Medicare enrollment in New Mexico

There were 452,151 residents enrolled in Medicare in New Mexico as of June 2023, which amounts to about 21% of the state’s population12 (as an aside, nearly 42% of the state’s population is covered by Medicaid,7 so about two-thirds of all New Mexico residents are covered under one of those two public programs).2

For most individuals, Medicare enrollment goes along with turning 65. But younger individuals become eligible for Medicare if they have been receiving disability benefits for 24 months, or if they have end-stage renal disease (ESRD) or amyotrophic lateral sclerosis (ALS). Both in New Mexico and nationwide, about 12% of all Medicare beneficiaries are under the age of 65.81

Frequently asked questions about Medicare in New Mexico

Frequently asked questions about Medicare in New Mexico

What is Original Medicare?

Original Medicare, which includes Medicare Part A (hospital coverage) and Medicare Part B (physician/outpatient coverage), is the same in every state. So overall Medicare eligibility in New Mexico and Medicare enrollment in New Mexico both work the same way they do everywhere else. For people who aren’t yet receiving Social Security benefits and thus aren’t automatically enrolled when they turn 65, the Medicare application in New Mexico is done via the Social Security Administration, as is the case nationwide.

But the availability and pricing of Medicare coverage, including Medicare Advantage plans, Medigap plans, and Medicare Part D prescription drug plans, does vary from state to state.

What is Medicare Advantage?

Medicare Advantage plans are an alternative to Original Medicare. Medicare Advantage plans include all of the healthcare benefits of Original Medicare (albeit with different out-of-pocket costs and typically a much more limited provider network), and many Medicare Advantage plans also include Medicare Part D prescription drug coverage as well as additional benefits like dental and vision coverage.

There are pros and cons to either option, and the right solution is different for each person. Medicare Advantage plan availability varies by county: In Hidalgo County, there are only seven Medicare Advantage plans from which to choose for 2023 coverage, while several other counties have 50 plans available.3

For 2024, the total number of Medicare Advantage plans available in New Mexico is dropping to 62, down from 72 in 2023 (but again, not all plans are available in all areas).6

Nationwide, and in New Mexico, more than a third of all Medicare beneficiaries were enrolled in Medicare Advantage plans as of 2018.91 By June 2023, there were 220,180 New Mexico Medicare Advantage beneficiaries with coverage. That’s nearly 49% of the state’s Medicare population and mirrors the uptick in Medicare Advantage enrollment nationwide. The other 51% of New Mexico’s Medicare beneficiaries had Original Medicare as of 2023.1

The Medicare Annual Election Period (October 15 to December 7 each year) allows Medicare beneficiaries the chance to switch between Medicare Advantage and Original Medicare (and add, drop, or switch to a different Medicare Part D prescription drug plan). There is also a Medicare Advantage enrollment window that allows people who are already enrolled in Medicare Advantage plans to switch to a different Medicare Advantage plan or to Original Medicare. This is the Medicare Advantage Open Enrollment Period, which runs from January 1 to March 31.

What are Medigap plans?

Original Medicare does not limit out-of-pocket costs, so most enrollees maintain some form of supplemental coverage. Nationwide, more than half of Original Medicare beneficiaries get their Medicare Supplemental coverage through an employer-sponsored plan or Medicaid.10 But for those who don’t, Medigap policies (also known as Medicare Supplement insurance plans, or Medigap) will pay some or all of the out-of-pocket costs they would otherwise have to pay if they had only Original Medicare.

According to America’s Health Insurance Plans (AHIP)  analysis, there were 71,459 New Mexico Medicare beneficiaries with Medigap coverage as of 2021.11 The New Mexico Office of the Superintendent of Insurance used to maintain a page that listed the state’s Medigap insurers, but they removed it in 2019 as it was outdated. They confirmed that they do not currently maintain a listing of Medigap insurers in the state, although filing data is available on SERFF. But Medicare’s Medigap plan finder tool shows all of the insurers that offer Medigap plans; there are 31 separate insurers offering Medigap plans in New Mexico as of 2023.4

Although Medigap plans are sold by insurance carriers, the plans are standardized under federal rules, with ten different plan designs (differentiated by letters, A through N). The benefits offered by a particular plan (Plan A, Plan M, etc.) are the same regardless of which insurer sells the plan. However, coverage may vary.12

Unlike other Medicare plan coverage (Medicare Advantage and Medicare Part D prescription drug plans), there is no annual enrollment period window for Medigap plans. Instead, federal rules provide a one-time six-month window when Medigap coverage is guaranteed issue. This window starts when a person is at least 65 and enrolled in Medicare Part B (you must be enrolled in both Medicare Part A and Medicare Part B to buy a Medigap plan).

