More than 3 million seniors were displaced from Medicare Advantage plans going into 2026. The wave is not over. UnitedHealth is shutting plans covering another 390,000 members for 2027, and Humana has announced exits affecting roughly 600,000 more. The reason is the same one executives keep repeating in earnings calls: federal reimbursement rates have not kept pace with actual medical costs, and the math on certain markets no longer works. This page covers exactly what changed, who is affected, which benefits are being cut even for members who keep their plans, and the time-sensitive steps you need to take to protect your coverage.
Key Answers — What You Actually Need to Know
These are the questions we see most often from seniors and their families trying to make sense of the coverage disruption. We pulled every answer from verified insurer filings, CMS data, peer-reviewed research, and direct reporting from earnings calls. No guesswork.
No. You will not fall off a coverage cliff. Federal law requires that if your Medicare Advantage plan exits your county, you are automatically moved back to Original Medicare (Parts A and B) if you take no action. You keep your Medicare coverage — what you lose is the private plan’s extras: the fixed copays, the out-of-pocket cap, the dental and vision bundling, and potentially your prescription drug coverage if it was a MAPD plan. The gap between Original Medicare and what you had with the Advantage plan is real and significant for most seniors, which is why acting during your Special Enrollment Period matters so much.
When your Medicare Advantage plan is terminated or exits your service area, federal rules trigger a Special Enrollment Period (SEP). The window typically starts two months before your plan ends and runs until one month after. During this period you can pick a new Medicare Advantage plan, switch to Original Medicare, or — and this is the part most people miss — enroll in a Medigap (Medicare Supplement) policy with guaranteed-issue rights. Guaranteed issue means the Medigap carrier cannot reject you or charge you more because of pre-existing conditions. That protection lasts 63 days from the date your Advantage plan terminates. Miss that window and insurers in most states can underwrite you, which often means higher premiums or outright denial if you have serious health conditions.
A February 2026 study published in JAMA estimated that roughly 2.9 million Medicare Advantage enrollees faced forced disenrollment entering 2026. The Kaiser Family Foundation put the figure at approximately 2.6 million. Both represent the largest single-year wave of plan exits in the modern Medicare Advantage era. For context: a decade ago, plan exits disrupted tens of thousands of seniors. This is an order-of-magnitude larger. And the exits are continuing — UnitedHealth alone confirmed in October 2026 that plans covering 390,000 additional members will end for 2027, and Humana announced another 600,000 displaced for 2027. The industry term for this is “retrenchment.” For seniors on the receiving end, it is a coverage disruption that requires active response.
Keeping your plan does not mean your benefits stay the same. Across the industry, insurers are reducing what are called supplemental benefits — the extras that made Medicare Advantage attractive compared to Original Medicare. In our review of member communications and industry reporting, the most commonly cut benefits include over-the-counter allowances (monthly credits for health products), meal delivery programs, transportation assistance, fitness memberships (like SilverSneakers), and expanded dental coverage beyond basic cleanings. These are not legally required — insurers can reduce or eliminate them each plan year. CMS sets minimum core benefit requirements, but supplemental perks are discretionary. The 2027 plan year is expected to see more cuts than 2026. Review your Annual Notice of Change (ANOC) letter carefully when it arrives — every word in that document can represent a change to what you had last year.
Size doesn’t insulate a carrier from payment math. UnitedHealth’s CEO Tim Noel said in earnings calls that the company underestimated what its Medicare Advantage plans would cost and failed to adjust benefits and pricing to offset rising medical utilization. The company expects a 20% reduction in government funding between 2023 and 2026 — a figure that makes previously profitable rural and lower-density markets unworkable. The Centers for Medicare & Medicaid Services (CMS) has been reducing payment rates to Medicare Advantage insurers since 2024 as part of a broader effort to reduce federal spending. What those cuts translate to at the individual plan level: fewer dollars to cover members, so carriers either cut benefits, raise premiums, or exit markets entirely. UnitedHealth is doing all three.
