OIG Finds Arizona Failed to Monitor MCO Mental Health Parity Compliance on Prior Authorization
The HHS Office of Inspector General found that Arizona did not ensure its selected Medicaid managed care organizations complied with federal mental health and substance use disorder parity requirements related to prior authorization processes. The review identified gaps in state oversight of whether MCOs applied comparable authorization standards for behavioral health and medical/surgical benefits, as required under the Mental Health Parity and Addiction Equity Act. The report recommends Arizona strengthen monitoring and enforcement mechanisms to verify MCO compliance with parity requirements. This review follows increased federal scrutiny of parity compliance across states and managed care plans.
Why it mattersState Medicaid agencies face heightened enforcement risk if they cannot demonstrate active oversight of MCO mental health parity compliance, particularly around utilization management practices like prior authorization that have been a focal point of recent federal enforcement.
