Shares of major U.S. health insurers climbed in early trading on Tuesday following a government announcement that will raise payment rates for Medicare Advantage plans in 2027 by more than initially proposed.
UnitedHealth surged 6.9% in premarket activity. CVS Health, Elevance Health, Centene and Molina Healthcare each rose in a range between 3.6% and 6%. Humana led gains among S&P 500 components, jumping 10.7% and becoming the best-performing stock in the index early in the session.
The Centers for Medicare & Medicaid Services said late on Monday it will increase payments to private insurers that offer Medicare Advantage plans by an average of 2.48% for 2027. That change is considerably higher than the 0.09% boost CMS had proposed in January.
Analysts at RBC Capital Markets noted the adjustment is meaningfully above their prior expectations of 1% to 1.5% for the 2027 rate. Jefferies analysts framed the revision as a correction to past actuarial estimates rather than a retreat from CMS enforcement, writing: "We view the revision more as righting an actuarial wrong, not CMS backing off its disciplinarian attitude towards MA."
In addition to the rate revision, a Medicare agency official told reporters on a call that insurers will receive an additional 2.5% boost from a change to risk assessment payments tied to enrollees health status. Taken together, CMS said the increases amount to roughly a 5% uplift.
CMS estimated the higher payment rates will translate into more than $13 billion in additional payments to Medicare Advantage plans in 2027. The government payment rate plays a direct role in how insurers set monthly premiums, determine plan benefits and estimate profitability. Insurers also use the rate as a basis for preparing their bids for Medicare Advantage contracts they plan to sell for 2027.
The market moves came as investors reacted to the larger-than-expected funding change and the accompanying adjustment to risk scores, which together increase the revenue backdrop for companies active in the Medicare Advantage space.
