Questions people usually ask

What does a 5 star Medicare plan mean?
It means CMS rated the plan's quality, member satisfaction, and performance in the highest tier available — a strong signal, though not a guarantee that it's the right fit for your specific doctors or budget.

How do I compare Medicare Advantage star ratings?
Use the Medicare Plan Finder to search by ZIP code, then look at each plan's overall star rating side by side with your doctors, prescriptions, and total cost — not the rating in isolation.

Are Medicare Part D plans star-rated too?
Yes — Medicare Part D star ratings and Medicare prescription drug plan star ratings work on the same one-to-five scale, scored on different measures specific to drug coverage and pharmacy service.

What makes a Medicare Advantage plan 5 stars?
Consistently strong performance across CMS's quality categories — helping members stay healthy, manage chronic conditions, respond well to complaints, and deliver solid customer service — all rolled into one overall score.

Can I switch to a 5-star plan anytime, or only during Annual Enrollment?
If a 5-star plan is available in your area, the 5-star special enrollment period lets you switch into it once per calendar year, outside the standard Annual Enrollment window — in addition to your usual enrollment opportunities.

The bottom line

Star ratings are one of the most useful shortcuts Medicare offers for judging plan quality — but they're a shortcut, not the whole decision. Use them to narrow a long list down to the plans actually worth a closer look, then check the specifics that the stars alone can't tell you: your network, your formulary, and your real total cost.

Think of the star rating as the first filter, not the final answer. It tells you which plans are worth spending your limited comparison time on — the real decision still comes down to whether that quality lines up with the doctors you see and the medications you actually take.

If you'd rather have someone else run that comparison with you, a licensed agent can check which 5-star Medicare Advantage plans are actually available in your area, and how they stack up against your specific doctors and prescriptions — at no cost to you.
