Medicare Advantage 2025: A Comprehensive Guide

medicare Advantage Mandates: Prior Authorization Becomes the Norm for Costly Services

Washington D.C. – A meaningful majority of individuals enrolled in Medicare Advantage plans are now subject to prior authorization requirements for numerous higher-cost healthcare services. Data indicates that a staggering 99% of Medicare Advantage enrollees are in plans that necessitate this pre-approval process for at least some services in 2025.Prior authorization has become a common hurdle for beneficiaries seeking services such as skilled nursing facility stays (99% of enrollees), Part B drugs (98%), and inpatient hospital stays, both acute (96%) and psychiatric (93%). Outpatient psychiatric services also frequently require this step, affecting 80% of enrollees.Conversely, preventive services are rarely subject to prior authorization, with only 7% of enrollees facing this requirement.

Furthermore, the prior authorization mandate extends to some additional benefits offered by Medicare Advantage plans, including extensive dental services and hearing and eye exams for a majority of enrollees enrolled in plans that offer these benefits. The overall number of Medicare Advantage enrollees subject to prior authorization for one or more services has remained relatively consistent between 2024 and 2025.This contrasts sharply with traditional Medicare,which generally does not impose prior authorization requirements and does not mandate step therapy for Part B drugs.

While Medicare Advantage insurers are now obligated to disclose some data regarding the timeliness and utilization of prior authorization, comprehensive information on how these requests, denials, and appeals vary by service type, plan, or enrollee characteristics is not yet available. This is due to a lack of data collection and reporting by the Centers for Medicare & Medicaid Services (CMS).

The analysis is based on data from the Centers for Medicare & Medicaid Services (CMS) Medicare Advantage Enrollment, Benefit and Landscape files for the respective years. It’s critically important to note that KFF’s analysis, as 2022, excludes cost plans, PACE plans, hcpps, and MMPs to focus specifically on Medicare Advantage plans, as these other plan types may have different enrollment criteria and payment structures.

Deductibles: You may have a deductible to meet before your plan starts paying.

Copays & Coinsurance: These are the costs you share with the plan for covered services.

Out-of-Pocket Maximum: A crucial feature – this limits how much you’ll pay for covered services in a year. Once you reach this limit, the plan pays 100% of covered costs.

Provider Networks: Most MA plans use a network of doctors and hospitals. You’ll generally need to use in-network providers to get the highest level of coverage. HMO plans and PPO plans are common network types.
