The Trump administration’s Medicare policy this year has paired tougher oversight language with a significant funding increase for private insurers that run Medicare Advantage plans. The shift came into focus on April 7, 2025, when the Centers for Medicare & Medicaid Services finalized a much larger-than-expected payment update for 2026 plans after first signaling a far smaller increase.
CMS approved a larger 2026 payment increase after proposing much less
The Centers for Medicare & Medicaid Services said on April 7, 2025, that average payments to Medicare Advantage plans would rise 5.06% for calendar year 2026, a final rate that exceeded the government’s earlier proposal and lifted shares of major insurers including UnitedHealth, Humana and CVS Health, according to CMS and Reuters. CMS said the increase reflected an effective growth rate of 9.04%, higher than the 5.93% estimate in the January advance notice, with updated data affecting the final calculation.
That reversal mattered because the administration had initially pointed toward a much tighter increase. Reuters reported the January proposal implied a much smaller benchmark change, and investors treated the April notice as a clear win for insurers that depend heavily on Medicare Advantage revenue. CMS said the payment policy works alongside the agency’s separate final rule for Medicare Advantage and Part D issued on April 4, 2025.
The size of the program gives the decision national weight. Medicare Advantage is the privately run alternative to traditional Medicare, and payment changes influence premiums, supplemental benefits and insurer margins. CMS framed the April rate announcement as a routine annual update, but the gap between the preliminary and final numbers turned it into one of the most closely watched health insurance decisions of the spring.
This is not a state-by-state announcement tied to one local facility, employer or insurer office. The payment policy applies nationally to Medicare Advantage plans, which are sold county by county across the country by large carriers and regional insurers, so the practical effect for residents will show up through plan bids, benefits and pricing for the 2026 coverage year rather than through a single announced local change.
What is confirmed is the federal payment increase and the administration’s separate push to intensify oversight. On May 21, 2025, CMS said it would audit all eligible Medicare Advantage contracts each year and add nearly 2,000 coders in an effort to complete long-delayed reviews for payment years 2018 through 2024 by early 2026. CMS said those audits are aimed at testing whether diagnoses used to boost plan payments are supported by medical records.
What is not yet known is how each insurer will translate the higher rates into specific benefits or premiums in any given county. Insurers had not released a comprehensive nationwide list of 2026 plan designs when the rate notice was issued, and plan details for beneficiaries are typically finalized later in the annual bid and approval process.
The administration’s two-track approach grew out of a longstanding debate in Washington over whether Medicare Advantage insurers are paid too much because of aggressive diagnosis coding. CMS has said Risk Adjustment Data Validation audits are its primary tool to recover improper payments, and a 2023 final rule allowed the agency to extrapolate audit findings beginning with payment year 2018. The Government Accountability Office has also said stronger recovery efforts are needed because improper payments can reach hundreds of millions of dollars annually.
At the same time, insurers and their allies have argued that payment updates must keep pace with rising medical costs and utilization. CMS said the final 2026 rate was driven in part by updated fee-for-service Medicare spending data, which changed the growth calculation between the advance notice and the final announcement. That explanation helped define the April decision as a technical payment update, even as the financial impact clearly favored insurers.
For Medicare beneficiaries, the immediate takeaway is that federal regulators are trying to do two things at once: preserve insurer participation in a fast-growing private Medicare market while scrutinizing whether plans were overpaid in prior years. The next concrete changes for enrollees will come through 2026 plan offerings and through future audit recoveries, both of which CMS has said will continue under its current policy framework.
