In New Mexico, tens of thousands of older residents are about to lose the Medicare Advantage plan they have relied on. Presbyterian Healthcare Services, one of the state’s largest health systems, is ending most of its Medicare Advantage plans for 2027, a decision that affects roughly 30,000 members and comes paired with about 150 layoffs. For the households involved, the coming months are a scramble to find replacement coverage before the current plans go dark.
Why Presbyterian is pulling most of its plans
The reason Presbyterian gives is financial. The Medicare Advantage plans it is discontinuing drove more than $59 million in losses in 2025, a level of red ink the nonprofit system says it cannot keep carrying. As trade outlet Becker’s Payer reported, the exit will also eliminate about 150 health-plan and administrative jobs. Presbyterian is not a national insurer trimming a few underperforming markets; it is a regional system stepping back from a line of business that was losing money on every renewal.

Who is affected, and who is not
Not every Presbyterian member loses coverage. The system is keeping its Medicare Advantage Dual Plus Special Needs Plan, which serves about 13,000 members who are eligible for both Medicare and Medicaid, according to Healthcare Finance News. Those dual-eligible members are among the most financially vulnerable in the program, and their plan stays in place. It is the roughly 30,000 members on the discontinued plans who have to act.
The distinction matters because it tells a member what bucket they are in. A household enrolled in a standard Presbyterian Medicare Advantage plan should assume its coverage is ending unless a notice says otherwise. A household in the Dual Plus Special Needs Plan is, based on the company’s announcement, staying put. When in doubt, the plan name on the member’s card and the notice in the mail settle the question.
The switch clock starts with the Annual Notice of Change
Every Medicare Advantage plan that is ending must tell its members in writing, and that document is the Annual Notice of Change, mailed by late September. For Presbyterian members on a discontinued plan, that letter is the official word that the plan is going away and the trigger to start shopping. It is easy to set aside as routine insurer mail, but this year it carries a deadline. A member who ignores it risks having no plan in place when the calendar turns.
The practical move on receiving that notice is to read what it says about the member’s specific plan, then compare alternatives rather than waiting to be auto-assigned somewhere. When a plan is fully discontinued, there is no default renewal to fall back on; the coverage simply ends, which makes the shopping step non-optional.
Comparing new coverage: cost and network are the pressure points
The replacement search runs through Medicare’s Open Enrollment period, October 15 to December 7, with new coverage effective January 1. Members losing a plan involuntarily may also qualify for a special enrollment period, but the standard window is the reliable path. The federal government’s guide to joining a plan lays out the two basic directions: switch to another Medicare Advantage plan, or return to Original Medicare and add a standalone drug plan.
The two things worth checking hardest are network and cost. Because Presbyterian is a health system as well as an insurer, some members may have been using Presbyterian doctors and hospitals through their plan; moving to a new insurer can change which providers are in network. A member who wants to keep a specific doctor should confirm that doctor participates in whatever plan they are considering. On cost, the comparison should weigh the premium alongside copays, the drug formulary, and out-of-pocket exposure, not the premium alone. A plan that looks cheaper up front can cost more once a household’s actual prescriptions and doctors are plugged in.
Why plan exits are worth a household’s attention this year
Presbyterian’s retreat is part of a broader pattern of insurers and health systems pulling back from Medicare Advantage plans that lose money, and that pattern is landing on ordinary households as forced switches. For an affected member, the stakes are concrete: keep the same doctors or not, pay more or less each month, and get every regular prescription covered or not. None of that is decided by the headline; it is decided in the details of the replacement plan a member chooses before December 7. The households that come through this in good shape will be the ones who open the September notice, compare on total cost and network, and enroll on time rather than letting the clock run out.
