Humana surges 15% after topping 2027 Medicare star ratings

Humana’s shares leapt 15% on Friday after the Centers for Medicare & Medicaid Services (CMS) announced its 2027 Medicare Advantage star ratings, with the insurer topping the charts. The jump follows a dramatic rise in the proportion of Humana’s members enrolled in plans rated four stars or higher – from 20% in 2026 to 95% for 2027 – a move that could unlock billions in quality‑bonus payments for the insurer.

The CMS announcement, released on Thursday, came after Humana’s press release on Friday. In the statement, chief executive Jim Rechtin said the insurer was “extremely proud” of the ratings, noting that 42% of members were in 4.5‑star plans and that the largest contract had moved from 3.5 to four stars. The uptick is a direct result of improvements in drug‑plan quality, health‑plan quality and readmission metrics, according to Evercore ISI analyst Elizabeth Anderson, who linked the rise to a potential $4.8 billion in bonus payments in 2028.

Humana’s performance is stark when set against its peers. J.P. Morgan had projected that 60% to 70% of Humana members would qualify for four‑star‑plus plans, a figure that the insurer now far exceeds. UnitedHealth’s share of members in such plans is expected to fall to 67% from 81%, while CVS Health is projected at 70% from 84%. The shift is reflected in the table below.

CMS’s new methodology for 2027 adds two medication‑safety measures and triples the weight of measures covering physical and mental health from one to three. These changes mean that a lower rating can result from altered scoring thresholds rather than a decline in care quality. As 24/7 Wall St. Notes, the overall number of Medicare Advantage contracts earning at least four stars fell by 18%, yet enrollment in such contracts rose from 67% to 71%.

For investors, the star ratings are more than a headline. CMS’s quality‑bonus program rewards plans rated four stars or higher, and the bonus payments are due in 2028. Analysts estimate that Humana’s improved ratings could translate into $4.8 billion of additional revenue. The upside depends on how the company reinvests the gains in member benefits and provider arrangements, a point highlighted by Baird analysts.

Beyond the financial implications, Humana’s rating gains are underpinned by tangible improvements in preventive care. The insurer reported that it met 663,000 more care opportunities and saw 534,000 additional members complete annual preventive visits compared with the previous year. Targeted outreach led to 28,000 members completing overdue mammograms, uncovering 600 breast cancers, and 93,000 undergoing colorectal screenings that identified 100 new precancers and cancers. An additional 73,000 members received overdue eye exams, revealing 17,000 previously undetected diabetes‑related eye diseases.

These metrics illustrate how Humana’s member‑engagement strategy translates into higher star ratings and potential financial upside. The company’s press release also highlighted that it now has 18 Medicare Advantage contracts rated at least four stars, up from seven in the prior year, and that its prescription‑drug plan earned a 4.5‑star rating.

Humana is not the only insurer feeling the impact of the new ratings. Alignment Healthcare’s shares fell 20% after its largest contract dropped from four to 3.5 stars, while Clover Health’s shares climbed 11% after its PPO plans earned five stars. The market’s reaction underscores the sensitivity of Medicare Advantage stocks to CMS scoring changes.

Looking ahead, the Medicare Advantage and Prescription Drug Plan Annual Enrollment Period (AEP) runs from October 15 to December 7, 2026, with coverage for selected plans taking effect on January 1, 2027. Humana’s improved ratings should enhance its appeal to beneficiaries during the AEP, potentially boosting enrollment.
