Use of Prior Authorization in Medicare Advantage Exceeded 46 Million Requests in 2022

GAINING CLARITI: This analysis from KFF highlights the substantial increase in prior authorization requests for Medicare Advantage beneficiaries, exceeding 46 million in 2022. ▼

This trend affects skilled nursing facilities as they rely heavily on Medicare Advantage for reimbursement. The increasing use of prior authorization can lead to delays in care, increased administrative burden, and potential denials of necessary services for residents, impacting both the quality of care provided and the financial stability of the facility.


Virtually all enrollees in Medicare Advantage (99%) are required to obtain prior authorization for some services – most commonly, higher cost services, such as inpatient hospital stays, skilled nursing facility stays, and chemotherapy. This contrasts with traditional Medicare, where only a limited set of services require prior authorization. Prior authorization requirements are intended to ensure that health care services are medically necessary by requiring approval before a service or other benefit will be covered. Medicare Advantage insurers typically use prior authorization, along with other tools, such as provider networks, to manage utilization and lower costs. This may contribute to their ability to offer extra benefits and reduced cost sharing, typically for no additional premium, while maintaining strong financial performance.

Key Takeaways:

  • More than 46 million prior authorization requests were submitted to Medicare Advantage insurers on behalf of Medicare Advantage enrollees in 2022, up from 37 million in 2019.
  • In 2022, there were 1.7 prior authorization requests per Medicare Advantage enrollee, similar to the amount in 2019.
  • In 2022, insurers fully or partially denied 3.4 million (7.4%) prior authorization requests.
  • Just one in ten (9.9%) prior authorization requests that were denied were appealed in 2022.
  • The vast majority of appeals (83.2%) resulted in overturning the initial prior authorization denial.
  • Medicare Advantage insurers vary in their use of prior authorization.
