Medicare Advantage plan exits 2026 are shrinking rural coverage, with UnitedHealthcare and Humana leaving more counties than they enter, impacting patients…by Reginald Hislop, III
Over the past several years the Medicare Advantage story has been one of enrollment growth and plan expansion. The 2026 plan year breaks that pattern, and the direction is not coming from Washington. The two largest MA insurers are contracting their footprints, exit counts are running far ahead of entry counts, and the pullback is being driven by margin pressure inside the plans themselves — not by any federal mandate. That distinction matters, because it is the reverse of what the industry has spent the last two years responding to.
The numbers on the contraction
UnitedHealthcare and Humana, the two largest MA insurers, are exiting more counties than they are entering. Each is now present in roughly 80 percent of U.S. counties, down from nearly 90 percent in 2025. UnitedHealthcare is exiting 225 counties and entering 14. Humana is exiting 198 counties and entering 5.
Aetna, the CVS Health plan, is narrowing its national footprint to 43 states, dropping roughly 90 plans across 34 states and about 100 counties, and exiting one state entirely.
The aggregate effect is a thinner market. Total non-SNP Medicare Advantage and Medicare Advantage-Prescription Drug plan count fell 10 percent, from 3,719 plans in 2025 to 3,373 in 2026, per Oliver Wyman (Medicare Advantage Plans Continue Market Overhauls In 2026). The clearest measure of the human displacement is the terminated-plan count: about 2.6 million MA-PD enrollees, or 13 percent, are in a plan being terminated for 2026, up from 1.3 million the year before, per KFF (Medicare Advantage in 2026: Enrollment Update and Key Trends | KFF).
The zero-plan counties
The sharpest edge of the pullback is geographic. Some 122 counties across 13 states now have no Medicare Advantage plan available at all. The list is heavily rural: Alaska, Montana, the Dakotas, Vermont, Nevada, Idaho, Kansas, Nebraska, Utah, Colorado, California, Minnesota, and Oregon.
For a beneficiary in one of those counties, the choice collapses to Original Medicare or nothing on the MA side (https://rhislop3.com/medicare-advantage-vs-traditional-medicare/). That is a different problem from plan-switching. A beneficiary who loses a plan and has another to choose simply re-enrolls. A beneficiary in a zero-plan county has no MA option to fall back to, which puts the entire post-acute and benefit-network discussion back onto fee-for-service terms.
Why the plans are pulling back
The insurers are citing margin pressure and strategic adjustment, not a regulatory requirement. The phrasing is the tell. This is a market-driven pullback. The plans are consolidating service areas where the risk score, the medical loss ratio, or the reimbursement does not cover the cost of maintaining a rural network.
That is worth contrasting directly with the CMS staffing rule story, which ran in the opposite direction. There, a federal mandate imposed the cost. Here, the plans are choosing to exit because the economics do not work. The result looks similar on the ground — a thinner MA market in rural and lower-density counties — but the cause is entirely different, and operators and beneficiaries should not mistake one for the other.
What it looks like in specific states
Vermont is the most complete example of the exit. UnitedHealthcare is leaving the individual MA market almost entirely, leaving residents mostly with Humana or Original Medicare.
New Hampshire is the scale example. Roughly 77,000 residents are affected. Aetna is exiting most counties — Belknap, Carroll, Cheshire, Grafton, Merrimack, Strafford, and Sullivan — and continuing only in Hillsborough and Rockingham. For a small state, that is a near-total reversal of an insurer’s footprint in a single plan year.
Colorado shows how the state machinery is reacting. The Division of Insurance issued a bulletin requiring insurers to report planned service-area reductions so that SHIP counselors can prepare beneficiaries ahead of open enrollment. Minnesota and Kansas are seeing UnitedHealthcare significantly reduce footprint, concentrated in rural counties.
What this means for providers
The post-acute and skilled nursing side should read this as a network and payer-mix development, not an abstract insurance story. When a plan exits a county, the beneficiaries in that county do not disappear. They re-enroll in another plan, or they land in Original Medicare. Either way, the facility’s payer mix shifts, and the operating consequence is real.
The contract a facility holds with a departing plan in a county the plan is exiting is not worth what it was. The volume the plan represented moves to another payer under different terms, or to fee-for-service. Facilities in the affected counties should be re-underwriting their payer mix for 2026 now, not after the enrollment shift lands.
The broader point is that Medicare Advantage is entering a consolidation phase, and the consolidation is happening at the margin of the market — rural and lower-density counties where the network cost is highest and the revenue is thinnest. The plans are not leaving the MA business. They are leaving the counties where the math does not work. For the facilities that operate in those counties, the payer landscape is changing under them, and the 122 zero-plan counties are the clearest sign that the change is structural, not a one-year adjustment.
