Medicare Advantage Star Ratings: What They Actually Mean

Every fall, Medicare assigns a star rating — from 1 to 5 — to each Medicare Advantage plan, based on how that plan performed over the previous year. The rating is a snapshot of past performance, not a promise about how the plan will treat you personally, and it's worth understanding what's actually being measured before you let a star count sway your decision.

The rating pulls from several broad categories: how well the plan helps members stay healthy (things like screening and vaccination rates), how effectively it manages chronic conditions such as diabetes or heart disease, how members rate their overall experience and ease of getting care, how many complaints were filed against the plan, and how responsive the plan's customer service is when you call with a question or problem.

Because the rating is calculated per plan, per county, two plans from the same insurance carrier can carry different star ratings depending on where you live. A plan that scores well in one part of Broward County isn't automatically the same plan, with the same performance, if it's offered a county over — so it's worth checking the rating for the specific plan available at your address, not just the carrier's reputation in general.

Star ratings are recalculated every year and published in the fall, ahead of the Annual Enrollment Period. A plan's rating can go up, stay the same, or go down from one year to the next, which means a plan you researched last year may carry a different rating today. Because this changes annually, it's worth confirming the current rating before making a decision rather than relying on what you remember from a prior year.

In some cases, a plan that consistently earns a high rating may open a Special Enrollment Period that lets members switch into it outside the usual enrollment windows, if such a plan is available where you live. Whether this applies to your situation depends on the specific plans available in your area and the current rules, so it's best to confirm directly rather than assume it applies.

What the star rating doesn't tell you is just as important as what it does. It doesn't say whether your specific doctors are in the plan's network, whether your prescriptions are covered on favorable terms, or what your out-of-pocket costs will look like for the care you actually use. A plan with a strong rating and a plan with a modest one can both work well or poorly for you personally, depending on those details.

A high star rating can be a useful general signal that a plan has historically run smoothly for its members, but it shouldn't be the only factor in your decision. Pairing the rating with a look at your own doctors, medications, and typical care needs gives a much fuller picture than the number alone.
