Headlines about insurers pulling out of counties and plans being terminated have left a lot of Medicare Advantage members wondering if the whole program is on its way out. It is not. Medicare Advantage remains the choice of more than half of everyone on Medicare in 2026, but 2026 is also the roughest year for plan continuity since the program took its current shape, with 2.6 million people forced to pick a new plan.
CoveredUSA breaks down exactly what changed for 2026 in this guide: which states and insurers were hit hardest, why plans are cutting supplemental benefits, and what to do if your Medicare Advantage plan was discontinued. If you are weighing whether to stay on Medicare Advantage or move to Original Medicare, see can I switch from Medicare Advantage to Original and Medigap vs. Medicare Advantage.
Coverage Breakdown
| Market Segment | 2026 Status | What's Happening | What It Means for You |
|---|---|---|---|
| Medicare Advantage nationally | Stable, still growing overall | 34+ million enrolled, 54% of Medicare beneficiaries in 2026; the program continues under federal law with no scheduled end date | The overall Medicare Advantage program is not disappearing |
| County-level plan availability | Shrinking in many rural counties | UnitedHealthcare, Humana, and Aetna each pulled out of dozens to hundreds of counties for 2026 | Check your ANOC letter and medicare.gov before assuming your plan renewed |
| Supplemental benefits (dental, vision, OTC) | Trimmed at many plans | Insurers cut dental and vision/hearing allowances and OTC stipends to offset lower 2026 federal payments | Compare benefits every year during Fall Open Enrollment; do not assume last year's extras carried over |
| Zero-premium Medicare Advantage plans | Still common but less guaranteed | 67% of Medicare Advantage prescription drug plans charge $0 premium beyond the 2026 Part B premium of $202.90 a month | A $0 premium plan may still exist in your county, but compare benefits, not just price |
| Original Medicare | Always available nationwide | Unaffected by insurer exits; available in all 50 states, DC, and U.S. territories via Medicare Part A and Part B | The permanent fallback if your Medicare Advantage plan is discontinued |
Medicare Advantage as a federal program is not ending in 2026; the disruption is concentrated in specific counties, specific insurers, and plan-level supplemental benefits rather than the program as a whole.

Direct Answer: Is Medicare Advantage Going Away in 2026?
No, Medicare Advantage is not going away in 2026. Enrollment still tops 34 million people, 54% of everyone on Medicare, and most insurers are still offering plans. What is changing is where: UnitedHealthcare exited roughly 225 counties and Humana exited roughly 198 counties for 2026, and 2.6 million enrollees, 13% of individual Medicare Advantage members, had a plan terminated, up from 6% in 2024.
What's Actually Happening to Medicare Advantage in 2026
Medicare Advantage is not disappearing as a program, but 2026 is the roughest year for plan continuity in its recent history. UnitedHealthcare and Humana, the two largest Medicare Advantage insurers, each now cover roughly 80% of U.S. counties in 2026, down from close to 90% in 2025, after UnitedHealthcare exited about 225 counties and Humana exited about 198. Aetna, owned by CVS Health, closed nearly 90 Medicare Advantage plans across 34 states and now covers 100 fewer counties for 2026.
Insurers point to two forces squeezing their margins for 2026. CMS finished phasing in the updated CMS-HCC Version 28 risk adjustment model at full weight for payment year 2026, which compresses risk scores and lowers reimbursement compared with the older V24 model. Medical costs also rose faster in many counties than the payments CMS set there. Rather than absorb the loss, insurers narrowed their county footprint to markets where they could still turn a profit, which is why exits are concentrated in smaller, rural counties.
Where Medicare Advantage Options Are Shrinking Most
The 2026 disruption is not spread evenly across the country. Several states had more than 40% of their Medicare Advantage enrollees affected by a 2026 plan exit, and rural counties were hit at roughly twice the rate of urban ones. Vermont was hardest hit of all: 92% of its Medicare Advantage enrollees had their plan exit the market, and 68% of those enrollees have no Medicare Advantage plan left to choose from for 2026. Nationally, only about 28,500 people, roughly 1.1% of everyone affected by a 2026 termination, live in a county with zero Medicare Advantage options, concentrated mostly in rural parts of California, Colorado, Minnesota, Montana, Nebraska, Oregon, South Dakota, and Vermont.
| State | Share of MA Enrollees Affected by 2026 Exits | Zero-Plan-County Risk |
|---|---|---|
| Vermont | 92% of enrollees affected, the highest in the nation | 68% of those enrollees have zero Medicare Advantage options for 2026 |
| Idaho | More than 40% of MA enrollees affected by 2026 plan exits | Rural counties at elevated risk of losing all MA options |
| Wyoming | More than 40% of MA enrollees affected by 2026 plan exits | Rural counties at elevated risk of losing all MA options |
| North Dakota | More than 40% of MA enrollees affected by 2026 plan exits | Rural counties at elevated risk of losing all MA options |
| South Dakota | More than 40% of MA enrollees affected by 2026 plan exits | One of 8 states with zero-Medicare-Advantage-option counties |
Figures reflect the share of each state's Medicare Advantage enrollees whose 2025 plan exited the market for 2026. Most affected enrollees still have at least one alternative Medicare Advantage plan available in their county.

Why Insurers Are Pulling Back: Star Ratings and Bonus Payments
Medicare Advantage plans earn extra federal payments through the Quality Bonus Program based on their CMS Star Ratings, and CMS will spend more than $13 billion on those bonuses in 2026. It got harder to earn a high rating: CMS raised its cut-points for 2026, and substantially fewer contracts reached at least 4 stars, 209 contracts compared with 261 the year before. The nationwide average Star Rating for 2026 was 3.66, barely above 3.65 in 2025. Plans below 4 stars lose bonus revenue, one more reason insurers trimmed benefits or exited counties rather than keep every plan running at a loss.
