Medicare Advantage Star Ratings: Why 4+ Matters (2026)
- Medicare rates every Advantage plan 1 to 5 stars on quality, service, and member outcomes.
- A star rating is really thousands of current members telling you how much friction they face.
- We focus on 4+ star plans, and generally avoid under-4 when a better option exists.
- There's a little-known 5-star Special Enrollment Period, you can switch to a 5-star plan once a year, almost anytime.
- A great premium or benefit means little if the plan scores poorly on actually delivering care.
The star rating might be the most underrated number in Medicare Advantage. People obsess over the premium and the benefits, then ignore the one figure that tells them what it's actually like to be a member of that plan. Let's fix that, because stars are your early-warning system.
What Do Star Ratings Measure?
Medicare scores every Advantage plan on a 1-to-5 star scale, updated yearly, based on dozens of measures across categories like:
Care quality
How well the plan keeps members healthy, screenings, managing chronic conditions, outcomes.
Customer service
How well the plan handles calls, appeals, and problems, the everyday experience.
Member satisfaction
What current members report about their experience with the plan.
Access & accuracy
How smoothly members get care, approvals, and accurate information.
What the star rating really tells you
Here's the key insight: a star rating is thousands of current members reporting how much friction they face. Denied claims, slow prior authorizations, poor customer service, access problems, the exact frustrations that make Medicare Advantage miserable when they happen, are what drag a plan's stars down. So a low rating isn't abstract. It's a warning that real people are having real trouble using that plan.
That's why we treat 4+ stars as a strong preference and generally steer away from under-4 plans when a better-rated option is available. Why sign up for known friction when you don't have to?

The 5-Star Secret: A Special Enrollment Period
You can switch to a 5-star plan almost anytime
Here's something most people don't know. Normally you can only change Advantage plans during specific windows. But there's a special rule: if a 5-star plan is available in your area, you can switch to it once per year, outside the normal enrollment periods (through a "5-star Special Enrollment Period," available most of the year).
What this means for you: if you're stuck in a mediocre plan and a 5-star plan is available near you, you're not trapped until fall. You have an escape hatch. It's one of the most useful and least-known rules in Medicare Advantage, and exactly the kind of thing we watch for our clients. Not every area has a 5-star plan, but where one exists, it's a powerful option.
Stars Aren't Everything, But They're the Foundation
A high star rating doesn't automatically make a plan right for you, it still has to cover your doctors, your drugs, and fit your budget (that's why we use a full 5-point evaluation). But a low rating is a strong reason to look elsewhere. Think of 4+ stars as the entry ticket: a plan should clear that bar before it's even worth considering the rest.
