What is changing in New Mexico

The 2026 Medicare Advantage market in New Mexico includes 68 contract-plan combinations across 33 counties, with 205,699 members in the October 2026 CPSC file. For 2027, 18 of those plans are marked as terminated or non-renewed. The affected population is 60,509 members, or 29.4% of the state’s county-level enrollment.

The largest local impact is in Bernalillo, where 29,674 members (43.2% of the county’s MA enrollment) are in 17 ending plans. The county still has 31 2027 plan options in the crosswalk, so most members should have alternatives in the same county — but the networks and drug lists can differ.

A plan marked continuing is not automatically unchanged. The 2027 crosswalk includes “Renewal Plan,” “Renewal Plan with SAR” (service area reduced), “Renewal Plan with SAE” (service area expanded), and “Consolidated Renewal Plan” (plan ID or plan structure changes). Check the plan detail on each county page, and confirm your doctors and drugs with the plan.
