Do you trust that your insurance plan manages authorization approvals without delaying necessary medical care?

Medicare Advantage enrollees experience significantly longer acute care stays before being transferred to rehabilitation or long-term care facilities than those on traditional Medicare. The American Hospital Association attributes these delays to intensive prior authorization and utilization management practices.

Why it matters

Discharge delays create significant operational strain and capacity bottlenecks for hospitals, as administrative reviews frequently override clinical recommendations. These utilization management practices often steer patients to less intensive care settings, impacting both facility throughput and patient outcomes.

In 2023, Medicare Advantage enrollees faced median pre-transfer waits of nine days for rehabilitation and 21 days for long-term hospitals, compared to six and 13 days, respectively, for fee-for-service. CMS rules currently mandate that plan expedited requests be resolved within 72 hours.

The players

American Hospital Association

The national trade association representing nearly 5,000 hospitals, health systems, and other care providers.

Medicare Payment Advisory Commission

An independent congressional agency that provides the federal government with policy analysis on the Medicare program.

Centers for Medicare & Medicaid Services

The federal agency responsible for administering Medicare, Medicaid, and the Children's Health Insurance Program.

The details

Medicare Advantage plans frequently employ peer-to-peer reviews and prior authorization mandates that slow the transition from acute to post-acute care. When hospitals seek to transfer patients to inpatient rehabilitation facilities, these managed care requirements often stall the process or divert patients to skilled nursing facilities instead. This administrative friction forces hospitals to maintain beds for patients ready for discharge while awaiting payer decisions.

2023 was the period of collection for the utilization data reported by MedPAC.
2024 was the year CMS finalized its prior authorization rule for Medicare Advantage plans.
2025 marked the period where post-acute discharge delays were identified as a top challenge.
October 2, 2026, was the date the AHA issued its response to the MedPAC findings.

Market Landscape

These findings highlight a deepening conflict between managed care utilization strategies and hospital throughput goals. This tension persists even after the implementation of the 2024 CMS prior authorization rule, which sought to standardize administrative response times.

Hospital operators should track the average duration of stay for Medicare Advantage patients versus fee-for-service to identify specific payer-related bottlenecks. Monitoring the administrative time cost of these prior authorization requirements is essential for accurate resource allocation and capacity planning.

The takeaway

The administrative hurdles in Medicare Advantage significantly extend patient stays, complicating throughput and care continuity. Leadership should audit internal utilization management workflows to ensure staff are maximizing the 72-hour CMS window for expedited request resolutions.
