The $120 Million Shift: Why CMS is Recalculating Medicare Advantage Star Ratings and What it Means for Your 2027 Healthcare
The $120 Million Shift: Why CMS is Recalculating Medicare Advantage Star Ratings and What it Means for Your 2027 Healthcare
The federal government’s Medicare Advantage program just hit another massive legal speed bump. In an unprecedented but increasingly familiar script, the Centers for Medicare & Medicaid Services (CMS) officially informed health insurance plans that it is voluntarily recalculating certain 2026 Star Ratings—a move that directly impacts billions of dollars in federal Quality Bonus Payments for the 2027 plan year.
For the third consecutive year, a private insurer has successfully taken the federal government to court over the math used to grade health plans, forcing regulators back to the drawing board. Here is what triggered this sudden shift and how it will ripple across the Medicare Advantage landscape for 2027.
The Spark: Clover Health’s Legal Victory
The catalyst for this sudden recalculation belongs to Clover Insurance Co. v. HHS, a lawsuit decided by a federal judge. Clover Health sued the Department of Health and Human Services (HHS) and CMS after its premier Medicare Advantage plan dropped from a 4-star rating to a 3.5-star rating.
In the world of Medicare Advantage, that half-star drop is a financial cliff. Reaching the 4-star threshold unlocks massive, lucrative federal Quality Bonus Payments. Clover estimated that missing the cut-off would cost them roughly $120 million in funding.
Clover argued that CMS violated the law by factoring in 20 invalid performance metrics. The federal judge agreed, ruling that:
- 10 measures relied on data sources that CMS did not have explicit statutory authority from Congress to collect.
- 10 measures were implemented without going through the legally mandated public notice-and-comment rulemaking channels.
The court ordered CMS to strip out the invalid metrics and rerun Clover’s scores. Almost immediately, Clover announced its contracts bounced all the way up to 4.5 Stars for the 2027 payment year.
Why CMS is Rerunning the Numbers for Everyone (With a Catch)
Instead of waiting for dozens of copycat lawsuits from other insurance giants like UnitedHealthcare or Elevance, CMS sent a memo to health plans announcing a proactive, nationwide recalculation. However, regulators are protecting themselves—and the insurers—with two critical stipulations:
- Only Upside for Insurers: CMS stated that it will only adjust a rating if the recalculation results in a higher score. No health plan will see its star rating dropped as a result of this review.
- A “Targeted” Fix: Rather than completely throwing out all 20 of the challenged elements used in Clover’s specific case for everyone, CMS is only pulling the specific measures it acknowledges it lacked explicit permission to collect under the law.
Because of this targeted approach, early industry analysis suggests that the recalculation won’t radically shift the average star rating industry-wide. It is a highly specific remedy rather than a universal “freebie” upgrade for the sector.
How This Affects 2027 Medicare Advantage Plans
While this is fundamentally a battle over regulatory bureaucracy and corporate balance sheets, the ripple effects will be felt directly by everyday Americans choosing health coverage for 2027.
1. More Stable (and Extra) Benefits for Certain Plans
When a plan gets upgraded—like Clover’s jump to 4.5 stars—it receives a massive influx of federal bonus cash. By law, insurers must use a portion of these Quality Bonus Payments to fund “supplemental benefits.” This means plans that win an upgrade will suddenly have more capital to offer lower copays, expanded dental, vision, and hearing coverage, or lower monthly premiums for the 2027 contract year.
2. A Mad Rush to Resubmit 2027 Bids
The timing of this ruling has thrown insurance executives into chaos. Bids for the 2027 plan year were already calculated based on the old star ratings. CMS has given upgraded plans an incredibly tight window—until June 22, 2026—to formally state their intent to resubmit their 2027 market bids using the new math.
3. A Precedent for Future Legal Warfare
This ruling proves that the legal ground beneath Medicare Advantage is shifting. Previously, insurers won lawsuits based on minor computational errors (like the timing of customer service phone calls). Clover successfully attacked the legality of the metrics themselves. Major insurers are already evaluating whether CMS’s specific method of recalculation leaves room for immediate follow-up lawsuits before the next official round of annual star ratings drops in October.
The Bottom Line
For seniors and eligible beneficiaries planning out their 2027 healthcare needs, this means the landscape will be highly competitive. When the annual open enrollment period arrives in the fall, look closely at the star ratings and the accompanying extra benefits. Thanks to a single federal court case, some plans will enter the 2027 market with millions of dollars in unexpected bonus funding to win your business.
