What Are Medicare Advantage Plan Terminations?
Medicare Advantage plan terminations happen when health insurers stop offering coverage in specific markets or reduce their service areas. As a result, enrolled seniors must find entirely new plans — ones that may not include their existing doctors, hospitals, or drug benefits.
Medicare Advantage plans contract with the federal government to deliver traditional Medicare benefits alongside added services. These extra perks commonly include disease management programs, nurse helplines, vision care, dental services, and wellness programs. Together, these features make Medicare Advantage an attractive option for millions of older Americans.
How Many Seniors Were Affected in 2025?
A Sharp Rise in Plan Exits
New research from KFF exposes the full scale of recent market upheaval. Notably, 2.6 million people enrolled in Medicare Advantage Prescription Drug (MA-PD) plans lost their coverage at the end of 2025. Insurers discontinued these plans or scaled back the geographic areas they served.
Consequently, plan terminations affected 13% of all individual MA-PD enrollees in 2025. This figure is substantially higher than the 6% affected in 2024, marking a dramatic and concerning year-over-year jump. In other words, the disruption more than doubled in a single year.
Who Was Most Impacted?
Seniors enrolled in MA-PD plans — which bundle medical, hospital, and prescription drug coverage into one package — bore the brunt of these exits. Together, these individuals represent more than 1 in 10 Americans enrolled in Medicare Advantage plans with drug coverage.
Why Are Insurers Pulling Back?
Rising Costs Drive Market Retreats
After years of aggressive geographic expansion, several major health insurers began scaling back their Medicare Advantage footprints. UnitedHealth Group’s UnitedHealthcare, CVS Health’s Aetna, Elevance Health, and Humana all reduced their presence in certain markets for 2026.
These companies faced mounting pressure from rising healthcare costs among seniors, who exhibited pent-up demand for medical services in the years following the pandemic. Therefore, insurers started exiting unprofitable markets and refocusing on regions where they maintain strong provider networks.
Fewer Plan Options on the Market
The average Medicare beneficiary now has access to 32 MA-PD plan options in 2026, down from a peak of 36 in 2024. Although this decline is noteworthy, the current number still surpasses plan availability in 2022 and all years prior. Overall, the market remains relatively diverse despite recent contractions.
What Happens to Prescription Drug Coverage?
Drug coverage becomes the central concern for seniors when Medicare Advantage plans exit. Fortunately, KFF reports that virtually all Medicare beneficiaries still have at least one zero-premium plan with prescription drug coverage available in their area.
Additionally, nearly all plans — at least 98% — continue to offer vision, dental, and hearing benefits. These are benefits that traditional Medicare does not cover, making them a key reason why seniors choose Medicare Advantage in the first place. Even amid insurer retreats, access to these benefits has remained largely intact.
Is the Medicare Advantage Market Still Strong?
Despite the wave of insurer exits, KFF concludes that the Medicare Advantage market “remains robust in terms of enrollment, plan choice, and extra benefits.” Total enrollment recently surpassed 35 million older adults, which represents more than half of all eligible Medicare beneficiaries.
Moreover, rebate payments to plans from the federal Medicare program are projected to reach a record high — averaging more than $2,600 per enrollee in 2026. These rebates must fund lower cost-sharing, extra benefits, and premium reductions, offering direct financial value to seniors across the country.
What Comes Next for Seniors?
Federal Reimbursement Rates in the Spotlight
The future of Medicare Advantage largely depends on how the federal government pays insurers. The Trump administration proposed a near-flat reimbursement increase of just 0.09% for Medicare Advantage plans. Health insurance industry groups warn that this low rate will push even more insurers to exit markets or cut drug benefits in the coming years.
A formal decision from the administration is expected next month. Its outcome could significantly influence insurer behavior for 2027 and beyond.
Industry Concerns Grow Louder
Health insurers and plan lobbies argue that insufficient payment rates directly harm seniors’ access to quality care. Without meaningful reimbursement improvements, more insurers may continue their retreat — narrowing the plan choices available to seniors in communities across the United States.
Nevertheless, KFF’s analysis offers cautious reassurance. The market still provides strong competition, broad benefit packages, and record rebate levels. However, sustained vigilance from both policymakers and beneficiaries will be critical to preserving the coverage quality seniors depend on.
