- As in most states, 10 different Medigap plans are offered in New Mexico for 2026.
In New Mexico, as in other states, Medicare includes several types of coverage:
- Original Medicare: This plan is managed by the federal government and includes Part A (hospital insurance) and Part B (medical insurance). It doesn’t include prescription drug coverage.
- Medicare Advantage (Part C): These plans are offered by private insurers and include all Original Medicare benefits along with other perks such as vision, dental, and drug coverage. Some plans have limited provider networks, so beneficiaries should confirm their doctors are in-network before enrolling.
- Medicare Part D: This is a private, stand-alone plan for prescription drug coverage. People can pair Part D with Original Medicare or with a Part C plan that doesn’t include drug benefits.
- Medigap (Medicare supplement insurance): These are private plans that help pay for out-of-pocket costs of Original Medicare, such as copays and coinsurance. Medigap can’t be used with Medicare Advantage. A person can choose among 10 standardized plans.
Availability for private plans varies by county, and beneficiaries can check Medicare.gov for local options.
New Mexico residents can qualify for Medicare at age 65 if they’re U.S. citizens or legal residents for at least 5 years. People under 65 years may also qualify through disability or by living with end stage renal disease (ESRD) or amyotrophic lateral sclerosis (ALS).
When choosing a plan, a person may consider provider networks, costs, and quality ratings. A person has the option to join a plan or modify their coverage during one of the following enrollment periods:
- Initial enrollment: Enroll 3 months before to 3 months after the month of their 65th birthday.
- Open enrollment: Join or change plans from October 15 to December 7.
- Medicare Advantage open enrollment: Switch Medicare Advantage plans or return to Original Medicare from January 1 to March 31.
- Special enrollment period: Enroll after a qualifying life change, such as losing job-based coverage.
A person eligible for Medicare due to a disability will be automatically enrolled. If they are eligible based on age, they will need to enroll.
If a person delays enrolling in Medicare Part B or Part D and doesn’t have other coverage, they may have to pay a late enrollment penalty. This can add to their monthly premium for as long as they have Medicare.
There are various factors people may wish to consider when choosing Medicare in New Mexico:
- Services covered: All Medicare plans must provide the same coverage as Part A and Part B. However, people may want to consider additional benefits that may be important to them, such as gym memberships, vision, and dental.
- Doctor choice: Many Medicare plans have a network of doctors and other healthcare professionals. Before choosing a plan, a person may wish to check that their current doctor is in the plan’s network.
- Out-of-pocket costs: Monthly premiums are not the only costs to consider when choosing Medicare plans. People are also responsible for copayments, coinsurance, and deductibles.
- Healthcare needs: If a person has certain health conditions, such as diabetes or HIV, they may wish to look into Special Needs Plans, which are specially tailored to individual needs.
The New Mexico Aging Services offers a couple of ways people can get help with Medicare:
