New York failed to ensure Medicaid insurers followed mental health parity rules: OIG
Impact on your practice
This audit provides concrete evidence of parity violations in a major state Medicaid program and creates enforcement leverage for therapists and advocates. Expect increased scrutiny of prior authorization practices nationally and potential regulatory action requiring MCOs to align mental health and medical denial rates.
Key facts
HHS OIG audit found New York Medicaid insurers denying mental health prior auth requests at rates far exceeding medical denials (70% vs. 25-30% for medical)
Audit examined 2023 data for 3 of 14 MCOs covering ~42% of NY Medicaid enrollees
One insurer showed 42% denial rate for community psychiatric support services; another 37% for partial hospitalization
OIG found state failed to ensure MCO compliance with federal parity requirements, creating access barriers for MH/SUD services

Policy changes drive denial patterns

[NY] A04566: Adopts the psychology interjurisdictional compact (Part A); adopts the recognition of emergency medical services personnel licensure interstate compact (Part B); adopts the interstate counseling compact (Part C).
If passed, A04566 would be transformative for New York mental health providers. Both psychologists and counselors would gain interstate licensure portability, dramatically expanding practice opportunities and reducing licensing friction. This is particularly significant given New York's large provider population.
[WA] HB1432: Improving access to appropriate mental health and substance use disorder services.
WA's HB1432 is now law and will take effect mid-2025. Therapists should review the full text to understand new access requirements, which may affect prior authorization processes, network participation, or documentation standards.
[OK] HB2049: Medicaid parity; coverage; mental health and substance use disorders; contract compliance; noncompliance reviews; Oklahoma Health Care Authority; complaints; publication of reports; effective date.
Oklahoma therapists treating Medicaid patients now have explicit parity enforcement mechanisms and public accountability for MCO compliance. This should reduce discriminatory prior authorization practices and coverage denials for behavioral health in Medicaid.
[MD] HB280: Health Insurance - Mental Health and Substance Use Disorders - Codification of Federal Requirements
Maryland therapists gain stronger state-level parity protections by embedding federal requirements into state insurance code. This creates dual enforcement pathways (state and federal) and may improve prior authorization consistency and coverage denials for mental health services.
