare & Medicaid Services (CMS) issued a final rule that applies the requirements of the Mental Health Parity and Addiction Equity Act (MHPAEA) to Medicaid managed care organizations (MCOs), the Children's Health Insurance Program (CHIP), and Medicaid alternative benefit plans (ABPs). The rule requires Delaware and its contracted Medicaid/CHIP MCOs to be in compliance with the final parity rule by October 2, 2017. This includes providing documentation of parity compliance to the general public and posting this information to the State's Medicaid website by October 2, 2017.

The purpose of this posting is to provide public notice and receive public input for consideration regarding Delaware's draft report of compliance with the final rule.
