CMS finalized its Medicare Advantage payment rates for 2027 on April 6, 2026 — a bigger increase than initially proposed, following heavy pushback from the insurance industry. Here’s what changed, why the number moved so much, and what it could mean when you compare plans this fall.

What CMS just decided

The final CY 2027 Rate Announcement sets a net average payment increase of 2.48% to Medicare Advantage plans — over $13 billion in additional payments nationally. Factoring in expected risk score trends, insurers estimate the real impact closer to 4.98%, or roughly $26 billion.

Why the number moved so much between proposal and final

Back in January, CMS’s initial Advance Notice proposed a nearly flat 0.09% increase — a fraction of what plans ultimately received. Between the proposal and the April final announcement, CMS reversed course on a planned update to the risk adjustment model, choosing to keep using the existing 2024 model rather than recalibrating it with newer data. That single decision avoided what would have been a meaningful payment cut, and is largely responsible for the gap between the proposed and final numbers.

What this could mean when you compare plans this fall

More generous federal funding makes it somewhat less likely that plans will need to cut benefits or raise costs sharply to stay profitable for 2027 — insurers had warned they might trim benefits or exit certain markets if rates came in too low. That said, a national funding increase doesn’t guarantee any specific carrier or plan in Carver County passes that funding through as better benefits; it varies by plan. It’s still worth a real comparison during this fall’s Annual Enrollment Period rather than assuming your current plan automatically benefits.

The other change worth knowing: tighter rules on risk coding

CMS also finalized stricter rules on which diagnoses count toward a plan’s risk-adjusted payments — specifically excluding diagnoses from certain chart reviews not tied to an actual patient visit, and from audio-only telehealth visits. This is aimed at reducing overpayment tied to aggressive coding practices industry-wide, separate from the base rate increase itself.

Not necessarily — the rate increase affects how much CMS pays plans, not directly what you pay. How that funding translates into premiums or benefits depends on each individual carrier and plan, which is why comparing options during AEP still matters.
After industry pushback following the January Advance Notice, CMS chose not to finalize a planned update to the risk adjustment model that would have reduced payments. That reversal, along with updated cost data, pushed the final rate well above the initial proposal.
It’s the mechanism CMS uses to pay Medicare Advantage plans more for covering sicker patients and less for healthier ones, based on diagnosis codes. The new rules restrict which diagnoses can count toward that calculation, aimed at reducing inflated risk scores.
Not automatically — this is context for why plans might be more stable heading into 2027, not a reason on its own to switch. Reviewing your specific plan's changes during AEP is still the more useful exercise.