For the 2026 plan year, UnitedHealth withdrew from 109 counties across 16 states, affecting predominantly PPO (Preferred Provider Organization) plans. Most cuts were in rural counties. Affected members received non-renewal notices mailed October 2, 2025. For 2027, UnitedHealth has shared a preliminary list covering 34 counties across 12 states with third-party marketing organizations, with full plan-level data publishing October 1, 2026. The only definitive way to check your specific plan and county is through Medicare.gov’s Plan Finder tool, which updates with confirmed plan availability for the following year each October. If you received a non-renewal letter by mail, that is your official notification — keep it, because you may need it to prove you qualify for your SEP or guaranteed-issue Medigap rights.
Yes, significantly. Rural counties are the primary target of plan exits because the economics are hardest to sustain there: thinner provider networks, smaller enrollment to spread fixed costs, fewer in-network specialists, and higher per-member care costs. According to reporting by Insurance Business Magazine, rural beneficiaries faced plan disruptions at roughly double the rate of urban enrollees in the current exit wave. The state of Vermont saw a near-total collapse of its Medicare Advantage market heading into 2026 — by February 2026, only about 21,000 Vermonters, roughly 12% of eligible adults, remained enrolled in a Medicare Advantage plan. Vermont is an extreme case, but the rural pressure is present across dozens of states. If you live in a non-metropolitan county, checking your plan’s renewal status each September is now an annual necessity, not an optional chore.
Original Medicare (Parts A and B) covers hospital and medical care with no out-of-pocket cap — meaning a serious illness could leave you with 20% of costs indefinitely. Medicare Advantage plans have annual out-of-pocket maximums (up to $9,350 in-network for 2026). That cap is one of the most important financial protections in an MA plan. Moving to Original Medicare removes it. On the other hand, Original Medicare has no network restrictions — any doctor or hospital that accepts Medicare takes your coverage, nationwide. Many seniors who were displaced find that pairing Original Medicare with a Medigap Plan G (the most popular supplement option as of 2026) and a standalone Part D prescription drug plan gives them predictable costs and the broadest provider access. The monthly cost of Medigap Plan G varies significantly by age and state — use your guaranteed-issue SEP window if you have one, because it locks in coverage without medical underwriting.
Who Is Cutting What — Insurer by Insurer
Every major Medicare Advantage carrier is pulling back in some form. Here is what each announced, the scale of impact, and what it means in practice for members on those plans.
- Exited 109 counties across 16 states for 2026
- Primarily PPO plans cut; members pushed to HMO or Original Medicare
- Most exits in rural counties — harder cost-to-cover math
- 2027: additional 390,000-member shutdown announced October 2026
- Still covers 94% of Medicare-eligible Americans overall
- Shifting strategy toward HMO models — tighter networks, fewer out-of-network options
- 2025: shed ~500,000 members exiting unprofitable plans
- 2026: footprint narrowed to 46 states, 85% of U.S. counties (down from 89%)
- 2027: ~600,000 more affected — mostly 3.5-star-or-lower plans
- Targeting a 3%+ pretax margin by 2028 — exits are part of that math
- Expects to retain ~40% of affected members in other Humana plans
- That means ~360,000 must find coverage elsewhere for 2027
- Cut standalone Part D prescription drug plan counties for 2026
- Signaled further reductions in government-sponsored business
- Expanding dual-eligible (Medicare + Medicaid) plan offerings
- Tightening provider networks in 2027 alongside UnitedHealth
- CVS Health’s insurance business under significant earnings pressure
- Completely exited stand-alone Part D drug plan market for 2026
- Members on Anthem PDPs had to find new drug coverage
- Scaling back MA plan availability for 2026 alongside other carriers
- Rural markets disproportionately affected, consistent with industry pattern
- Signal from Q2 earnings: government program pullbacks continue
The big national carriers are getting the headlines, but the most severe disruptions are happening with smaller regional plans. Providence Health Plan in Washington state is winding down its entire insurance operation, affecting more than 64,000 Medicare Advantage members. Presbyterian Health Plan in New Mexico confirmed a full exit from Medicare Advantage for 2027. Vermont saw near-total MA market collapse entering 2026. These full-market exits leave seniors in those regions with far fewer alternatives and make the decision between a new Advantage plan and Original Medicare + Medigap especially consequential. We found that members in these markets who waited for the situation to resolve on its own were frequently left scrambling in the final weeks before coverage ended.
