Roughly 30,000 New Mexico retirees are about to lose the Medicare Advantage coverage they have now, after Presbyterian Health Plan decided to walk away from most of that business for 2027. The Albuquerque-based system pinned the retreat on more than $59 million in losses tied to those plans in 2025, part of a squeeze that has pushed regional insurers out of Medicare Advantage across the country. Current members keep their coverage through the rest of this year, but the plans they count on will not return in January, forcing a scramble for replacements during this fall’s enrollment season. One narrow category of members will be spared, and knowing which side of that line a household falls on is the first thing to sort out.
A $59 million loss drives Presbyterian out of most Medicare Advantage
The decision was framed as a matter of survival for a nonprofit system trying to stay independent. Presbyterian said staying in most of the Medicare Advantage market would drain resources it needs for direct patient care, workforce, and access across New Mexico. Rather than spread thin, it chose to exit the plans losing money and concentrate on the parts of its mission it can still fund.
The financial backdrop was unforgiving. The Medicare Advantage plans being discontinued drove more than $59 million in losses in 2025, and the move comes with roughly 150 health plan and administrative jobs eliminated, though the system said direct patient-care roles are protected. A February credit downgrade from Fitch, citing several years of weak operating performance and rising medical costs, added to the pressure. One product survives the cut: the Medicare Advantage Dual Plus Special Needs Plan, which serves people eligible for both Medicare and Medicaid, will continue in 2027.
The retreat also reshapes what enrollees will be told and when. Federal rules require a Medicare Advantage insurer that will not renew a plan to send affected members a formal non-renewal notice, and those letters are timed to arrive before the fall enrollment season so a household has weeks, not days, to react. The notice states that coverage ends December 31 and points members toward their options, but it does not choose a replacement plan for anyone. Because Presbyterian is keeping only its dual-eligible product, the letters will reach the large majority of its Medicare Advantage enrollees rather than a small slice, which is what turns an insurer’s balance-sheet decision into a statewide shopping event.

About 30,000 New Mexico members must switch for 2027
The disruption is concentrated in a single state. Coverage will not change for the current plan year, so no one loses benefits before January. But the roughly 30,000 members enrolled in the discontinued plans will need to choose new coverage during the Annual Enrollment Period, which runs October 15 through December 7, or risk landing on a default option that may not match their doctors or medications.
The one exception is worth confirming carefully. Members enrolled in the surviving Dual Plus Special Needs Plan, who qualify for both Medicare and Medicaid, keep their Presbyterian coverage into 2027 and do not have to make a change. Everyone else in a standard Presbyterian Medicare Advantage plan is in the group that must shop. Because eligibility for the dual plan hinges on also having Medicaid, members unsure of their status should verify it before assuming they are covered, since the answer determines whether they need to act at all.
The regional-insurer squeeze and what members can do
Presbyterian is not an outlier. Flat federal payment rates for 2027, shifting star-rating rules, and rising medical costs have hit smaller, regional Medicare Advantage carriers hardest, and the same forces have produced exits and shutdowns at plans elsewhere in the country this year. For members caught in the withdrawal, the choice comes down to another Medicare Advantage plan still sold in their county or a return to Original Medicare paired with a drug plan and a Medigap supplement.
The Original Medicare route carries a protection that is easy to overlook. Because the plan is being discontinued, members who switch to Original Medicare gain a guaranteed-issue right to buy a Medigap policy with no health questions, but the application must be filed no more than 63 days after coverage ends. That window is the single most consequential deadline for anyone in poorer health, since letting it lapse means facing medical underwriting that can raise the price or block a policy altogether. There is also a timing protection that softens the scramble: when a Medicare Advantage plan is discontinued, its members qualify for a Special Enrollment Period running from December 8 through the end of the following February, on top of the regular Annual Enrollment Period, so a member who cannot settle on a plan by December 7 is not locked out. That extra window is meant to keep a forced default from becoming permanent, but it does not extend the 63-day Medigap guarantee, which still counts from the date the old coverage ends. A member who intends to return to Original Medicare therefore has to treat the Medigap clock as the binding deadline even while the plan-selection window stays open a few weeks longer. For 30,000 New Mexico households, the enrollment period ahead is less about finding any plan than about choosing the one that preserves both their doctors and their long-term ability to buy supplemental coverage.
