Imagine you’re comparing two Medicare Advantage plans for 2027.

Plan A: ⭐⭐⭐⭐⭐

5 Stars

Plan B: ⭐⭐⭐⭐

4 Stars

Which one should you choose?

At first glance, the answer seems obvious:

“The 5-Star plan. It has the better rating.”

But now imagine:

Plan A doesn’t include your cardiologist.

Plan B does.

Or:

Plan A doesn’t work as well with one of your important prescriptions.

Or:

Plan A has substantially higher cost-sharing for services you regularly use.

Now which one is better?

That’s why Medicare Star Ratings are useful—but shouldn’t make the entire decision for you.

A Star Rating measures plan quality. It does not measure how well a plan personally fits you.

Understanding that distinction can make you a much smarter Medicare shopper.

---

What Are Medicare Star Ratings?

The Centers for Medicare & Medicaid Services—CMS—uses a Star Ratings system to help Medicare beneficiaries compare the quality and performance of Medicare Advantage and Part D plans.

The scale runs from:

⭐ to ⭐⭐⭐⭐⭐

with 5 stars representing the highest overall quality rating.

CMS publishes Star Ratings annually, and the ratings appear through Medicare’s plan-comparison resources.

You can review Medicare plans through the official:

Medicare Plan Finder

CMS says the Star Ratings system is intended to help Medicare beneficiaries compare the quality of health and drug plans.

But quality isn’t the same thing as personal suitability.

---

Medicare Star Ratings at a Glance

Here’s a simple way to understand the scale.

Rating	General Meaning	How to Use It
⭐⭐⭐⭐⭐	Excellent	Strong quality signal
⭐⭐⭐⭐	Above average	Positive quality signal
⭐⭐⭐	Average	Look deeper
⭐⭐	Below average	Investigate carefully
⭐	Poor	Significant quality concern

Important: The right-hand column is our practical interpretation for comparison purposes—not an official CMS recommendation about whether you should enroll.

The rating should make you ask questions.

It shouldn’t make the decision for you.

---

What Do Medicare Star Ratings Actually Measure?

Star Ratings aren’t based on one survey question.

CMS evaluates multiple quality and performance measures.

For the current Star Ratings framework, CMS describes measures across five broad categories:

1. Outcomes
2. Intermediate outcomes
3. Process
4. Patient experience
5. Access

For the 2027 ratings, CMS says MA-PD contracts can currently be rated on up to 43 measures, MA-only contracts on up to 33 measures, and Part D plans on up to 12 measures.

The exact measures depend on the type of contract being rated.

---

What Does That Mean in Real Life?

Star Ratings can incorporate information related to areas such as:

Member experience

How beneficiaries experience the plan.

Complaints

Information involving member complaints and plan performance.

Access

Whether members can obtain needed care or medications.

Health outcomes

Measures related to health and clinical performance.

Medication performance

For Part D, measures include areas such as medication adherence and getting needed prescription drugs.

Quality improvement

CMS also evaluates aspects of whether plan quality is improving.

So:

Stars contain meaningful information.

The mistake is assuming they contain all the information you need.

---

The Medicare Plan Decision Pyramid

Here’s how I would place Star Ratings inside an actual Medicare comparison.

Priority	Question
1 — Critical	Are my doctors and specialists accessible?
2 — Critical	Are my preferred hospitals/facilities accessible?
3 — Critical	Are my prescriptions covered appropriately?
4 — Critical	What could I actually pay for healthcare?
5 — Important	Does the plan type/network fit how I receive care?
6 — Important	What rules could affect access to services?
7 — Helpful	What is the plan’s Star Rating?
8 — Helpful	Which supplemental benefits will I actually use?

That’s a very different comparison from:

“Sort by stars. Pick the first one.”

---

A 5-Star Plan Can Be Excellent—and Still Not Be Your Best Fit

This is the central concept.

Suppose you’re comparing two hypothetical Medicare Advantage plans.

Factor	Plan A	Plan B
Star Rating	⭐⭐⭐⭐⭐	⭐⭐⭐⭐
PCP	In network	In network
Cardiologist	❌ Not in network	✅ In network
Preferred hospital	✅	✅
Important prescriptions	Covered	Covered
Specialist copay	$50	$35
MOOP	$7,500	$5,500
Dental	Higher	Lower
Overall personal fit	Mixed	Strong

Which plan wins?

