Millions of seniors enrolled in Medicare Advantage plans face a tighter market in 2027 after the Centers for Medicare & Medicaid Services proposed raising payments to insurers by just 0.09%, a net increase of about $700 million. CMS released the Advance Notice on January 26, 2026, setting off alarm among insurance brokers who say the near-flat payment growth will force carriers to pull out of more counties and cut supplemental benefits that seniors depend on, from dental coverage to gym memberships.
A 0.09% increase and why brokers say it threatens plan availability
The proposed payment update combined several moving parts: an effective growth rate reflecting rising healthcare costs, adjustments to risk model normalization, and new restrictions on which diagnosis sources insurers can use to justify higher per-patient payments. When CMS netted those factors together, the result was a projected 0.09% average increase across all Medicare Advantage contracts. For an industry that manages care for tens of millions of beneficiaries, $700 million spread across every plan in the country amounts to a rounding error on a per-member basis.
The diagnosis-source restrictions deserve particular attention. CMS has been tightening which clinical encounters can generate the diagnostic codes that drive risk-adjusted payments. Insurers operating in rural counties, where provider networks are thinner and coding infrastructure is less developed, face a disproportionate hit. Fewer qualifying diagnoses mean lower risk scores, which translate directly into smaller capitation checks. Brokers who sell Medicare Advantage plans have warned that carriers already operating on thin margins in low-population counties will exit those markets first, leaving rural seniors with fewer private plan options or none at all.
CMS payment components and the gap between proposal and final rule
CMS framed the proposed payment policies as steps toward payment accuracy and sustainability. The agency’s own component tables showed that the effective growth rate, taken alone, would have delivered a larger bump. But risk model revisions and the new limits on diagnosis sources offset most of that growth, dragging the net figure down to 0.09%.
The final Rate Announcement told a different story. CMS ultimately finalized an overall expected average change of 2.48% for calendar year 2027, a significant upward revision from the initial proposal. That jump from 0.09% to 2.48% reflected adjustments CMS made after reviewing public comments submitted through the formal rulemaking docket. The gap between proposal and final rate shows how much pressure the comment period generated from insurers, provider groups, and congressional offices representing districts where plan exits would hit hardest.
Even at 2.48%, the final rate falls below what many large insurers said they needed to maintain current benefit levels. The distance between what carriers requested and what CMS delivered will shape which counties lose plans and which keep them for the 2027 coverage year.
