What CMS’s 2026 Medicare Advantage Payment Update Means for Seniors

By Brian Bateman | Public Health & Healthcare Policy Reporting

The Centers for Medicare & Medicaid Services (CMS) has finalized its 2026 payment update for Medicare Advantage (MA) plans — the private plans that now cover more than half of people enrolled in Medicare nationwide.

The headline: CMS projects that average payments to Medicare Advantage plans will increase by about 3.7% in 2026, before accounting for plan-specific factors. But that percentage does not automatically determine what you will pay in premiums or what extra benefits your plan will offer.

Instead, the annual rate announcement sets the financial framework for next year’s plans. How insurers respond — through premiums, supplemental benefits, provider networks, or prior authorization policies — will become clearer later this year when plans release their 2026 benefit details.

What CMS Announced for 2026

Each spring, CMS publishes a detailed “Rate Announcement” and technical documents explaining how it will calculate payments to Medicare Advantage plans for the upcoming year.

For 2026, CMS projects an average payment increase of roughly 3.7%. That figure reflects several components combined:

Updates to county-level benchmark payment rates.
Expected changes in enrollee risk scores (which estimate health needs).
Ongoing adjustments related to coding intensity.
Quality bonus payments tied to Star Ratings.

CMS says the update is designed to balance program sustainability, payment accuracy, and beneficiary protections. The agency has emphasized improving oversight and ensuring payments more closely reflect patients’ actual health status.

Risk Adjustment and Coding Changes — Explained Simply

A major driver of Medicare Advantage payments is something called risk adjustment.

In plain terms: plans are paid more for people who are sicker and expected to need more care. CMS uses a statistical model — known as the Hierarchical Condition Category (HCC) model — to estimate each enrollee’s expected costs based on diagnoses and demographic factors.

In recent years, CMS has been updating and phasing in revisions to this model to better align payments with current clinical evidence and to reduce incentives for aggressive coding. The 2026 rate notice continues that transition and maintains a coding intensity adjustment, which is meant to account for differences in how thoroughly diagnoses are documented in Medicare Advantage compared with traditional Medicare.

Why this matters: even small technical changes in risk adjustment can shift billions of dollars across plans nationally. Plans with enrollees who score higher under the updated model may see larger revenue increases than others.

Quality Bonuses and Star Ratings

Medicare Advantage plans also receive quality bonus payments based on their Star Ratings, which measure performance on clinical care, customer service, and patient experience.

Plans with four or more stars can qualify for bonus payments and higher benchmark levels. CMS has continued to refine how Star Ratings are calculated, including methodological updates and guardrails following pandemic-era measurement changes.

For beneficiaries, this means a plan’s quality score can influence how much revenue it receives — which may affect benefit design, though not in a one-to-one way.

How Could This Affect Premiums and Benefits?

Here’s the key point: a 3.7% average payment increase does not automatically mean lower premiums or richer benefits. And it does not mean across-the-board cuts, either.

What may be affected:

Monthly premiums: Some plans may keep $0 premiums, while others could adjust premiums depending on local market conditions and enrollment trends.
Supplemental benefits: Many MA plans offer extras like dental, vision, hearing, or fitness benefits. Payment changes can influence how generous these offerings are, but insurers also weigh competition and enrollment goals.
Provider networks: Plans may modify which doctors and hospitals are in-network.
Prior authorization policies: Utilization management tools can shift as plans respond to cost pressures and oversight requirements.
Out-of-pocket limits: Maximum out-of-pocket caps may change within CMS rules.

In short, payment updates shape the environment, but plan-level decisions determine what enrollees actually experience.

Why This Matters Nationally

More than half of Medicare beneficiaries are now enrolled in Medicare Advantage plans, according to federal data. That means even modest percentage changes in federal payments can have broad financial and policy impact.

The Medicare Payment Advisory Commission (MedPAC), which advises Congress, has repeatedly examined how Medicare Advantage spending compares with traditional Medicare. Policymakers continue to debate how to ensure payments are accurate while maintaining plan participation and beneficiary choice.

Independent analysts at KFF note that while average payment changes make headlines, the real-world effects vary widely by county, insurer, and enrollee mix. Some insurers may see higher revenue growth than others depending on their risk profile and Star Ratings.

What’s Still Uncertain

Right now — in March 2026 — we know the payment framework. We do not yet know the final 2026 premiums, copayments, or benefit details for individual plans.

Those details typically become available before the Medicare Open Enrollment Period, which runs from October 15 to December 7 each year.

Until then, it’s not possible to say definitively whether your specific plan will increase premiums, scale back dental coverage, expand benefits, or leave everything largely unchanged.

What Beneficiaries Should Do Before Open Enrollment

When 2026 plan details are released later this year:

Read your Annual Notice of Change (ANOC) carefully.
Check whether your doctors and hospitals remain in-network.
Review changes to prescription drug formularies.
Compare total out-of-pocket costs — not just premiums.
Consider how supplemental benefits like dental or hearing coverage affect your overall healthcare needs.

The Bottom Line

CMS’s 2026 Medicare Advantage payment update sets the financial guardrails for next year’s plans. The projected 3.7% average payment increase reflects technical adjustments to benchmarks, risk adjustment, and quality bonuses — not a guarantee of better or worse benefits.

For the more than half of Medicare beneficiaries enrolled in Medicare Advantage, the real impact will depend on how individual insurers design their 2026 plans.

The most important step is practical: when plan details are released, review them carefully and compare options. Payment announcements shape the system — but your coverage decisions happen during open enrollment.
