When Florida seniors compare Medicare Advantage and prescription drug plans for 2027, one number is easy to overlook:
The Medicare Star Rating.
Most people naturally focus first on premiums, copays, doctors, prescriptions, dental benefits, or an over-the-counter allowance. Those things absolutely matter. But Medicare also gives many Medicare Advantage and Part D plans a quality rating from 1 to 5 stars, and that rating can provide useful information about how a plan performs.
For Medicare beneficiaries in Tampa Bay, Apollo Beach, Riverview, Brandon, Bradenton, Sarasota, and throughout Florida’s Gulf Coast, understanding these ratings can add another useful layer to your 2027 Medicare comparison.
And for 2027, CMS is making changes to how those ratings are calculated.
What Is a Medicare Star Rating?
The Centers for Medicare & Medicaid Services evaluates Medicare Advantage and Part D plans using a five-star quality-rating system.
In general, more stars indicate stronger overall performance.
CMS says the Star Ratings system is designed to help Medicare beneficiaries compare the quality of health and prescription drug plans alongside other factors such as benefits and costs.
Depending on the type of plan, ratings can consider dozens of individual quality measures covering areas such as:
Health outcomes
Preventive care
Chronic-condition management
Member experience
Access to care
Customer service
Prescription drug safety and service
CMS currently evaluates Medicare Advantage plans that include prescription drug coverage using as many as 43 individual measures. Medicare Advantage-only plans and standalone Part D plans use smaller sets of measures.
What Do the Stars Mean?
The rating scale runs from one to five stars.
A higher rating generally reflects stronger performance across the measures Medicare uses to evaluate the plan.
But a five-star plan is not automatically the best plan for every beneficiary.
For example, a highly rated plan might still exclude your preferred physician, cover one of your medications differently, or have costs that do not fit your particular healthcare needs.
Think of Star Ratings as one tool in the decision—not the entire decision.
A good Medicare comparison should still include your doctors, prescriptions, expected medical services, premiums, copays, annual out-of-pocket limits, and other benefits.
CMS Is Changing the Star Ratings System
CMS finalized several changes that affect Medicare Advantage and Part D Star Ratings beginning with the 2027 ratings cycle.
One of the largest changes is an effort to make the ratings focus more heavily on measures that can meaningfully distinguish one plan from another.
CMS is removing 11 measures that primarily involved administrative processes or areas where most plans performed similarly and therefore provided relatively little useful differentiation for beneficiaries.
CMS says the goal is to focus the system more heavily on:
Clinical care
Health outcomes
Patient experience
Meaningful differences in plan performance
That can make Star Ratings more useful as a consumer comparison tool rather than simply rewarding plans for administrative measures where nearly everyone receives similar scores.
Behavioral Health Is Getting More Attention
CMS is also adding a new Medicare Advantage quality measure focused on depression screening and follow-up care.
The new measure begins with the 2027 measurement year and is scheduled to affect Star Ratings beginning with the 2029 ratings.
This reflects a broader move toward measuring outcomes that directly affect beneficiary health rather than focusing only on administrative performance.
CMS also chose to retain its diabetes eye-exam measure, recognizing the importance of preventive eye care for people with diabetes.
For beneficiaries, these types of measurements can provide insight into how seriously a plan approaches preventive care and chronic-condition management.
Why Star Ratings Matter When Comparing Florida Medicare Plans
Imagine you're comparing two Medicare Advantage plans available in Hillsborough County.
Both have similar premiums.
Both include your prescriptions.
Both include your primary care physician.
At that point, the Star Rating may provide another meaningful point of comparison.
One plan might have stronger ratings for customer service, preventive care, management of chronic conditions, or member experience.
That doesn't automatically make it the correct choice—but it gives you information beyond the benefits printed on the first page of a plan brochure.
This can be particularly valuable when several plans appear similar on paper.
Don't Confuse Star Ratings With Benefits
A Star Rating is a measurement of quality and performance.
It is not a measurement of how generous a plan's benefits are.
A four-star plan does not necessarily have better dental coverage than a three-and-a-half-star plan.
A five-star plan does not necessarily have lower hospital copays.
And a plan with a strong rating may not include your particular doctors.
This is why Medicare plans should be compared in multiple dimensions.
For most beneficiaries, the practical questions remain:
Are my doctors covered?
Are my prescriptions covered?
What could I pay when I use healthcare?
How high is my annual out-of-pocket exposure?
What benefits will I realistically use?
Then Star Ratings can help you compare quality between otherwise suitable choices.
There's Another Reason Five-Star Plans Matter
Five-star plans can also have special enrollment significance.
Medicare generally allows beneficiaries to switch into a five-star Medicare Advantage, Medicare Cost, or Part D plan using a Five-Star Special Enrollment Period, if an eligible five-star plan is available in their area and other Medicare requirements are satisfied.
That opportunity is generally available once between December 8 and November 30 of the following year.
However, switching plans can affect prescription coverage and other benefits, so beneficiaries should carefully review the new plan before making a change.
A five-star rating by itself should never be the only reason to switch.
Where Can You See a Plan’s Star Rating?
Star Ratings are displayed through Medicare's plan-comparison resources.
When reviewing Medicare Advantage or Part D plans, you can compare quality ratings alongside premiums, prescription coverage, and other plan information.
CMS publishes Medicare Advantage and Part D quality information each year and makes performance data available to beneficiaries and the public.
This makes Star Ratings one of the more transparent ways to compare overall plan performance.
What Florida Seniors Should Do for 2027
When Medicare Annual Enrollment begins on October 15, don't compare plans using only one number.
Look at the complete picture.
Start with the things most directly tied to your healthcare:
Your physicians and specialists
Your prescriptions
Your preferred hospitals
Medical copays
Prescription costs
Annual out-of-pocket limits
Then look at the plan's Star Rating and individual quality information.
If two plans both appear to meet your needs, quality ratings can help provide additional context.
Frequently Asked Questions
What is the highest Medicare Star Rating?
Five stars is the highest Medicare Advantage or Part D Star Rating.
Does a five-star plan mean it is automatically the best Medicare plan?
No. Star Ratings measure quality and performance, but they do not tell you whether the plan includes your doctors, covers your medications appropriately, or has costs and benefits that fit your individual needs.
Are Medicare Star Ratings changing for 2027?
Yes. CMS finalized changes that remove 11 measures from the Star Ratings system and place greater emphasis on meaningful clinical outcomes, patient experience, and quality differences between plans.
Do Star Ratings affect Medicare Advantage plans financially?
Yes. CMS uses Star Ratings in determining eligibility for Medicare Advantage quality bonus payments, which can affect plan payments and rebates.
Can I switch to a five-star Medicare plan outside Annual Enrollment?
In certain circumstances, Medicare provides a Five-Star Special Enrollment Period that may allow eligible beneficiaries to move to an available five-star plan. Beneficiaries should review the full coverage before switching.
Use Star Ratings as Part of the Bigger Picture
Medicare Star Ratings can be valuable—but they work best when used alongside the information that affects your everyday healthcare.
A plan's quality matters.
So do your doctors, medications, hospital costs, prescription coverage, and financial exposure.
