Medigap Plans Available in New Mexico
Standardized plans: A, B, C, D, F, G, K, L, M, N

The only difference is the premium and the customer service experience. This standardization makes comparison shopping straightforward.
Plan F: Still available in New Mexico for beneficiaries who became eligible for Medicare before January 1, 2020. Plan F covers all gaps including the Part B deductible. New enrollees after 2020 cannot purchase Plan F.
High-Deductible Plan G: Available in New Mexico. You pay a higher annual deductible before benefits kick in, but monthly premiums are significantly lower than standard Plan G.
New Mexico Medigap Rates: Plan G & Plan N
| Plan | Age 65 | Age 70 | Age 75 |
|---|---|---|---|
| Plan G | $150/mo | Varies | Varies |
| Plan N | $110/mo | Varies | Varies |
These are approximate averages. Your actual premium depends on your carrier, zip code, age, gender, and tobacco use. Always compare quotes from at least three carriers before choosing.
How New Mexico Medigap Pricing Works
New Mexico uses community-rated Medigap pricing, the most consumer-friendly method. Everyone pays the same premium regardless of age. Your rate will not increase simply because you get older, though carriers may still raise premiums due to inflation or rising healthcare costs.
Household discount: Many Medigap carriers in New Mexico offer 5-12% household or spousal discounts when two people in the same household both have Medigap policies.
Plan G vs Plan N in New Mexico
Plan G and Plan N are the two most popular Medigap plans in New Mexico. Here is how they compare:
| Feature | Plan G | Plan N |
|---|---|---|
| Part B Deductible | Not covered (you pay $240/year in 2026) | Not covered |
| Part B Copay | Covered (no copays) | Up to $20 copay for office visits, up to $50 for ER visits not resulting in admission |
| Part B Excess Charges | Covered | Not covered |
| Monthly Premium | Higher | Lower (typically 15-25% less than Plan G) |
| Best For | Predictable costs, no copays | Lower premiums, okay with small copays |
Bottom line: If you want the most comprehensive coverage with no copays at the doctor, choose Plan G. If you prefer lower monthly premiums and do not mind occasional $20 copays, Plan N offers strong coverage at a lower cost.

Common Medigap Mistakes in New Mexico
- Missing your OEP: Your 6-month Medigap Open Enrollment Period is your best window. After it closes, carriers can deny you or charge higher premiums based on health.
- Choosing by carrier name alone: Medigap plans are standardized. A well-known brand’s Plan G costs more but covers the exact same benefits as a smaller carrier’s Plan G.
- Ignoring rate increase history: Some carriers offer low introductory rates then raise premiums aggressively. Ask for 5-year rate increase history before buying.
- Not comparing at least 3 carriers: Premium differences of 30-50% between carriers for the same plan letter are common.
- Confusing Medigap with Medicare Advantage: They are different products. You cannot have both simultaneously (except during limited trial rights).