You can’t answer from the Star Rating alone.

Plan A may perform extremely well across CMS quality measures.

But Plan B might better fit this particular beneficiary’s healthcare.

Both statements can be true simultaneously.

---

Think of Star Ratings Like Hotel Ratings—but Not Exactly

A simple analogy helps.

Suppose you’re booking a hotel.

One property has outstanding reviews.

But it’s:

45 minutes from where you need to be.

Another hotel has slightly lower reviews but is:

across the street from your destination.

Which is better?

It depends on what you need.

Medicare works similarly, although healthcare is obviously much more consequential than booking a hotel.

A rating gives you information about quality.

It doesn’t know:

• Who your cardiologist is
• Which prescriptions you take
• Which hospital you prefer
• How often you travel
• What you can afford
• Whether you prefer an HMO or PPO
• Which supplemental benefits matter to you

That’s why:

Star Ratings are quality scores—not personal-fit scores.

---

Factor #1: Your Doctors

Before allowing a 5-Star rating to drive your decision, check your doctors.

That includes:

• Primary care physician
• Cardiologist
• Oncologist
• Endocrinologist
• Neurologist
• Orthopedist
• Other specialists

A high-quality Medicare Advantage plan that doesn’t fit your provider needs may not be your preferred choice.

---

Factor #2: Your Hospitals

Don’t stop with doctors.

Check:

Preferred hospital

Health system

Outpatient facilities

Specialty facilities you regularly use

A plan comparison should evaluate the healthcare ecosystem around you.

---

Factor #3: Your Prescriptions

Your prescriptions can completely change the comparison.

Before Open Enrollment, build an accurate medication list containing:

• Exact drug
• Dosage
• Quantity
• Frequency
• Brand/generic preference
• Pharmacy
• Mail-order preference

Our Medicare prescription-list guide explains how to build one specifically for plan comparisons.

Then check your medications against the plans you’re considering.

---

A 5-Star Plan Doesn’t Mean Every Drug Is Best for You Under That Plan

This distinction is important.

Part D quality measures can include prescription-related performance.

For example, CMS’s published 2027 measures include medication-adherence measures involving diabetes medications, hypertension medications and statins, along with measures related to member experience and getting needed prescription drugs.

That’s useful information about plan quality.

But it doesn’t answer:

“What will happen with MY exact medication?”

You still need to check:

Formulary

Tier

Pharmacy

Cost-sharing

Prior authorization

Step therapy

Quantity limits

That’s why your personal prescription comparison remains essential.

---

Factor #4: Your Actual Healthcare Costs

A high Star Rating doesn’t eliminate:

• Copays
• Coinsurance
• Deductibles
• Hospital cost-sharing
• Specialist costs
• Outpatient costs
• Prescription costs

And with Medicare Advantage, you should also review the plan’s:

Maximum out-of-pocket limit (MOOP).

Our guide to $0 Premium Medicare Advantage Plans explains why looking only at a monthly premium can hide significant differences in potential healthcare spending.

The same principle applies to stars.

Don’t look only at:

⭐⭐⭐⭐⭐

Look at the numbers underneath the rating.

---

Factor #5: HMO vs. PPO

Plan structure can have a major impact on how you receive healthcare.

An HMO may emphasize in-network care and operate differently from a PPO when it comes to out-of-network access and plan rules.

A PPO may provide additional flexibility but can have different costs and network considerations.

Neither is automatically better.

Our HMO vs. PPO Medicare Advantage comparison walks through the differences.

So if you’re comparing:

5-Star HMO

versus:

4-Star PPO

the question isn’t simply:

“Which has more stars?”

It may be:

“Which structure fits how I actually receive care?”

---

Factor #6: Supplemental Benefits

Once the core coverage fits, look at extras.

These can include:

• Dental
• Vision
• Hearing
• OTC
• Transportation
• Fitness
• Certain grocery or condition-specific benefits

Our 2027 Medicare Advantage extra-benefits guide explains why these should generally be evaluated after doctors, hospitals, prescriptions, costs and plan rules.

The same logic applies here.

Don’t choose:

5 stars + biggest dental

without examining the healthcare underneath.

---

So How Much Weight Should You Give Star Ratings?

