Medicare Advantage 2027 Payment Changes: What You Need to Know

Every year, the Centers for Medicare & Medicaid Services (CMS) announces how much money it will pay private insurance companies to manage your Medicare Advantage coverage. These payment rates — set through a complex formula that accounts for your age, health conditions, and where you live — are not just an inside-baseball policy detail. They are the financial engine that determines whether your plan can afford to offer $0 premiums, free gym memberships, dental cleanings, or a $150 quarterly over-the-counter allowance. For 2027, CMS has finalized a new round of payment updates that managed care organizations are already scrambling to respond to, and as a Medicare beneficiary, you need to understand what's coming before open enrollment arrives in October 2026.

The payment system CMS uses is called the Medicare Advantage rate notice, and it's released each spring for the following plan year. For 2027, CMS finalized its advance notice and rate announcement earlier in 2026. The headline number that insurers watch most closely is the effective growth rate — the percentage change in base payments compared to the prior year. When that rate rises meaningfully, insurers have more room to expand benefits or hold premiums steady. When it comes in lower than expected, or when CMS simultaneously tightens the risk adjustment model (the formula that pays insurers more for sicker enrollees), plans face pressure to cut somewhere. In recent years, CMS has been recalibrating its risk adjustment methodology to reduce what it determined were inflated payments — a process that has already contributed to benefit reductions and plan exits in some markets between 2024 and 2026.

Risk adjustment is worth understanding because it affects you directly, even if you've never heard the term. Here's how it works: if you have diabetes, heart failure, or chronic obstructive pulmonary disease, CMS is supposed to pay your Medicare Advantage insurer more money to cover your expected higher costs. Insurers have historically been aggressive — sometimes overly so — in coding these diagnoses to maximize their payments. CMS has been auditing and correcting these practices, which means some insurers are now receiving less money per enrollee than they budgeted for. The practical result, which played out visibly in 2025 and 2026, was that several large national insurers — including UnitedHealthcare, Humana, and CVS Health's Aetna — reduced supplemental benefits, raised cost-sharing on certain services, or exited unprofitable counties entirely. The 2027 payment environment continues this recalibration trend.

So what does this mean for your wallet and your coverage? First, if your current Medicare Advantage plan has been offering rich supplemental benefits — think $500 or more in annual dental coverage, vision allowances, hearing aid benefits, or food and utility assistance cards — those extras are the first things insurers cut when federal payments tighten. You may receive your Annual Notice of Change (ANOC) in late September 2026 and discover that your $200 quarterly OTC benefit has been reduced to $100, or that your plan no longer covers out-of-network specialists at the same cost-sharing level. Reading that ANOC document carefully — not setting it aside — is one of the most important financial actions you can take each fall. It arrives before the Annual Enrollment Period opens on October 15, giving you time to compare alternatives.

Second, plan availability itself may shift. Medicare Advantage insurers are not required to offer plans in every county, and when payment rates make a market unprofitable, they leave. In 2026, tens of thousands of beneficiaries in rural counties and certain suburban markets received notices that their plan was being discontinued, forcing them into the Annual Enrollment Period to find new coverage. If you live in a less densely populated area, it's worth checking Medicare Plan Finder at medicare.gov each October to see how many plans are actually available to you — in some rural counties, there may be only two or three options, while urban ZIP codes might have 30 or more. The 2027 payment changes may accelerate consolidation in thinner markets.

Third, premiums may rise even on plans that stay in your market. The average Medicare Advantage premium has remained relatively low in recent years — CMS reported the average monthly premium was around $17 to $18 in 2025 — but that average masks wide variation. Some plans charge $0 in premium while others charge $80 or more per month, and the $0 plans have been under particular pressure as federal payments tighten. If your plan raises its premium for 2027, you'll see that in your ANOC. You can use that as a trigger to shop: a plan with a $35 monthly premium might still be cheaper overall than a $0-premium plan with higher copays for specialist visits or a higher out-of-pocket maximum. In 2025, Medicare Advantage out-of-pocket maximums could reach as high as $8,850 for in-network services, so the premium is only one piece of the cost picture.

For beneficiaries who are frustrated by the instability of Medicare Advantage benefits year over year, the 2027 payment environment may be a moment to reconsider whether Original Medicare paired with a Medigap (Medicare Supplement) policy makes more sense for your situation. Medigap plans — particularly Plan G, which is the most popular option for new enrollees since Plan F was closed to new enrollees in 2020 — offer predictable cost-sharing and work with any doctor or hospital that accepts Medicare nationwide. The trade-off is a higher monthly premium: Plan G premiums typically range from roughly $100 to $200 per month depending on your age, gender, tobacco use, and state of residence, compared to the low or $0 premiums common in Medicare Advantage. However, Medigap plans do not change their benefits annually the way Medicare Advantage plans do, which provides a stability that many beneficiaries find valuable as they age into more complex health needs.

One critical timing issue: if you want to switch from Medicare Advantage to a Medigap plan, you generally need to pass medical underwriting in most states — meaning the insurer can review your health history and potentially charge you more or deny coverage based on pre-existing conditions. There are exceptions. If you're in your first year of Medicare Advantage enrollment, you have a guaranteed right to return to Original Medicare and buy a Medigap plan without underwriting. Additionally, if your Medicare Advantage plan is discontinued or leaves your service area, you qualify for a Special Enrollment Period that includes guaranteed issue rights for certain Medigap plans. Residents of California, Idaho, Illinois, Kentucky, Louisiana, Maine, Maryland, Missouri, Nevada, New Jersey, New York, Oklahoma, and Oregon benefit from a birthday rule that gives them a 30-day window each year around their birthday to switch Medigap plans without medical underwriting — a valuable protection worth knowing about if you live in one of those states.

If you're staying in Medicare Advantage for 2027, the most actionable steps are straightforward. Read your ANOC when it arrives in late September 2026. Use the Medicare Plan Finder tool at medicare.gov to compare all plans available in your ZIP code during the Annual Enrollment Period (October 15 through December 7, 2026). Pay attention to the total cost picture: premium, deductible, copays for primary care and specialists, cost-sharing for hospital stays, and the annual out-of-pocket maximum. Also check whether your specific doctors and preferred hospitals are in-network for any plan you're considering — network changes are common year to year, and a plan that covered your cardiologist in 2026 may not include them in 2027. Free, unbiased help comparing plans is available through your State Health Insurance Assistance Program (SHIP), reachable at shiphelp.org, where trained counselors can walk you through your options at no cost.
