OIG: Medicare Advantage plans inappropriately deny rehab, nursing home care at high rates
The HHS Office of Inspector General reported a pattern of inappropriate prior authorization denials for long-term and rehab care in Medicare Advantage. The report, which analyzed 2024 data, found plans frequently denied stays at long-term acute care hospitals and inpatient rehabilitation facilities, often reversing those denials on appeal. This signals increased payer scrutiny on post-acute care authorizations. Watch for increased denial rates on claims for CPT codes 99304-99310 and 99315-99316, and corresponding DRGs. Prepare to appeal with detailed clinical documentation for any MA patient needing skilled nursing or rehab placement. The OIG has urged CMS to increase oversight of MA denials for these services.