Here’s a useful framework.

Green Light 🟢

5-Star plan + excellent personal fit

Doctors work.

Prescriptions work.

Costs fit.

Hospital works.

Plan structure fits.

Benefits are useful.

Excellent.

The rating reinforces an already strong fit.

---

Yellow Light 🟡

5-Star plan + questionable personal fit

Maybe:

• Specialist missing
• Prescription issue
• Higher MOOP
• Network concern

Don’t allow the stars to override those issues.

Investigate.

---

Blue Light 🔵

4-Star plan + excellent personal fit

Don’t automatically dismiss it because another plan has five stars.

Compare the whole package.

---

Red Light 🔴

Low-rated plan + questionable personal fit

Now you have concerns on both sides:

Quality concerns

and:

Personal-fit concerns.

That’s when deeper scrutiny becomes particularly important.

---

The Medicare Star Rating Scorecard

Here’s another tool readers can actually use.

Score each plan from:

0 = Poor

1 = Acceptable

2 = Strong

Category	Score
Doctors	/2
Specialists	/2
Hospitals	/2
Prescriptions	/2
Pharmacy	/2
Premium	/2
Medical costs	/2
MOOP	/2
Network structure	/2
Plan rules	/2
Supplemental benefits	/2
Star Rating	/2
TOTAL	/24

The exact scoring isn’t an official Medicare methodology.

It’s simply a consumer decision tool.

The important idea is that:

Star Rating gets a row—not the entire spreadsheet.

---

What Is Special About a 5-Star Medicare Plan?

There actually is something unique about 5-Star plans beyond the quality signal.

Medicare provides a:

5-Star Special Enrollment Period

If a Medicare Advantage Plan, Medicare drug plan or Medicare Cost Plan with a 5-Star overall rating is available in your area, Medicare says you may have an opportunity to switch to a 5-Star plan.

The 5-Star Special Enrollment Period can generally be used once between December 8 and November 30 of the following year.

That’s important.

But there’s another important part.

---

Don’t Use the 5-Star Special Enrollment Period Without Checking the Consequences

Medicare specifically warns that the type of 5-Star plan you switch into matters.

For example, moving between plans can affect prescription coverage depending on whether the new plan includes drug coverage.

Medicare warns that moving from a Medicare Advantage plan with drug coverage to a 5-Star Medicare Advantage plan without drug coverage could leave you without prescription drug coverage until another enrollment opportunity and could potentially expose you to a Part D late-enrollment penalty.

So:

5-Star SEP ≠ automatic recommendation to switch.

It’s an enrollment opportunity.

You still need to compare coverage.

---

What Is Changing With Medicare Star Ratings for 2027?

CMS finalized several changes affecting the Star Ratings program.

For the 2027 Star Ratings, CMS says it will not implement the Excellent Health Outcomes for All reward, previously referred to as the Health Equity Index reward.

Instead, CMS will continue the historical reward factor designed to encourage consistently high performance across quality measures.

CMS is also streamlining the measure set by removing 11 measures focused on administrative processes and areas where plan performance provided little meaningful distinction to consumers.

CMS describes the broader direction as focusing Star Ratings more heavily on:

• Clinical care
• Outcomes
• Patient experience

where meaningful differences exist between contracts.

That makes Star Ratings worth paying attention to.

It still doesn’t make them personalized recommendations.

---

Another Important Detail: Ratings Aren’t Necessarily Plan-Brochure Beauty Contests

The Star Ratings methodology is much more complicated than:

“People liked this plan, so CMS gave it five stars.”

CMS uses multiple measures, weighting categories, thresholds and methodology to determine ratings.

For 2027, published measures include areas involving:

• Member complaints
• Members choosing to leave
• Health plan quality improvement
• Drug plan quality improvement
• Getting needed prescription drugs
• Medication adherence
• Patient experience
• Clinical outcomes
• Access.

So the rating deserves respect.

Just don’t ask it to answer questions it wasn’t designed to answer.