Why Every Major Insurer Is Pulling Back at the Same Time
The exits are not random. Three converging pressures — federal payment cuts, post-pandemic cost spikes, and inflated prior-year enrollment projections — have made large parts of the Medicare Advantage market financially unsustainable for insurers simultaneously.
The Centers for Medicare & Medicaid Services (CMS) has been reducing reimbursement rates to Medicare Advantage carriers since 2024 as part of federal spending reduction efforts. UnitedHealth projected a 20% drop in government funding between 2023 and 2026. The 2027 payment rule from CMS — which some had hoped would stabilize the market — provided only a roughly 2.5% increase, while actual medical cost trends are running significantly higher. More than 100 health organizations formally urged CMS to raise rates above the near-flat proposal, warning of exactly the plan exits now materializing. Even with a final $13 billion payment adjustment for 2027, analysts cited by Axios in September 2026 said benefit cuts and exits were already locked in from earlier bids.
Post-pandemic healthcare utilization is running above insurer projections across the board. More emergency room visits, higher prescription drug costs, more elective procedures deferred during COVID-19 now being addressed — and an aging Medicare Advantage member population with growing chronic condition burdens. UnitedHealth CEO Tim Noel explicitly acknowledged the company failed to adjust plan designs fast enough when utilization patterns shifted. “Member costs for medical care and prescription drugs” came in higher than what the actuarial models supported, forcing the plan exits that followed. The Medicare Payment Advisory Commission (MedPAC) estimated that Medicare Advantage cost taxpayers $76 billion more than traditional Medicare in 2026 alone — a figure reflecting just how much the payment system had been calibrated in insurers’ favor before recent corrections.
The plans being cut first and fastest are PPO (Preferred Provider Organization) plans, which allow members to see providers outside the plan’s network — at a higher cost to the insurer. In rural markets with thin provider networks, PPO designs are especially expensive because out-of-network usage is harder to control. UnitedHealth’s 2026 exits were explicitly described as primarily affecting PPOs. For 2027, the company said it plans to leave markets where it has a higher share of PPO enrollment and shift toward HMO (Health Maintenance Organization) models, which require referrals and restrict members to a specific provider network. For seniors, the shift means fewer choices, more referral requirements, and potentially more prior authorization obstacles — but lower premiums and out-of-pocket exposure on paper.
How the Contraction Has Unfolded — and Where It’s Going
Even If Your Plan Stays — Here’s What’s Being Cut
The exits are the headline, but the quieter story is what’s happening to the supplemental benefits inside plans that are staying. In our review of Annual Notices of Change from member households and industry-wide analysis, these are the benefits facing the deepest cuts for 2027 plan designs.
Over-the-counter (OTC) health product allowances — monthly or quarterly credits that members could use to buy vitamins, first-aid supplies, and personal care items — became one of the most popular Medicare Advantage selling points in the early 2020s. Some plans were offering $200 or more per quarter. Those allowances are being cut across the board. We found members receiving 2027 ANOC letters showing their quarterly OTC credit cut by 30–60%. For a senior who had built those allowances into their monthly budget, this is a meaningful reduction in plan value — but because it is not a core benefit, CMS does not require any minimum level of OTC coverage.
Most Medicare Advantage plans that “include dental” are now distinguishing between basic coverage (preventive cleanings, X-rays) and comprehensive coverage (fillings, crowns, dentures). The comprehensive dental coverage is what’s being eliminated or capped at much lower dollar amounts for 2027. Newsweek’s reporting in 2026 noted that “most plans continue to offer core benefits like dental, vision, and hearing coverage” — but the word “core” is doing heavy lifting there. A $1,500 annual dental benefit that covered a crown is not the same as a plan that offers two cleanings per year. Read your ANOC’s dental section specifically, and confirm the dollar cap on restorative procedures, not just whether dental is listed.
