CMS Raises the Bar for 2027 Medicare Advantage Star Ratings

CMS Tightens the Grading Curve for 2027 Medicare Advantage Plans

The Centers for Medicare & Medicaid Services (CMS), the federal agency that administers Medicare and sets the annual Star Ratings for Medicare Advantage and Part D plans, sent insurers draft 2027 Star Ratings and the underlying scoring thresholds this week, according to a Sept. 10, 2026 report from Healthcare Dive. The Star Ratings program scores plans from one to five stars on measures such as customer service, chronic disease management, and member satisfaction, and CMS uses "cutpoints," the minimum score needed to reach each star level, to turn raw performance data into a letter-grade-style score. Healthcare Dive reported that the draft cutpoints for roughly half of the measures moved higher for 2027, meaning plans will need to perform better than they did in prior years just to hold the same star level they had before. One Medicare Advantage industry expert cited in the report said the stricter grading "doesn't bode well" for insurers heading into the next ratings cycle.

Star Ratings matter to enrollees because they appear directly on Medicare's Plan Finder tool and determine which plans qualify for extra federal funding that pays for richer benefits.

Why Cutpoints Decide Who Gets a Quality Bonus

Medicare Advantage plans that score four stars or higher qualify for CMS quality bonus payments (QBPs), extra federal dollars added to a plan's payment benchmark that insurers can use for lower premiums, reduced cost-sharing, or added benefits like dental and vision coverage. Because Star Ratings are graded on a relative curve across the industry rather than a fixed pass or fail score, raising cutpoints means a plan that improved its own performance can still lose stars if its gains didn't keep pace with the new, higher bar. A plan that held 4.5 stars in 2026 could fall to four stars or lower for 2027 without changing anything about how it operates, simply because CMS raised what counts as good on a given measure.

CMS typically finalizes and publishes Star Ratings each October, shortly before the Medicare Advantage Annual Enrollment Period opens, so the numbers insurers just received in draft form are expected to become the ratings seniors see on Medicare Plan Finder this fall when they shop for 2027 coverage.

What This Means for Insurers, and Indirectly for You

Medicare Advantage insurers rely on quality bonus payments as a significant source of revenue, so a broad increase in cutpoints across the industry can pressure insurer margins for the 2027 plan year. When margins tighten, insurers have historically responded in later years by narrowing provider networks, raising cost-sharing, or trimming supplemental benefits rather than raising premiums outright, since a premium increase is more visible to shoppers comparing plans during enrollment. Healthcare Dive's report did not specify which insurers or which individual measures saw the steepest cutpoint increases, so it remains unclear which companies and plans will feel the biggest effect. Readers should treat any single insurer's 2027 benefit design as unconfirmed until that insurer's own Annual Notice of Change or CMS's final Star Ratings data is published this fall.

What Higher Cutpoints Could Mean for Your 2027 Options

Fewer four-star and five-star Medicare Advantage plans in a given county could mean fewer plans offering the extra benefits that quality bonus payments fund, since insurers that lose bonus-eligible status may scale back perks rather than absorb the cost. Readers who chose their current plan largely for extras like a dental allowance, an over-the-counter card, or a fitness benefit should watch their plan's Annual Notice of Change (ANOC), typically mailed each September, for any reduction tied to a rating change.

Practical steps for the 2027 enrollment season:

• Read your current plan's ANOC closely rather than assuming your coverage and benefits carry over unchanged into 2027.
• Compare final 2027 Star Ratings on Medicare Plan Finder once CMS publishes them this fall, and check the specific measures behind the overall score rather than just the headline star count.
• Weigh any rating drop against the benefits and network you actually use. A plan that fell from five stars to four may still serve you better than a higher-rated plan with a narrower network or a different drug list.
• Contact a licensed Medicare agent or your State Health Insurance Assistance Program (SHIP) for help interpreting how a rating change affects your specific plan's 2027 costs and benefits.

The Medicare Advantage Annual Enrollment Period for 2027 coverage runs Oct. 15 through Dec. 7, 2026, giving readers a defined window to review changes once CMS releases final ratings.
