In New York, Aetna Is Denying Psychiatric Hospitalization Claims Even in Crisis Cases

Across New York City, Buffalo, Rochester, and surrounding counties, patients insured by Aetna are facing denials for inpatient mental health stays — including hospitalization after suicidal ideation, panic attacks, or manic episodes.

Common CPT/HCPCS codes involved:

  • H0018 – Residential/inpatient psychiatric treatment
  • 99223 – Initial hospital evaluation
  • 90791 – Psychiatric diagnostic evaluation

Frequent denial reason codes from Aetna:

  • CO-50: Not medically necessary
  • CO-151: Documentation insufficient for level of service
  • PR-96: Service not covered under policy
“We had a 16-year-old admitted after attempting suicide. Aetna approved the first 48 hours, then denied further stay mid-crisis. We used Counterforce Health’s appeal tool to fight back — and the rest of her treatment was approved.”
Dr. Rina Feldman, Child Psychiatrist, Queens

Why Aetna Denies Inpatient Mental Health, Even When It’s Clearly Urgent

Common reasons cited:

  • “Patient no longer meets inpatient criteria”
  • “Stabilization achieved — discharge appropriate”
  • “Care could be managed in a lower-acuity setting”

But these decisions often violate:

  • The Mental Health Parity and Addiction Equity Act (MHPAEA)
  • New York Mental Health and Substance Use Disorder Coverage Law (Timothy’s Law)
  • Medical judgment of the treating provider
“Aetna denied continuation after three days, but the patient was still hallucinating and required 24/7 monitoring. Counterforce’s tool cited both federal parity law and NY’s inpatient coverage mandates.”
