CMS Star Ratings: Impact on Humana and Alignment Healthcare's Future
Shares of Humana surged by 16.5% after CMS announced updated Medicare Advantage Star Ratings, while Alignment Healthcare's shares plummeted over 20% due to their rating changes.
The Centers for Medicare & Medicaid Services (CMS) recently released their annual Medicare Advantage Star Ratings, causing significant market movements. Humana's largest Medicare Advantage contract saw a substantial improvement from 3.5 to 4 stars for the 2027 ratings. This upgrade not only re-establishes Humana's eligibility for federal quality bonus payments but also positively impacts its earnings potential for 2028. On the other hand, Alignment Healthcare faces challenges as its main California contract dropped from 4 stars to 3.5 stars, affecting approximately 81% of its membership as of September 2025.
Previously, Humana suffered a major decline in ratings in 2024, with members in 4-star or higher plans dropping from 94% to 25%, adversely affecting earnings forecasts. In contrast, Alignment once boasted all members in plans rated 4 stars or higher for 2026, marking it as a strong performer at the time. Medicare Advantage plans receive ratings from 1 to 5 stars based on clinical outcomes, customer experience, and plan performance. Achieving at least 4 stars makes contracts eligible for quality bonus payments, enhancing the funds available to insurers. The latest ratings will significantly influence insurer payments in 2028.
Understanding CMS Star Ratings
The CMS's Medicare Advantage Star Rating system is a pivotal determinant of insurer success. Plans are rated on a scale from 1 to 5 stars, with higher ratings offering competitive advantages. Insurers with high-rated plans can qualify for increased federal payments, boosting their revenue streams and providing incentives to improve service quality. A drop in star ratings can severely impact an insurer's financial performance and market standing.
- Humana's Gain: Largest contract improved to 4 stars, expanding federal bonus eligibility.
- Alignment's Drop: Key contract fell to 3.5 stars, affecting the majority of its membership.
- Financial Outlook: Ratings impact federal payments, affecting insurer forecasts for 2028.
Implications for Industry Professionals
For insurance agents, brokers, and underwriters, these shifts underline the critical importance of staying informed about CMS Star Ratings. Changes can influence coverage, claims, and underwriting decisions as insurers adjust strategies to meet rating criteria. Industry professionals should anticipate potential shifts in consumer preferences and prepare for changes in carrier offerings. Monitoring how insurers adapt to ratings will offer valuable insights for advising clients and aligning with successful carriers.
