Medicare 101
Medicare vs Medicaid
Medicare and Medicaid sound alike and do different jobs. Medicare is federal health insurance based mainly on age or disability — you earn it through work credits and pay premiums like $202.90 a month for Part B in 2026. Medicaid is a joint federal-state programme based on income and resources, administered in New Mexico by the state. Roughly one in five Medicare beneficiaries has both, and that combination unlocks the most generous coverage available.
Side by side
| Medicare | Medicaid | |
|---|---|---|
| Who runs it | Federal government | Federal + New Mexico jointly |
| Who qualifies | Age 65+, or disability/ESRD/ALS | Income and resources below state limits |
| Based on | Work credits and age | Financial need |
| Cost to you | Premiums, deductibles, coinsurance | Little or nothing |
| Long-term custodial care | Not covered | Covered once eligible |
| Where to apply | Social Security | NM Health Care Authority |
The long-term care difference
This is the most consequential distinction. Medicare does not pay for long-term custodial care — help with bathing, dressing, and daily living — at home or in a facility. It covers only short skilled stays after a qualifying hospital admission.
Medicaid does pay for nursing facility care, once your assets and income fall within state limits. That is why so much retirement planning revolves around Medicaid rules, and why long-term care coverage is worth understanding before you need it.
Having both — dual eligibility
If you qualify for both, Medicare pays first and Medicaid picks up much of what's left — often including your Part B premium, deductibles, and coinsurance. You also automatically qualify for Extra Help with drug costs.
Dual-eligible members can enrol in a D-SNP, a Medicare Advantage plan built specifically for this situation that coordinates both programmes into one plan and one card. Details are on Medicare.gov.
The middle ground: Medicare Savings Programs
Many people have too much income for full Medicaid but still qualify for help. Medicare Savings Programs are Medicaid-administered but far more accessible.
- QMB — pays your Part B premium, deductibles, coinsurance, and copays.
- SLMB — pays your Part B premium.
- QI — pays your Part B premium, funded annually and first-come, first-served.
Any of these pays the $202.90 monthly Part B premium — real money — and automatically qualifies you for Extra Help. See Medicare.gov; apply through the New Mexico Health Care Authority. These programmes are significantly underused in New Mexico.
How to apply in New Mexico
Medicare and Medicaid are separate applications to separate agencies.
- Medicare — Social Security, online or by phone: ssa.gov.
- Medicaid and Medicare Savings Programs — the New Mexico Health Care Authority, online, by phone, by post, or in person.
- Extra Help — Social Security, separately and free.
Have proof of income, account balances, and your Medicare card ready. Free unbiased help is available from your State Health Insurance Assistance Program, and we'll walk you through it at no cost.
Common misunderstandings
- "Medicaid is only for people with no money." Medicare Savings Programs reach well beyond that, and most people who qualify never apply.
- "If I have Medicaid I don't need to choose a Medicare plan." You still choose, and a D-SNP is usually the better fit.
- "Medicare will cover the nursing home." It won't, beyond a short skilled stay.
- "Applying puts my house at risk." Rules on the primary residence and estate recovery are specific — get real advice rather than assuming.

How dual coverage works day to day
Having both changes what happens at the pharmacy counter and the doctor's desk, not just on paper.
- At the doctor — Medicare pays first, Medicaid may cover the remaining coinsurance and deductibles depending on your category.
- At the pharmacy — your Part D plan pays, and Extra Help caps your copay at a few dollars per prescription.
- Balance billing — providers generally may not bill QMB members for Medicare cost sharing. If you receive such a bill, it's usually an error worth challenging.
- Changing plans — dual-eligible members get extra opportunities during the year rather than waiting for autumn.
Estate recovery and your home
The question we're asked most about Medicaid is whether it takes the house. The honest answer is that it's more nuanced than either the fear or the reassurance suggests.
States are required to seek recovery from the estates of people who received long-term care Medicaid, and the primary residence is not automatically exempt from that process after death — though it is generally protected while a spouse or certain dependants live there. Transfers made within five years of applying are also subject to a look-back that can cause a penalty period.
These rules are specific, they change, and they interact with New Mexico law. Before transferring property or spending down assets, get advice from an elder-law attorney — not from a general web page. What we can do is tell you clearly where the Medicare side ends and the Medicaid question begins.
Applying without getting stuck
The application itself defeats a lot of people who would have qualified, so it's worth knowing what to expect.
Gather proof of income for everyone in the household, recent statements for every account, your Medicare card, and proof of identity and residence before you start. Incomplete applications are the most common cause of delay, and a request for missing documents usually comes with a short deadline attached.
If you're denied, you have the right to appeal, and denials on paperwork grounds are frequently reversed once the missing item is supplied. If your circumstances change — income drops, a spouse dies, you enter a care facility — you can reapply; a previous denial does not bar you.
Free help is available from your State Health Insurance Assistance Program and from us, and neither costs anything. Given how many New Mexicans qualify for a Medicare Savings Program without knowing it, applying is usually worth the hour it takes.
Which one pays first, and why it matters
When you have both, the order of payment is fixed: Medicare is the primary payer and Medicaid is the payer of last resort. That sequence has practical consequences worth understanding.
It means your Medicare plan choice still matters — Medicaid isn't a substitute for choosing a good Advantage or Part D plan, it's a backstop behind whatever you choose. It also means providers must bill Medicare first, and a provider who won't accept Medicaid as secondary can leave you exposed to cost sharing you shouldn't be paying.
For people in the QMB category in particular, federal rules generally prohibit providers from billing you for Medicare deductibles and coinsurance at all. Bills of that kind do still get sent, usually in error. Don't simply pay one — bring it to us or to your State Health Insurance Assistance Program, because the fix is usually straightforward once someone points out the rule.
Questions, answered
Can I have both Medicare and Medicaid?
Yes — that's called being dual-eligible. Medicare pays first and Medicaid covers much of the rest, often including your Part B premium and cost sharing. You also get Extra Help with drug costs automatically.
Does Medicare or Medicaid pay for a nursing home?
Medicaid does, for long-term custodial care, once you meet state income and asset limits. Medicare covers only short skilled stays after a qualifying hospital admission.
What if my income is too high for Medicaid?
You may still qualify for a Medicare Savings Program, which pays your $202.90 Part B premium and sometimes more. The income limits are considerably higher than for full Medicaid, and the programmes are underused.
Where do New Mexicans apply for Medicaid?
Through the New Mexico Health Care Authority — online, by phone, by post, or in person. Medicare is a separate application through Social Security.
