Medicare Supplement

Which Medigap letters can Albuquerque buyers pick today?

If you live in Albuquerque and you're pairing Original Medicare with a Medicare Supplement policy, the first thing to know is that Medigap is standardized by letter. That means a Plan G sold in Bernalillo County covers the same federally defined benefits as a Plan G sold anywhere else in New Mexico — the letter is the benefit set. What can differ is who sells it, how they price it, and which extras (if any) sit outside the standardized chart.

What Medigap actually does

Medigap is a private insurance policy that helps pay some of the costs Original Medicare leaves behind — things like the Part A hospital deductible, coinsurance and copays. It does not replace Medicare. It sits alongside it. Medicare pays first, and your Medigap policy fills in a share of what's left, depending on the letter you chose.

Because the federal government standardizes these plans, comparing letter to letter is straightforward. Every insurer's Plan N includes the same core benefits as every other insurer's Plan N. The differences come down to price, customer service, and how the insurer raises rates over time.

The letters available in New Mexico today

For anyone becoming eligible for Medicare now, New Mexico offers Plans A, B, D, G, high-deductible G, K, L, M and N. Plans C and F are still in force for people who kept them, but they can no longer be sold to anyone who first became eligible on or after January 1, 2020, because they cover the Part B deductible.

Each letter is a different mix of coverage. Some, like Plan G, are more comprehensive. Others, like K and L, have lower premiums but ask you to share more of the cost up front through cost-sharing percentages and an annual out-of-pocket limit. High-deductible Plan G works like a catastrophic version of Plan G: you pay a set deductible before the plan starts filling in gaps.

There is no "best" letter. The right one depends on how you use care, how you feel about paying a predictable premium versus paying at the point of service, and what fits your budget.

How Medigap pairs with Part D

Medigap does not cover prescription drugs. To get drug coverage, most people with Original Medicare and a Medigap policy add a stand-alone Part D plan.

A few Part D facts worth knowing for 2026:

• The Part D out-of-pocket cap is $2,100.
• The Part D maximum deductible is $615.
• The old coverage gap ("donut hole") is gone as of 2025 — Part D now has three phases.
• The Medicare Prescription Payment Plan lets you spread your drug costs across the calendar year in monthly installments instead of paying big amounts at the pharmacy counter.
• IRMAA surcharges begin above $109,000 in income for a single filer in 2026.

You pick your Part D plan separately from your Medigap plan, and you can review your drug plan each fall during the Annual Enrollment Period, October 15 through December 7.

The state rules and windows that shape your choice

The single most important date for Medigap is the start of your six-month Medigap Open Enrollment Period. It begins the month you're 65 or older and enrolled in Part B. During that window, insurers must sell you any Medigap policy they offer at their best available rate for your age group, regardless of your health history. Miss it, and in most situations insurers can use medical underwriting — meaning they can look at your health and either charge more or decline you.

Federal law also gives you guaranteed-issue rights in specific situations, such as losing certain other coverage. Some states add extra protections on top of federal law — things like a "birthday rule" that lets you switch plans without underwriting once a year. Whether any of those apply in New Mexico is a question worth confirming directly with the New Mexico Office of Superintendent of Insurance or with the state's SHIP counselors, who help New Mexicans one-on-one for free.

Pricing method matters too. Insurers can price Medigap using community rating, issue-age rating, or attained-age rating. Two policies with identical benefits can behave very differently over time depending on the method used. Ask any agent or insurer how a specific policy is priced before you sign.

How to find the insurers selling in Albuquerque

Albuquerque is in Bernalillo County, and Medigap availability is set at the state level rather than the county level. To see who's selling which letters in your ZIP code, there are three reliable, no-cost places to look:

• The Medigap policy search at Medicare.gov, which lets you enter your ZIP code and see the letters and insurers available.
• The New Mexico insurance department's Medigap rate guide, which lists licensed insurers.
• The New Mexico SHIP, the state's free counseling program for people with Medicare.
