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 work for seniors who want more predictable health care costs and access to providers nationwide. They cover gaps in Original Medicare. This helps those with ongoing care needs or limited savings for unexpected bills. Seniors in good health with enough savings may prefer Original Medicare's lower premiums.

When can I enroll in Medigap plans in New Mexico?

The best time to enroll in Medigap is your six-month enrollment window that begins when you turn 65 and enroll in Medicare Part B. During this initial enrollment period, insurers must accept you regardless of health conditions and can't charge higher premiums for pre-existing medical issues.

You can apply for Medigap coverage anytime throughout the year. Outside this window you may face medical underwriting and potential coverage denials.

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

Yes, you can switch from Medicare Advantage to Medigap in New Mexico but the process is harder after age 65. After your initial Medigap Open Enrollment Period at age 65, insurers can check your health and deny coverage or charge higher premiums based on medical conditions.

Your guaranteed coverage rights get limited to specific qualifying circumstances once this initial enrollment window closes.

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.
