Medicare Supplement Plans in New Mexico: FAQ

Here are answers to common questions about Medigap coverage in New Mexico.

What does Medigap cover in New Mexico?

Medigap in New Mexico fills gaps in Original Medicare by covering Part A and Part B deductibles, coinsurance, copayments, and the first three pints of blood. Select plans also handle Part B excess charges, skilled nursing facility coinsurance, and foreign travel emergencies. However, Medigap excludes prescription drugs, dental, vision, and long-term care services.

Are Medicare Supplement plans worth it?

Medicare Supplement plans cover the gaps that Original Medicare doesn't pay for, which makes them useful for people with ongoing care needs or limited savings.

When can I enroll in Medigap plans in New Mexico?

You can enroll in Medigap at any time of year in New Mexico, but your best window is the six-month open enrollment period that starts when you turn 65 and sign up for Medicare Part B.

Can I switch from Medicare Advantage to Medigap in New Mexico?

Yes, you can switch from Medicare Advantage to Medigap but it's harder after age 65. Insurers may deny coverage or charge higher premiums based on medical conditions.

Our Review Methodology

MoneyGeek collected data for all Medicare plans in New Mexico for 65-year-olds and 75-year-olds, using the plan browsing tool at Medicare.gov. Unless otherwise noted, the data in this article references quotes pulled for 65-year-olds in the state.

We scored Medigap companies in New Mexico based on three main categories to create a weighted score out of 5:

Affordability (50%): Providers with the lowest monthly cost score higher.
Pricing style (20%): Medigap insurers use three methods to determine premiums: Community Pricing, Issue-Age Pricing and Attained Age Pricing. We gave higher scores for pricing styles that are more stable and equitable, as follows: Community Pricing 1.0, Issue-Age Pricing 0.8, Attained-Age Pricing 0.6. Using this scaling, a slightly higher-cost community-rated plan can still score higher overall than a cheaper but more volatile attained-age plan.
Plan availability (30%): Providers with a wider range of plan types score higher, with weighted scoring given to the most popular plan types like Plan G, Plan F and Plan N.
