Quick Answer: In 2026, Medicare Advantage Star Ratings (ranging from 1 to 5 stars) measure clinical care quality, member satisfaction, and operational efficiency across plan contracts. While a 4-star or 5-star rating indicates superior clinical outcomes and qualifies plans for federal Quality Bonus Payments (QBPs), a high star rating does not guarantee that your personal doctors (e.g., Mount Sinai or NYU Langone in NYC) or specific prescriptions are covered at the lowest cost. New York beneficiaries should evaluate star ratings alongside local hospital network access, Part D formularies under the $2,000 out-of-pocket cap, and county-specific benefits.
Medicare Advantage plans can look similar at first glance, especially when premiums and benefits are close. One way Medicare helps beneficiaries compare plan quality is through its star rating system, which scores Medicare Advantage (Part C) and Prescription Drug (Part D) plans from 1 to 5 stars based on measures such as quality of care, member experience, customer service, and management of chronic conditions.
A higher star rating can be a useful sign of a plan’s overall performance, but it does not automatically mean that plan is the best fit for you. Star ratings cannot tell you whether your preferred primary care physician or hospital system (like Mount Sinai in Manhattan or Montefiore in The Bronx) is in-network, whether your prescriptions are affordable, or how much you may pay out of pocket during the year. Those details still need to be evaluated alongside the rating.
In this guide, reviewed by Life143’s licensed New York Medicare brokers and compliance specialists against the official CMS 2026 Part C & D Star Ratings Technical Notes, we explain how star ratings work, what CMS measures, what ratings can and cannot tell you, and how to evaluate them alongside New York-specific plan networks and costs. By the end, you will have a clearer understanding of how much weight to give a plan’s star rating when choosing your Medicare coverage.
How Do Different Medicare Advantage Star Ratings Compare?
Below is a breakdown of how CMS classifies star ratings, how ratings impact carrier funding, and what each tier means for New York Medicare beneficiaries:
| Star Rating Tier | CMS Benchmark Quality | Federal Bonus Eligibility (QBP) | Special Enrollment Rights (SEP) | Broker / Compliance Consideration |
|---|---|---|---|---|
| 5 Stars | Excellent Quality | Qualifies for 5% QBP & higher rebate tiers | Year-Round 5-Star SEP (Dec 8 – Nov 30) | Rare (21 contracts nationwide). Verify NYC network before switching outside AEP. |
| 4 to 4.5 Stars | Above Average Quality | Qualifies for 5% Quality Bonus Payment | Standard Annual Enrollment (Oct 15 – Dec 7) | Represents ~63.5% of enrollees. Strong sweet spot for local network & benefits. |
| 3 to 3.5 Stars | Average Quality | No Federal Bonus Funding | Standard Annual Enrollment (Oct 15 – Dec 7) | May face margin pressure; double-check supplemental benefits for annual cuts. |
| Below 3 Stars / Flagged | Below Average / Poor | No Funding / CMS Sanction Risks | Special Disenrollment SEP if low-rated 3+ yrs | Flagged with CMS Low-Performing Icon. Avoid unless no local alternative exists. |

What Are Medicare Advantage Star Ratings?
A Medicare Advantage star rating is a score from 1 to 5 stars that the Centers for Medicare & Medicaid Services (CMS) assigns to each plan contract every year. Half-star increments exist too, so you will see ratings like 3.5 or 4.5 stars.
Quick definition: CMS is the federal agency that runs the Medicare program. Each fall, it evaluates every Medicare Advantage contract and publishes a star rating reflecting how well that plan performed on quality and service measures during the prior measurement period.
The rating exists to give Medicare beneficiaries an objective, standardized benchmark to compare plan quality and clinical performance, counterbalancing carrier marketing materials during the Annual Enrollment Period (AEP).
Who Assigns the Ratings and Why?
CMS calculates these ratings independently of the insurers that sell the plans, releasing updated ratings every October, just ahead of the Annual Enrollment Period.
The ratings serve two distinct purposes:
- Consumer Comparison Tool: They give you an objective, standardized benchmark to gauge clinical quality across competing plans.
