About 30,000 Medicare Advantage members in New Mexico will have to find new coverage for 2027 after Presbyterian Health Plan said it is dropping most of its Medicare Advantage offerings. The Albuquerque-based nonprofit, one of the state’s largest insurers and health systems, said the plans were losing money and that walking away would erase roughly $59 million in annual losses. For the affected members, the decision converts a routine fall into a required one: the current plan will not exist next year, and doing nothing is not a viable choice.
What Presbyterian is cutting and what stays
Presbyterian is discontinuing the bulk of its individual Medicare Advantage plans while keeping a narrower slice of its Medicare business. The insurer said it will retain its Dual Eligible Special Needs Plan, which serves roughly 13,000 people who qualify for both Medicare and Medicaid, a population with fewer alternatives and higher needs. The move also comes with about 150 administrative job cuts. The health system framed the retreat as a defensive step to stay financially independent rather than an expansion or a strategic pivot.
The exit is part of a broader wave. Insurers and health systems across the country have been paring back Medicare Advantage for 2027, citing rising medical costs and reimbursement that has not kept pace, a trend that industry coverage has tracked as plan exits escalate. Presbyterian’s decision stands out for its scale within a single state, but the underlying pressure — plans that cost more to run than they bring in — is the same one driving withdrawals nationally.
The money stake for members is concrete. A forced switch can change monthly premiums, deductibles, and the list of covered drugs all at once, and a member who lands on the wrong plan can pay hundreds more over the year or lose access to a preferred pharmacy or specialist. For people on fixed incomes, the difference between a well-matched plan and a hasty pick is not trivial, which is why the fall comparison deserves real attention rather than a quick default renewal into whatever replaces the old plan.

The enrollment window that decides 2027 coverage
The timing lines up with Medicare’s Annual Enrollment Period, which runs from October 15 to December 7. During that window, members whose plans are ending can pick a new Medicare Advantage plan or return to Original Medicare, with coverage starting January 1. Presbyterian members should receive a formal non-renewal notice ahead of the window, and that notice is the trigger to start comparing options rather than a formality to file away.
A plan being discontinued also opens a Special Enrollment Period, giving affected members extra time beyond the standard window to make a change without penalty. That flexibility matters because the choice is not just which Advantage plan to pick, but whether to stay in the Advantage system at all. Returning to Original Medicare means weighing a standalone Part D drug plan and, for many, a supplement to cover the gaps Original Medicare leaves.
Cost is only half of the comparison. A new plan’s monthly premium matters, but so do its provider network, drug formulary, and out-of-pocket maximum, and a plan that looks cheaper can carry a narrower network that excludes a member’s current doctors. Members losing Presbyterian coverage will want to confirm that any replacement includes their physicians and prescriptions before enrolling, since switching again after January is far harder than choosing carefully in the fall.
Why returning to Original Medicare has a catch
The decision to leave Medicare Advantage is easy to make and harder to reverse, because of how supplemental coverage works. When a person leaves an Advantage plan under these circumstances, they may have a guaranteed right to buy certain Medigap policies without medical underwriting, meaning an insurer cannot reject them or charge more for health history. Outside those protected windows, a Medigap insurer in most states can deny coverage or raise the price, which can lock a person into Advantage plans by default.
That is the piece easy to overlook in a rushed switch. A member who moves to a different Medicare Advantage plan this fall keeps things simple but stays inside a network-based system that can change again next year, as Presbyterian’s own exit shows. A member who returns to Original Medicare gains broader provider access but must line up drug coverage and, ideally, a supplement while the guaranteed-issue right is available. The clock on that right is tied to the plan’s termination, not left open indefinitely.
For 30,000 households, the practical task is narrow — read the non-renewal notice, compare plans on total cost and doctor networks, and decide before the window closes — but the larger signal is worth noting. When a major regional insurer walks away from most of its Medicare Advantage book to stop the bleeding, it is evidence that the economics of these plans are tightening, and that the member churn seen in New Mexico this year could repeat elsewhere. The safest assumption for anyone in an Advantage plan is that a stable plan today is not a guaranteed plan tomorrow.