Non-emergency medical transportation benefits (rides to doctor appointments) and post-hospitalization meal delivery programs are supplemental benefits CMS does not require, and they were among the first to be cut as insurers tightened margins for 2026 and 2027. In our review of member feedback, transportation benefits were especially painful for rural members who had no alternative for reaching specialist appointments. Some plans are maintaining a reduced version — a capped number of rides per year — while eliminating open-ended transportation benefits entirely. If transportation access is a real need in your household, confirm the specific ride limit in your plan before it renews.
Fitness program access — most commonly SilverSneakers — has been reduced or eliminated in a meaningful share of plans being redesigned for 2027. SilverSneakers itself remains available as a standalone product, but the free inclusion through an MA plan is no longer something every member can count on. Check your 2027 plan’s wellness benefits section specifically, and if you rely on gym access through your current plan, verify it remains in the renewal before assuming continuity.
Medicare Advantage vs. Original Medicare + Medigap — The Real Comparison
For seniors being forced off a Medicare Advantage plan, the most important decision is whether to find a new MA plan or switch to Original Medicare with a supplement. Here is how the two approaches compare on the factors that actually matter in practice.
| Factor | Medicare Advantage (MA) | Original Medicare + Medigap G |
|---|---|---|
| Monthly premium | Often $0–$50/month (plan base) | Medigap Plan G: ~$100–$250+/month (varies by age, state) |
| Out-of-pocket cap | Yes — up to $9,350 in-network (2026) | Effectively capped by Medigap — very limited exposure after deductible |
| Provider network | Restricted — must use in-network or pay more (PPO) or get referrals (HMO) | Any doctor or hospital that accepts Medicare — nationwide, no referrals needed |
| Prior authorization | Yes — insurers require approval for many procedures; denials are common | None for services covered by Medicare |
| Drug coverage | Bundled in most MAPD plans | Requires separate Part D plan (~$20–$50/month additional) |
| Dental / vision extras | Often included (though being cut in 2027) | Not included — requires separate dental/vision coverage |
| Medigap eligibility | Cannot have Medigap while on MA — no layering allowed | Medigap supplements Original Medicare — no coverage gap |
| Switching flexibility | Can switch during AEP (Oct 15–Dec 7) or OEP (Jan 1–Mar 31) | Switching back to Original Medicare is easy; getting new Medigap may require underwriting if not in a guaranteed-issue window |
| Best for | Lower monthly cost, bundled extras, willing to use in-network providers | Predictable costs, chronic conditions, frequent specialist use, travel, or rural living with limited networks |
The Center for Medicare Advocacy’s managing policy attorney Kata Kertesz noted in a March 2026 KFF Health News report: “If someone is in a Medicare Advantage plan for several years and then wants to switch to original Medicare, they may find they can’t switch and also get a Medigap plan.” Here is why: in most states, outside of your initial Medicare enrollment period and specific guaranteed-issue windows (including a plan termination), Medigap insurers can medically underwrite you. If you have diabetes, heart disease, cancer history, or most serious chronic conditions, you may be denied or charged significantly higher premiums. The guaranteed-issue window triggered by a plan exit is one of the few times this protection resets. That window is the most valuable thing in your non-renewal letter. Do not let it expire without exploring your Medigap options.
What to Do Right Now — Step by Step
Whether your plan has already been terminated, you received a non-renewal notice, or you are simply reviewing coverage ahead of the next enrollment period, here is the prioritized action sequence based on what we have seen work for members navigating plan exits.
Annual Enrollment Period (AEP) runs October 15 – December 7 each year — this is when anyone can change Medicare Advantage plans for the following year. Medicare Advantage Open Enrollment Period (OEP) runs January 1 – March 31 — current MA enrollees can switch plans or return to Original Medicare. Special Enrollment Period triggered by a plan exit typically begins two months before plan termination and runs until one month after. Medigap guaranteed-issue window: 63 days from plan termination date. Part D late-enrollment penalty: applies if you go more than 63 days without creditable drug coverage after leaving an MAPD plan.