- Federal Quality Bonus Payments (QBPs): Ratings determine whether a plan qualifies for extra federal funding. Contracts rated 4 stars or higher receive a 5% benchmark bonus from CMS. Insurance carriers pass these funds to members through lower copays, extra dental/vision allowances, and zero-dollar monthly premiums. Plans rated under 4 stars lose this funding.
How Does the Star Rating System for Medicare Advantage Plans Work?
The star rating system for Medicare Advantage plans rests on dozens of individual measures that CMS rolls up into one overall score, like a report card with many subjects averaged into a single grade.
CMS currently rates MA-PD contracts (Medicare Advantage plans with drug coverage) on up to 40+ measures, MA-only contracts on up to 33 measures, and standalone Part D plans on up to 12 measures.
Those measures fall into key broad categories:
- Outcomes: How well a plan manages chronic conditions like diabetes, kidney health, and cardiovascular disease.
- Intermediate Outcomes: Clinical benchmarks like blood sugar (HbA1c) and blood pressure control.
- Process Measures: Preventive care tracking, covering screenings, mammograms, and flu shots.
- Patient Experience: Member feedback gathered through official CAHPS survey questionnaires.
- Access & Service: How easily members get appointments resolved, administrative appeals, and call center responsiveness.

What Does CMS Actually Measure?
You do not need to memorize all 40-plus individual measures to use the rating well. What matters is understanding that the score blends clinical quality, how members say they were treated, and how responsive customer service tends to be.
Because CMS averages up to 45 individual measures across Part C and Part D, including chronic care management, preventive screenings, and prescription adherence, a plan can score 5 stars in customer service while struggling in clinical care management, or vice versa.
Why Does This Year’s Rating Reflect Last Year’s Care?
Here is a detail many people miss: The star rating you see in 2026 is based on an earlier measurement period, not on what the plan is doing right now.
Think of it like a restaurant health inspection score posted on the door. It tells you how the kitchen performed on inspection day, not what is happening this exact minute. A high rating is a strong signal about past performance, not a live guarantee of your future experience.
What Changes Affected Medicare Advantage Star Ratings for 2026?
If you compared plans last year, you will notice some ratings shifted, and the reasons are worth understanding before you draw conclusions.
According to official CMS data, the unweighted national average star rating for Medicare Advantage plans with drug coverage (MA-PD) is 3.65 in 2026 (3.99 enrollment-weighted average). Approximately 63.5% of MA-PD enrollees are enrolled in a plan rated 4 stars or higher for 2026, qualifying those contracts for federal Quality Bonus Payments (QBPs) that fund local supplemental benefits.
The main driver behind this shift was a CMS rule change. The agency reduced the weight given to patient experience, complaints, and access measures, cutting their influence from a weight of 4 down to 2, while increasing emphasis on clinical outcome measures. CMS also removed several measures from the scoring model and reverted to a more generous bonus reward system.
Supporters note this shift refocuses ratings on concrete health outcomes, such as blood sugar control and kidney health evaluations. Critics emphasize that reducing member feedback weights (from 4x down to 2x) makes it harder for consumers to gauge day-to-day administrative hurdles, even as top-performing plans secure lucrative federal Quality Bonus Payments (QBPs).
Looking ahead, CMS finalized further changes for the 2027 rating cycle in April 2026, including the removal of 11 more administrative measures. That signals the methodology will keep evolving, so a rating change from one year to the next does not always mean a plan’s actual care changed. Sometimes the ruler itself got adjusted.
Do Medicare Advantage Plans’ Star Ratings Actually Matter When Choosing a Plan?
Yes, star ratings matter, but they work best as one input among several, not as the only factor you weigh.
Real-Life New York Broker Scenario:
Consider a Brooklyn beneficiary comparing two HMO options: Plan A ($0 premium, 3.5 stars) and Plan B ($42 premium, 4.5 stars).
