Medicare advantage prior authorization data now public, but challenges remain

For many individuals enrolled in Medicare Advantage (MA) plans, the process of prior authorization can be a significant hurdle when seeking medical care [Medicare Rights Center]. This requirement means that beneficiaries need approval from their insurance plan before receiving certain services or medications, and denials can lead to delays or disruptions in treatment [Medicare Rights Center]. The Centers for Medicare & Medicaid Services (CMS) has been working to bring more transparency to this system, requiring MA organizations to publicly report data related to prior authorizations [Medicare Rights Center].

Reporting Requirements and Initial Challenges

As of April 1, 2026, a new regulation from CMS came into effect, mandating MA and other private health plans to publicly share specific data about their prior authorization practices [Medicare Rights Center]. This includes details on how often prior authorization is used, how many requests are denied, how many denials are overturned upon appeal, and the timeframes for processing these requests [Medicare Rights Center]. This reporting covers both standard and expedited requests, the latter being for urgent medical situations [Medicare Rights Center].

However, the initial implementation of this mandate has presented challenges for consumers. The data is reported at a contract level, meaning it often aggregates information from several plans, making it difficult for an individual to discern the specific metrics for their particular plan [Medicare Rights Center]. Furthermore, locating this information can be cumbersome, as some organizations have placed it in less obvious sections of their websites or even behind password protection [Medicare Rights Center]. This lack of clarity can undermine the utility of the data for beneficiaries attempting to make informed decisions about their healthcare coverage [Medicare Rights Center].

New Guidance for Improved Transparency

In response to these issues, CMS recently released updated guidance designed to improve how and where MA organizations report prior authorization data [Medicare Rights Center]. This new guidance aims to make the information more accessible and meaningful for people with Medicare, as well as for researchers and advocates [Medicare Rights Center]. The goal is to provide greater clarity on these practices, which KFF polling indicates are a source of ongoing struggle for many consumers [Medicare Rights Center].

Why Prior Authorization Matters to You

Prior authorization exists to help control healthcare costs and ensure that services are medically necessary. However, when the process is overly burdensome, it can create significant stress and potentially delay necessary care [KFF Medicare]. Reports indicate that insurers deny a substantial portion of standard prior authorization requests, with at least one in eight being denied across various markets in 2025 [KFF Medicare]. While plans do offer an appeals process, navigating these systems can be complex for patients, especially when they are already managing health concerns.

While this increased transparency from CMS is a welcome development, the effectiveness of these reporting requirements ultimately depends on how easily beneficiaries can access and understand the information. As The Health Almanac continues to monitor these developments, we encourage readers to familiarize themselves with their plan's specific requirements and to advocate for their care needs when encountering prior authorization hurdles.
