Medicare Advantage Prior Authorization: Challenges and Compliance Insights
Recent analyses by the Office of Inspector General (OIG) have brought attention to the prior authorization practices employed by Medicare Advantage insurers, identifying significant denial rates for post-acute care services. These reports emphasize potential compliance and operational challenges within the Medicare Advantage sector, crucial for health insurers to address.
OIG's findings reveal that Medicare Advantage plans are declining many prior authorization requests for costly post-acute care services. Denials were issued for 65% of long-term care hospital (LTCH) requests and 54% for inpatient rehabilitation facility (IRF) requests, whereas skilled nursing facility (SNF) requests faced a 12% denial rate. These figures greatly exceed the average denial rate of below 8% for all services previously determined by KFF.
The use of prior authorization aims to curb unnecessary utilization and manage healthcare expenses. Almost all Medicare Advantage enrollees are now subject to prior authorization for high-cost services, with projections indicating 95% of plans will require it for SNF stays by 2026. According to the Medicare Payment Advisory Commission, costs for these services in 2023 averaged $43,000 for LTCHs, $24,000 for IRFs, and $16,000 for SNFs.
The practical implications of these denials include delays in accessing needed care, averaging five to six days, and potentially increasing out-of-pocket expenses due to cost-sharing responsibilities during extended hospital stays. This raises concerns about the efficiency of current prior authorization processes.
Furthermore, the reports indicate that appeals frequently result in the approval of previously denied services, highlighting potential efficiency gaps in prior authorization decisions. Specifically, 36% of LTCH, 43% of IRF, and 95% of SNF denials were overturned upon appeal, prompting questions about the initial denial process and its appropriateness.
These findings align with previous analyses showing higher denial rates for post-acute care services by leading Medicare Advantage insurers from 2019 to 2022. Despite this, a gap remains in publicly available detailed data on prior authorization practices, potentially hindering efforts to evaluate and reform these processes effectively.
To address these challenges, the Centers for Medicare & Medicaid Services (CMS) have initiated a pilot to gather detailed data at the plan and service level, with a mandate for this information by 2027. This initiative aims to enhance transparency and accountability, providing insurers with improved insights into their prior authorization decisions' impact and efficiency. For insurers, aligning operational practices with regulatory expectations and preparing for future data reporting requirements is crucial.
