UnitedHealth Faces Profit Shock After Medicare Changes
20 Apr
Summary
- Medicare payment changes cost UnitedHealth billions, impacting profits.
- The company is cutting costs and shedding members to offset losses.
- Optum Health division faces a significant threat from payment reforms.

UnitedHealth Group's financial performance is being significantly affected by Medicare payment adjustments enacted three years ago. These changes, designed by US regulators to ensure more accurate insurer payments, have resulted in billions of dollars in lost revenue for UnitedHealth, with an additional $6 billion expected in 2026. The full impact became apparent last year when the company drastically reduced its financial outlook, alarming the market.
In response, UnitedHealth executives are implementing cost-cutting measures and renegotiating contracts. This strategy includes reducing the number of people enrolled in its insurance plans and selling off medical clinics within the Optum Health division. The upcoming first-quarter report will reveal the extent of these adjustments and potential future surprises for shareholders.
The Centers for Medicare and Medicaid Services reworked a system called risk adjustment, which compensates insurers more for treating sicker patients in private Medicare Advantage plans. This shift means insurers are no longer reimbursed for numerous diagnoses, creating profitability challenges under the new rules.
UnitedHealth, the largest provider of Medicare Advantage plans with over 8 million members, is disproportionately affected due to its members' higher risk scores. However, analysts anticipate margin improvements this year. The company also received some relief as Medicare delayed further payment changes proposed for next year.
The payment overhaul poses a substantial risk to the Optum Health division, a network of medical providers largely focused on Medicare patients. This division, once a growth engine, swung to a loss last year. Executives are now concentrating on Optum Health's strongest markets, reducing its external doctor network, and minimizing financial risk exposure.
When the Biden administration first proposed these risk adjustment changes in 2023, UnitedHealth warned of significant payment reductions to its doctors. Despite initial assurances of being well-equipped to adapt, the company's financial performance faltered by its first quarter 2025 report, leading to a dramatic stock price drop.
