Medicare Advantage Star Ratings: Lawsuits Challenge CMS Recalculations (2026)

In the world of healthcare, where every decision can have far-reaching consequences, the legal battles between insurance providers and government agencies are not just about money; they're about principles, fairness, and the very future of healthcare systems. The recent lawsuits filed by SCAN Health Plan, Alignment Healthcare, and Elevance Health against the Centers for Medicare & Medicaid Services (CMS) over the recalculation of Medicare Advantage star ratings exemplify this complex dynamic. These cases are not merely about financial gains or losses; they're about the integrity of the healthcare system and the trust between providers and patients.

The Star Ratings Conundrum

The star ratings system, designed to assess the quality of Medicare Advantage plans, has been a double-edged sword. On one hand, it provides consumers with a clear metric to compare plans. On the other, it has been a source of contention, with providers arguing that the methodology is flawed and the results are unfair. The CMS's decision to recalculate the 2026 star ratings following a court victory for Clover Health has further exacerbated this tension.

SCAN Health Plan's Argument

SCAN Health Plan's lawsuit is a case in point. They argue that the CMS only partially applied the results of a court decision in favor of Clover Health. The Georgia judge's ruling vacated a set of 10 measures, arguing that CMS had exceeded its statutory authority in implementing them. However, SCAN claims that when scores for insurers other than Clover Health were recalculated, CMS only excluded the first set of measures, leaving the second set intact. This, they argue, is a violation of governing law.

"Respectfully, CMS’s decision to determine SCAN’s 2026 Star Rating without applying the Southern District of Georgia’s second holding violates governing law," the complaint reads. This statement encapsulates the essence of SCAN's argument: they believe the CMS has not been consistent in its application of the court's ruling, which undermines the fairness and integrity of the star ratings system.

Alignment Healthcare's Perspective

Alignment Healthcare's lawsuit, filed July 10, takes a slightly different but equally compelling angle. They argue that CMS's failure to adhere to the Georgia court's decision in full for other payers "deprives" the company of more than $50 million payments and "imposes significant reputational and competitive harms." This perspective highlights the financial and competitive implications of the CMS's decision, showing how it can have a profound impact on providers' operations and market standing.

Elevance Health's Legal Battle

Elevance Health's lawsuit, filed last week in a Georgia court, is a powerful testament to the principle of equity. They argue that CMS refused to recalculate their scores with the same methodology that was applied to Clover Health, despite being negatively impacted by the same measures. Elevance estimates that if they were given the same adjustments as Clover, they would see $115 million more in quality bonus payments. This financial disparity, they argue, is a direct result of CMS's selective application of the court's ruling.

"By giving Clover a recalculated, more favorable Star Rating while refusing to extend that same recalculation to Elevance, CMS has directly disadvantaged Elevance in markets where the two MAOs compete for the same Medicare beneficiaries," Elevance said in the lawsuit. This statement underscores the competitive imbalance created by the CMS's decision, highlighting how it can distort market dynamics and undermine the principle of fair competition.

Broader Implications and Future Developments

These lawsuits have broader implications for the healthcare industry. They raise questions about the transparency and consistency of the star ratings system, and the role of regulatory bodies in ensuring fairness and equity. The CMS's decision to recalculate scores based on a court ruling has set a precedent, and how this is applied in the future will be crucial. Will the CMS be more consistent in its application of court rulings, or will this remain a case-by-case basis? The outcome of these lawsuits will not only impact the providers involved but also shape the future of the star ratings system and, by extension, the healthcare landscape.

Personal Reflection

From my perspective, these lawsuits are a wake-up call for the healthcare industry. They highlight the need for a more transparent and consistent approach to the star ratings system. The CMS's decision to recalculate scores based on a court ruling is a step in the right direction, but it must be applied uniformly. The financial and competitive implications of these decisions cannot be overlooked, as they have a profound impact on providers' operations and market standing. The future of the star ratings system and, by extension, the healthcare landscape, depends on how these issues are resolved.

In conclusion, the legal battles between SCAN Health Plan, Alignment Healthcare, and Elevance Health against the CMS are not just about money; they're about the principles of fairness, equity, and transparency. The outcome of these lawsuits will shape the future of the star ratings system and, by extension, the healthcare landscape. As an expert commentator, I believe that these cases are a crucial moment for the industry, and the resolution will have far-reaching implications for providers, patients, and the healthcare system as a whole.
