CMS released new 2027 Medicare Advantage and Part D landscape data on Monday, and the first full national look points to less choice for seniors, not more. The total number of Medicare Advantage plans is expected to edge down from 5,553 in 2026 to 5,532 in 2027, even as insurers trim offerings and narrow where those plans are sold.
That matters now because seniors in Medicare Advantage are heading into the next enrollment season with fresh evidence that the plan market is still churning. Nearly 3 million seniors had to find new Medicare Advantage coverage after losing access to old plans in 2026, according to Johns Hopkins research, and the new file shows another round of cutbacks before anyone even sits down to compare options.
Researchers with Stephens found that every major insurer they reviewed reduced the number of individual MA plans offered in 2027. UnitedHealthcare is cutting about 690 plans. Humana is cutting about 2,400. Centene is reducing the number of unique plans by about 3,000, and Elevance is cutting about 150. The picture is not one of a flat market in practice, even if the national total barely changes.
The counties tell the same story. Centene is departing 344 counties for 2027, CVS is exiting 103, UnitedHealthcare is exiting 63 and Elevance is exiting 56. At the same time, Devoted Health is adding 336 counties and Alignment Healthcare is adding 9. For some beneficiaries, that means the plan they have now may not be sold where they live next year. For others, it means the options that remain may look thinner.
Insurers are also increasing cost sharing in the plans that survive, which can leave members paying more even when a plan stays on the shelf. The Trump administration has described the 2027 outlook as one of stability for seniors, but the new data show a market still being pared back at the point where coverage choices are supposed to be widest. The gap between the public message and the plan counts is hard to miss.
The broader pattern is clear: insurers are trying to restore margins after years of unexpectedly high medical spending in the privatized Medicare program, and they are doing it by pulling back on less profitable offerings. Special needs plans are growing again in 2027, even as standalone MA and MA-PD plans are cut, because those products cover members with specific long-term health issues, members who also qualify for Medicaid or members who need institutional care and can deliver higher per-enrollee margins. That leaves seniors in the regular MA market with fewer places to go and, in some cases, more to pay.
What comes next is the enrollment period, when beneficiaries will learn whether their current plan survives, disappears or comes back with a higher cost burden. The unanswered question is not whether the market is changing; it already is. It is how many seniors will be forced to move again, and how many will discover that the plan they kept now costs more to use.
