2026 Appeals and the Battle Over $3 Billion in Bonus Payments
As of March 2026, a high-stakes legal confrontation between Humana Inc. and the Centers for Medicare & Medicaid Services (CMS) is reaching a critical phase in the federal appellate courts. At the center of the dispute is a dramatic downgrade in Humana’s “Star Ratings” for the 2025 plan year, a move that analysts estimate could strip the insurer of approximately $3 billion in quality bonus payments. Following a series of losses in lower courts throughout 2025, Humana has elevated its challenge to the U.S. Court of Appeals for the Fifth Circuit, arguing that the government’s rating methodology is “arbitrary, capricious, and unlawful.”
The Catalyst: From 4.5 Stars to 3.5 Stars
The legal firestorm began in late 2024 when CMS released its annual Star Ratings, which serve as a primary metric for plan quality and a gateway to lucrative federal bonuses. Humana, the second-largest provider of Medicare Advantage (MA) plans in the United States, saw its flagship contracts plummet from a 4.5-star rating to 3.5 stars. This downgrade meant that the percentage of Humana members enrolled in plans with four stars or higher dropped from a robust 94% in 2024 to just 25% for the 2025 plan year.
The financial stakes are massive. Under the Medicare Advantage program, plans rated four stars or higher receive significantly higher per-member payments from the federal government. These “bonuses” are typically used by insurers to offer extra benefits, such as dental and vision coverage, or to lower monthly premiums. For Humana, the loss of these funds threatens its competitive edge and has placed immense pressure on its profit margins entering 2026.
The “Secret Shopper” Controversy
In its March 2026 appellate filings, Humana focused heavily on the specific metrics that led to the downgrade. The insurer alleges that its scores were unfairly suppressed due to three “test calls” conducted by CMS “secret shoppers” to evaluate foreign-language interpreter services. According to the lawsuit:
- Technical Failures: Humana claims two of the three calls were dropped due to technical issues on the caller’s end, rather than a failure by the Humana representative.
- No-Callback Policy: The insurer argued that CMS’s refusal to allow for a callback or a re-test after a technical glitch was a violation of the agency’s own procedural fairness regulations.
- Data Transparency: Humana continues to allege that CMS has withheld “critical score-validation data” that would allow the insurer to verify the accuracy of the government’s calculations.
While industry leaders like UnitedHealthcare successfully sued to have their ratings recalculated in 2025, Humana has found less success. In October 2025, U.S. District Judge Reed O’Connor dismissed Humana’s case with prejudice, ruling that the CMS “no-callbacks” policy was consistent with federal law and not an “arbitrary” exercise of power.
2026 Status: The Fifth Circuit Appeal and 2026 Ratings
As of March 18, 2026, the legal battle has moved to the conservative-leaning Fifth Circuit in New Orleans. Humana is seeking a full reversal of the lower court’s decision, hoping to force a retroactive recalculation of its 2025 bonuses. However, the company has already been forced to move forward with its 2026 business strategy under the assumption that the lower ratings will stand. Early data for the 2026 plan year indicates that only 20% of Humana members are currently in plans rated 4 stars or higher, a further decline from the previous year.
The impact is already being felt by beneficiaries. In response to the reduced federal funding, Humana executives confirmed in an October 2025 investor call that the company has begun “tightening operations,” which in some markets has resulted in higher out-of-pocket costs or reduced “extra” benefits for seniors. This “trickle-down” effect of the bonus cuts is a primary concern for consumer advocacy groups who fear that the battle between insurers and regulators is ultimately harming patient care.
Legal Parallels in Corporate Accountability
The Humana case highlights the extreme sensitivity of performance-based contracts in the healthcare sector. Similar to how integrated design and construction models rely on precise milestones to trigger payments, the Medicare Advantage program uses Star Ratings as a “digital milestone” for billions in taxpayer dollars. Furthermore, as insurers shift their internal policies to compensate for lower revenues, staying updated on employment law updates for 2026 is essential for the thousands of healthcare workers and administrators affected by corporate restructuring.
Future Outlook: Will CMS Pivot?
While Humana fights in court, the regulatory landscape is shifting. In late 2025, the administration proposed new rules that would eliminate several “call center” metrics—the very metrics at the heart of Humana’s lawsuit—citing them as unnecessary and prone to error. While this may help Humana in the future, it does not solve the immediate multi-billion dollar hole in their 2025 and 2026 budgets.
Key Developments to Watch in 2026:
- The Fifth Circuit Decision: A ruling is expected by the summer of 2026. A win for Humana would be a major upset and could trigger a wave of retroactive payments across the industry.
- Member Retention: With reduced benefits in some 3.5-star plans, the upcoming 2027 enrollment period (beginning in October 2026) will be a critical test of member loyalty.
- Contract Diversification: Humana is currently moving members into its few remaining 4-star contracts to mitigate the financial damage, a strategy known as “plan consolidation.”