People who aren’t yet 65 can enroll in Medicare if they’re disabled and have been receiving disability benefits for at least two years; about 12% of New Mexico Medicare beneficiaries are under age 65. Federal rules do not guarantee access to Medigap plans for people who are under 65. Although the majority of the states have taken action to ensure access to Medigap coverage for disabled enrollees, New Mexico is not among them.

The New Mexico Office of the Superintendent of Insurance confirmed that Medigap insurers in the state are not required to offer coverage to applicants under the age of 65. But insurers can do so voluntarily.

New Mexico is also one of several states where pre-Affordable Care Act (ACA) high-risk pools remain operational, with coverage available to supplement Medicare if the enrollee is unable to obtain Medigap coverage.

New Mexico is one of several states where private Medigap insurers are not required to offer plans to people under age 65, but state high-risk pool coverage provides a back-up option. The others are Alaska, Iowa, Nebraska, North Dakota, South Carolina, Washington, and Wyoming.

Disabled Medicare beneficiaries have access to the Medigap Open Enrollment Period when they turn 65. At that point, they can enroll in a Medigap plan with the normal premiums that apply to people who are enrolling in Medicare due to age, rather than disability.

Disabled Medicare beneficiaries have the option to enroll in a Medicare Advantage plan instead of Original Medicare (this includes people with kidney failure, who were not eligible to enroll in most Medicare Advantage plans prior to 2021). Medicare Advantage monthly plan premiums are not higher for those under 65. But Medicare Advantage plans may have more limited provider networks than Original Medicare, and total out-of-pocket costs can be as high as $8,300 in 2023 for in-network care, plus the out-of-pocket cost of prescription drugs.13

Although the Affordable Care Act eliminated pre-existing condition exclusions in most of the private health insurance market, those rules don’t apply to Medigap plans. Medigap insurers can impose a pre-existing condition waiting period of up to six months if you didn’t have at least six months of continuous coverage prior to your enrollment (although not all of them choose to do so). And if you apply for a Medigap plan after your initial enrollment window closes (assuming you aren’t eligible for one of the limited guaranteed-issue rights), the Medigap insurer can consider your medical history in determining whether to accept your application and at what premium.

What is Medicare Part D?

Original Medicare does not provide coverage for outpatient prescription drugs. More than half of Original Medicare beneficiaries nationwide have supplemental coverage via an employer-sponsored plan (from a current or former employer or spouse’s employer) or Medicaid, and these plans often include prescription coverage.10

But Medicare beneficiaries who do not have prescription drug coverage through Medicaid or an employer-sponsored plan may need Medicare Part D in order to have coverage for prescription drugs. Medicare Part D can be purchased as a stand-alone Medicare Part D prescription drug plan or integrated with a Medicare Advantage plan. Medicare Part D prescription drug plan was created under the Medicare Modernization Act of 2003, which was signed into law by President George W. Bush.

Medicare Part D prescription drug plan enrollment is available when a beneficiary first becomes eligible for Medicare. And the Medicare Annual Election Period each fall (October 15 to December 7) allows beneficiaries the opportunity to change to a different Medicare Part D prescription drug plan or enroll for the first time if they didn’t do so when they were first eligible, albeit with a late enrollment penalty if they didn’t have creditable coverage prior to enrolling.

In terms of plan availability, there are 24 stand-alone Medicare Part D prescription drug  plans in New Mexico in 2023, with premiums that start at $8.80 per month.6

A total of 343,672 New Mexico Medicare beneficiaries had Medicare Part D prescription drug coverage as of June 2023. That included 134,505 with stand-alone Medicare Part D prescription drug plans, and 209,167 with Part D prescription drug coverage integrated with Medicare Advantage.1

How does Medicaid provide financial assistance to Medicare beneficiaries in New Mexico?

Many Medicare beneficiaries receive financial assistance through Medicaid with the cost of Medicare premiums and services Medicare doesn’t cover – such as long-term care.

Our guide to financial assistance for Medicare enrollees in New Mexico includes overviews of these programs, including long-term care coverage, Medicare Savings Programs, and eligibility guidelines for assistance.

What additional resources are available for Medicare beneficiaries and their caregivers in New Mexico?

You can contact the New Mexico State Health Insurance Assistance Program with questions related to Medicare eligibility in New Mexico and Medicare enrollment in New Mexico.

The New Mexico Office of the Superintendent of Insurance (Russell Toal) can provide assistance and customer service with a variety of insurance-related issues, and they license and oversee the health insurers, brokers, and agents that offer coverage in the state.

The page details how New Mexico Medicaid can provide assistance to Medicare beneficiaries in the state who have limited financial means.
