Medicare Advantage Star Ratings — How to Use Them
What CMS stars measure and what they do not replace.
Updated Jan 15, 20261 min read3 sources
Stars are a quality signal
CMS publishes star ratings for Advantage and Part D plans based on clinical and customer-experience measures. Higher stars can indicate better measured quality.
Stars do not guarantee your doctors are in-network or your drugs are cheap — still verify both.
Use stars as one input
Combine stars with total cost estimates, network checks, and drug reviews on Medicare.gov.
Ratings can change yearly; do not rely on last year's marketing alone.