---

What Star Ratings CAN Tell You vs. What They CAN’T

Star Ratings Can Help Tell You	Star Ratings Can’t Personally Tell You
Overall quality/performance	Whether your doctor participates
Member experience measures	Whether your cardiologist participates
Complaint-related performance	Whether your hospital is your preferred option
Certain clinical quality measures	Whether your exact medications fit well
Prescription-quality measures	Your personal annual drug costs
Access-related measures	Whether HMO or PPO fits your lifestyle
Quality improvement	Whether an OTC benefit matters to you
Comparative quality information	Which plan is personally “best”

This is probably the most important chart in the article.

---

What About a 3-Star Plan?

Don’t panic simply because you see:

⭐⭐⭐

A rating should trigger investigation rather than an emotional reaction.

Ask:

Why does the plan have that rating?

Which individual measures are stronger?

Which are weaker?

Does that weakness matter to me?

Are there higher-rated alternatives that also fit my healthcare?

You can examine quality information through Medicare’s official plan comparison resources.

---

What About Plans With No Star Rating?

Sometimes you may encounter a plan without a traditional overall rating—for example, depending on circumstances involving newer contracts or insufficient data.

Don’t automatically interpret:

No rating

as:

Bad plan.

Instead, recognize that you have less historical quality information available from the Star Rating system and evaluate the other plan characteristics carefully.

---

Don’t Compare Carriers Only by Stars Either

Another mistake is saying:

“Carrier X has five stars, therefore Carrier X is better than Carrier Y.”

Medicare plan availability and ratings can be tied to specific contracts and markets.

So when you’re reviewing carrier options, compare the actual plans available where you live, not simply the national reputation of the insurance company.

That’s one reason we’re building detailed Medicare carrier resources alongside our Compare Medicare Plans resources.

A Simple Rule for Using Medicare Star Ratings

Remember this sentence:

Use stars to compare quality after you’ve checked whether the plan fits your healthcare.

Not:

“Ignore Star Ratings.”

And not:

“Always pick five stars.”

Instead:

Step 1:

Check your doctors.

Step 2:

Check your prescriptions.

Step 3:

Check hospitals.

Step 4:

Compare healthcare costs.

Step 5:

Understand the network and plan rules.

Step 6:

Review Star Ratings.

Step 7:

Compare supplemental benefits.

Then make the decision based on the whole picture.

---

Should a 5-Star Medicare Plan Automatically Win?

No.

A 5-Star rating is a strong quality signal.

It deserves consideration.

But it doesn’t know:

your doctors.

your prescriptions.

your hospital.

your budget.

your travel habits.

your healthcare priorities.

your preferred plan structure.

That’s why there is no single rating that replaces an individualized Medicare comparison.

---

Frequently Asked Questions

What are Medicare Star Ratings?

Medicare Star Ratings are CMS quality ratings for Medicare Advantage and Part D plans. CMS publishes the ratings annually to help beneficiaries compare plan quality and performance.

What is the highest Medicare Star Rating?

Five stars is the highest overall Medicare Star Rating.

Does a 5-Star Medicare Advantage plan mean it’s the best plan for me?

Not necessarily. A 5-Star rating indicates strong quality performance, but it doesn’t determine whether your doctors participate, your prescriptions fit the formulary, your preferred hospital is accessible or the plan’s costs fit your needs.

Should I choose a 5-Star plan over a 4-Star plan?

Not automatically. Compare provider networks, prescriptions, costs, plan type, MOOP, benefits and other personal considerations alongside the Star Ratings.

What do Medicare Star Ratings measure?

CMS uses multiple quality and performance measures involving areas such as outcomes, process, patient experience, access and intermediate outcomes.

Can I switch to a 5-Star Medicare plan outside Open Enrollment?

Potentially. Medicare has a 5-Star Special Enrollment Period for beneficiaries with an eligible 5-Star plan available in their area. Medicare says this opportunity can generally be used once between December 8 and November 30 of the following year.

Does a 5-Star Special Enrollment Period mean I should switch?

No. It provides an enrollment opportunity; it isn’t a recommendation. Review doctors, prescriptions, costs and the type of coverage before changing plans.

Where can I check Medicare Star Ratings?

Medicare beneficiaries can compare available plans and quality ratings through the official Medicare Plan Finder.

Compare plans at Medicare.gov

Can Medicare Plan Assistance help me compare Star Ratings?

Yes. Medicare Plan Assistance can help you consider Star Ratings alongside provider networks, prescriptions, healthcare costs and other plan characteristics. Call (561) 808-9410.
