Medicare Advantage Insurers Made Nearly 53 Million Prior Authorization Determinations in 2024

Medicare Advantage insurers made nearly 53 million prior authorization determinations in 2024, up from 49.8 million in 2023. They fully or partially denied 4.1 million, or 7.7%, of the prior authorization requests they received. Just 11.5% of all denials were appealed, but in the vast majority of those cases (80.7%) the initial denial was overturned.

Prior authorization determinations represent requests for approval that providers must submit before providing a service. Lawmakers of both major political parties have pressed insurers on their prior authorization practices, which consumers say unfairly erect barriers to needed care.

Premiums Are Decreasing for Many Stand-Alone Part D Drug Plans in a Number of States in 2026

This analysis finds that monthly premiums for many Part D stand-alone prescription drug plans (PDPs) in a number of states will be lower in 2026 than they were this year. At the same time, the total number of PDPs, which provide prescription drug coverage to people in traditional Medicare, will fall for the third year in a row, as insurers continue to scale back their offerings and adjust to higher costs under the redesigned Part D benefit, reflecting changes in the Inflation Reduction Act.