While Plan B’s 4.5-star rating reflects superior chronic care management (such as diabetes HbA1c control), it carries a narrower provider network that excludes Maimonides Medical Center and NYU Langone Brooklyn. If your cardiologist is at NYU Langone, Plan B’s 4.5-star quality score won’t cover your out-of-network claims. Furthermore, while both plans adhere to the federal $2,000 Part D out-of-pocket prescription cap, Plan A places brand-name insulin on Tier 2 ($15 copay), while Plan B requires Tier 3 ($45 copay) prior to hitting the cap.
We’ve found that many people assume a high star rating guarantees their doctor is covered or their drugs will be cheap. It does not work that way. The rating measures the plan’s performance across its entire member population, not your individual situation.
What the Rating Tells You vs. What It Doesn’t
| What the Rating Tells You | What the Rating Doesn’t Tell You |
|---|---|
| How members rate their overall experience and satisfaction | Whether your doctors and specialists are in network |
| How well the plan manages chronic conditions and preventive care | Whether your prescriptions are covered at a low cost |
| How responsive customer service tends to be | What your exact out-of-pocket costs will be |
| Whether the plan has a history of member complaints | How the plan will perform this year, since the score reflects past data |
What Medicare Advantage Plans Have a 5-Star Rating in 2026?
Earning a 5-star rating requires top-tier performance across nearly all metrics, making 5-star plans exceptionally rare nationwide—accounting for approximately 2.3% of total MA-PD enrollment.
For the 2026 plan year, exactly 21 contracts nationwide earned the full 5-star rating: 18 Medicare Advantage drug plans, 1 Cost plan, and 2 standalone Part D prescription drug plans (PDPs).
We are not listing specific carrier names here, and there is a good reason. Star ratings apply at the contract level, and one insurance company can operate multiple contracts with different ratings in different counties. A plan rated 5 stars in one part of the country—or even in Upstate NY—may not have the same rating or network in Queens, The Bronx, Manhattan, Brooklyn, or Staten Island.
The most reliable way to find current 5-star options where you live is the Medicare Plan Finder tool on Medicare.gov. Enter your ZIP code, and it shows every plan available in your area with its current rating.
On the other end, CMS flagged 4 contracts nationwide with a low-performing icon in 2026 for consistently weak ratings, down from 6 the year before. That icon deserves just as much attention as the 5-star badge.
How Can You Check and Use Star Ratings When Comparing Plans?
Here is a short process you can follow whenever you evaluate your options:
- Open the Plan Finder tool on Medicare.gov
- Enter your NY ZIP code and review every plan available in your county.
- Compare each plan’s rating alongside its premium, deductible, and whether your doctors and prescriptions are covered.
- Note whether any plan carries a low-performing icon, and treat that as a caution flag.
One key rule for beneficiaries: if a 5-star plan is available in your New York county, you can use the 5-Star Special Enrollment Period (SEP) to switch into it once between December 8 and November 30 of the following year. However, New York residents should verify provider network continuity and hospital access (such as Montefiore, Mount Sinai, or NYU Langone) before switching outside of AEP.
Licensed NY Broker Compliance Note: Medicare Advantage vs. Medigap in New York State
Unlike most states, New York law enforces continuous Community Rating and year-round Guaranteed Issue for Medicare Supplement (Medigap) plans. This means NY beneficiaries can switch Medigap policies at any time during the year without medical underwriting. If a Medicare Advantage plan’s star rating drops or its provider network contracts (e.g., losing access to a major NYC hospital system), New York residents have unique protections when transitioning back to Original Medicare plus Medigap compared to beneficiaries in other states.
Should You Compare Medicare Advantage Plans Beyond the Star Rating?
Yes. Medicare Advantage star ratings can be helpful when comparing plans, but they should not be the only factor in your decision. A high-rated plan may still have provider network limits, prescription drug costs, premiums, deductibles, or out-of-pocket expenses that do not match your healthcare needs.
The right plan depends on your doctors, prescriptions, pharmacy, budget, county, health conditions, and whether the plan’s benefits support the care you actually use. Reviewing star ratings alongside coverage details can help you avoid choosing a plan based on quality scores alone.
