How to apply for dual Medicare and Medicaid: two applications, two doors
In short: To apply for dual Medicare and Medicaid, you file two applications. Medicare goes through Social Security. Medicaid, or a Medicare Savings Program, goes through your state.
That surprises most families. You'd expect one form that says "both". There isn't one, and nobody at the hospital has time to say so. If the paperwork is what piles up once you know which door is which, a navigator can make those calls and track them. Navigate Care explains how that works and what it may cost on its what you will pay page.
Here is the order that works, and the part nobody explains: which of the two your parent actually needs.
First, work out which kind of "dual" you are after
People with both programmes fall into two groups. NCOA calls them full and partial. Full dual eligibility means full Medicaid benefits on top of Medicare, and it takes a separate Medicaid application. Partial means help with Medicare's own costs through a Medicare Savings Program, or MSP.
The difference matters because the income limits are not the same, and because it decides which form you fill in. Our guide to Medicaid vs Medicare explains why the two programmes exist side by side. This post is about the paperwork.
Step 1: Make sure your parent has Medicare
Medicaid is a second layer. It works best when Medicare is already in place, so start there.
NCOA lists three ways to apply: online at SSA.gov/Medicare, by phone on 1-800-772-1213, or at a local Social Security office. If your mother already gets Social Security benefits, she is enrolled in Parts A and B automatically when she turns 65. Check the mail for the card before you start a form that isn't needed.
If she hasn't enrolled and isn't sure when she should, our step-by-step guide to applying for Medicare covers the enrolment windows. And if the alphabet of parts is the confusing bit, what Medicare Part A and B are sorts it out in one read.
Step 2: Apply to your state for Medicaid or an MSP
This is the application most people never knew existed. Medicare.gov's page on having both says to contact your State Medical Assistance (Medicaid) office. Medicaid.gov is just as direct: "To find out for sure if you're eligible for Medicaid, you must contact your state Medicaid agency."
Why the state? Because each state runs its own programme and sets its own limits. There is no national form and no national number to check your parent against.
NCOA says you can usually apply on your state's Medicaid website, by phone, or in person at a local Medicaid or social services office. If income is a little higher, the better fit may be an MSP. Medicare.gov is blunt about it: "Even if you don't think you qualify, you should still apply." The state decides which programme, if any, fits.
What the three main Medicare Savings Programs pay, and the 2026 monthly income limits
| Programme | What it pays | Income limit, single | Income limit, married |
|---|---|---|---|
| QMB | Part B premium, deductibles, coinsurance and copayments | $1,350 | $1,824 |
| SLMB | Part B premium only | $1,616 | $2,184 |
| QI | Part B premium only; reapply every year | $1,816 | $2,455 |

All three share the same resource limits in 2026: $9,950 for one person and $14,910 for a married couple. Limits are slightly higher in Alaska and Hawaii, and some states approve people above these numbers. So a parent a little over the line is still worth an application. These figures are Medicare.gov's, not ours, and the state makes the decision.
One shortcut exists, and it's worth a phone call. NCOA says that in most states people who get SSI are enrolled in Medicaid automatically, but it advises confirming with your local Medicaid office. It also says an MSP application doubles as a Medicaid application for those benefits, so you don't file twice for the same help. If your parent already gets SSI, ask the office before you start a second form.
What to gather before you apply for Medicaid
You don't need everything on day one. But the state will ask, and the delay is usually a missing document, not a refusal. NCOA says Medicaid may request:
- proof of birth date, such as a birth certificate
- proof of citizenship or lawful residence, such as a passport or green card
- proof of where your parent lives, such as a deed or rent receipts
- proof of income, earned and unearned, such as pay stubs or a Social Security statement
- proof of assets, such as bank statements or life insurance policies
- your parent's Medicare card and any other insurance cards
Assets are the part that trips families up. If your parent needs nursing facility care, the state looks back at what was given away or sold below value. That's a legal and financial question, and we can't answer it. SHIP counselling is free, and your state Medicaid agency or an elder law attorney can. Ask before you move anything. If the real reason you're applying is help at home, how to get a caregiver through Medicare shows where Medicare stops and Medicaid may start.
What happens after you apply
You wait, and you follow up. NCOA says Medicaid decisions typically take up to 45 business days, though many states are faster. Long enough that you shouldn't wait for a letter. Put a date in the calendar and call.
Keep copies of everything you send and write down who you spoke to. If the answer is no, you can appeal. NCOA lists asking for a fair hearing as the first route. We can't say an appeal will succeed, and the deadline to request one is short, so read the notice the day it arrives.
Once your parent has full Medicaid, the two programmes work in a set order. Medicare.gov says Medicare pays first when you're a dual eligible and get Medicare-covered services, and Medicaid pays last. That order is why the Medicare card still matters, even with Medicaid in hand.
Medicare.gov also says people with full Medicaid are automatically enrolled in a Medicare drug plan. If drug costs are the worry, our guide to Extra Help with Medicare shows how that ties in.
Where a navigator comes in
A navigator doesn't fill in your Medicaid application for you, doesn't give legal or financial advice, and doesn't replace SHIP. SHIP counsellors are free, and they're the right first call for eligibility questions.
What a navigator does is the follow-through once your parent is on Medicare: booking the referral, checking the equipment arrived, tracking what happens after a hospital stay. Medicare doesn't automatically cover navigation. It depends on a qualifying condition or need and a provider visit, and we confirm your cost before you start. It is usually $0 with supplemental coverage. If you're not sure whether that's the right kind of help, our compare page lays out the categories.
Here is how Navigate Care can help with this. Your parent is matched with one dedicated navigator, who works by phone and video. Once you've sent the applications, the navigator can help you keep the document list in one place and track the follow-up calls to the state office. They can also coordinate the appointments, referrals and equipment that your parent's coverage is meant to make easier. You still make the decisions, and SHIP is still the place for eligibility questions.
Frequently asked questions
Can you apply for Medicare and Medicaid at the same time?
You can start both in the same week, but they are two applications to two places. Medicare goes through Social Security. Medicaid goes through your state Medicaid agency. Many families do Medicare first, so the card is ready when the state asks for it.
Do I have to apply for Medicaid if I already have Medicare?
Yes, if you want Medicaid. Medicare doesn't enrol anyone in Medicaid. NCOA says full dual eligibility takes a separate Medicaid application. If you only need help with Medicare costs, a Medicare Savings Program application may be the right one instead.
Where do I apply for dual eligibility?
There is no dual office. Apply for Medicare at SSA.gov/Medicare, by phone on 1-800-772-1213, or at a Social Security office. Then contact your State Medical Assistance (Medicaid) office, which Medicare.gov names as the place to apply.
How long does Medicaid take to approve?
NCOA says decisions typically take up to 45 business days, and many states are faster. Your state agency can tell you where your parent's application stands.
What if my parent earns too much for Medicaid?
Apply for a Medicare Savings Program anyway. In 2026 the QI limit is $1,816 a month for one person and $2,455 for a married couple, and some states approve above those limits. Medicare.gov says to apply even if you don't think you qualify.
Who pays first when someone has both?
Medicare. Medicare.gov says Medicare pays first for Medicare-covered services, and Medicaid pays last.
