The shares of the US health insurer fell, responding to the Trump Administration’s proposed Medicare Advantage Plans for 2027. According to the Centers for Medicare and Medicaid Services (CMS), payments will increase by an average of 0.09% to private issuers.
Shares of major health insurers, including UnitedHealth (UNH), CVS Health, and Humana (HUM), witnessed a significant decline in stock price. They went down between 8% and 13% in after-hours trading, while the shares of Elevance Health (ELV), Centene Corporation (CNC), and Molina Healthcare (MOH) went down by 5%. The government defended that the update will reflect underlying cost trends in 2026, like quality ratings and alteration of the risk adjustment models, where insurers will be paid more when their patients are sicker.
Revamp and the Triggered Concerns
The government expects that this slight increase will result in more than $700 million in additional payments in 2027. Mehmet Oz, CMS administrator, said in the press release that the proposal is aimed at modernizing the risk adjustments and also ensuring that the taxpayers are protected from unnecessary spending. He also added that, “These proposed payment policies are about making sure Medicare Advantage works better for the people it serves.” CMS has also reported that it is looking forward to cutting off the moneymaking industry billing practice, thereby aiming to improve payment accuracy.
Medicare Advantage is a key revenue generator for large health insurers, hence even a minor change in payment rates can have a great impact on profits. Therefore, the near-flat increase raises concerns that insurers may face struggles to offset rising medical and labor costs in the years ahead. As a result, the CMS plan suggests a slow payment growth in 2027, weighing on the sector. But this uncertainty has further added to the concerns about margin pressure, specifically for insurers who are majorly exposed to Medicare Advantage Plans. Medicare Advantage is a privately run health insurance plan that is contracted by Medicare. More than half of the Medicare beneficiaries are enrolled in such plans, which are enticed by lower monthly premiums and extra benefits that are not covered in traditional Medicare.
UnitedHealth is planning to report its fourth-quarter earnings today. Kevin Gade, chief operating officer of Bahl and Gaynor, a shareholder of UnitedHealth, said that they are looking forward to hearing from the CEO of UnitedHealth, Stephen Hemsley, about the impact of the proposal rates. The payment rates usually determine how much insurers can charge for monthly premiums, the plan benefits they offer, and ultimately their profits. CMS typically finalizes the Medicare Advantage rates in early April, implying that there is a chance for an increase in the coming months.
What Investors Must Expect
Looking forward, insurer stocks might remain volatile as investors wait for more updates and clarity on the final Medicare rates and how companies plan to manage costs. Any sign of higher or lower medical expenses and guidance can keep pressuring the group.
