Some people have Medicare and Medicaid at the same time. Medicare is the federal health program. Medicaid is a joint program. The federal government and the state run it together. It helps people with low income and low savings.
A Dual Eligible Special Needs Plan is built for this group. People call it a D-SNP for short. It is a type of Medicare Advantage plan. It puts Medicare care and Medicaid help on one plan card. It puts them under one set of rules too.
This guide tells who can join. It tells how the two programs meet in one plan. It tells when you can sign up. It tells what steps to take first.

What a D-SNP is
A Special Needs Plan is a Medicare Advantage plan. It has a narrow focus. It serves one group of people. A D-SNP serves people who are dual eligible. That term means a person qualifies for both programs. The person qualifies for Medicare. The person qualifies for Medicaid too.
Most Medicare Advantage plans are open to all. You just need Part A and Part B. A D-SNP is not open to all. It can take only people who pass its Medicaid test too.
Our Medicare Advantage page shows how these plans fit in the wider group. Each firm that sells a D-SNP must follow Medicare rules. Each firm must also work with the state Medicaid agency. Take a large firm such as UnitedHealthcare. Its plan page shows how one firm lists its plans by state.
A D-SNP still gives you the care Medicare covers. The plan may add extra help for members. That help can change by plan. That help can change by state too. Read the plan proof of coverage for the full list. Do not count on a perk you have not seen in print.
Who qualifies
Three tests decide if you can join a D-SNP. You must pass all three.
First, you must have Medicare Part A and Part B. Part A covers care in a hospital. Part B covers doctor visits. Part B covers other care outside a hospital too. You need both parts. Without both parts, you cannot join this type of plan.
Second, you must have Medicaid. This test trips up most people. Medicaid is not one set of rules for the whole country. Each state runs its own program. Each state uses its own groups. Each state uses its own tests for income and savings.
Some people have full Medicaid. Full Medicaid can cover many kinds of care. Other people have partial Medicaid help. For them, Medicaid may help pay Medicare costs. It may not cover full care. A plan may take one group. It may not take the next group. The plan and the state set that match.
Third, you must live in the plan service area. A D-SNP is sold for a set area. That area is often a set of counties. It can be a whole state. Move out of that area, and you may have to leave the plan.
In short, Medicare status gets you to the door. Medicaid status decides if the door opens. Where you live decides your plan choices.
How Medicaid tests work
Medicaid looks at income. Medicaid looks at resources too. Resources are things like cash and bank funds. A home you live in gets different treatment. A car gets different treatment too. Your state can tell you how it counts each item.
Two federal standards show how strict these tests can be. They deal with long term care. They show the form of the tests. They are not a D-SNP cutoff for your state.
Do not use these two sums to judge your own case. Your state may use a different test. The test is for the Medicaid group a D-SNP needs. Your state may count income in a different way. It may count resources in a different way too. Ask your state Medicaid office for help. Ask staff to check your group name. Ask staff to check your status in writing.
Keep proof of your Medicaid status close at hand. A plan will check it when you apply. The state checks it again over time. If your status drops, the plan may have to move you out. You would leave the D-SNP. The plan should give you notice. The plan should give you time to fix the gap. That holds if the state says you still qualify.
- Some states use an income cap for long term care. In those states, the federal standard cap is $2,982 per month. It is a federal standard. State rules vary.
- The federal resource standard for a person is $2,000. It is a federal standard. State rules vary.
How the two programs meet in one plan
Medicare and Medicaid do not merge. Each program keeps its own rules. A D-SNP sits in the middle. It helps the two work side by side.
Medicare is first for most medical care. The D-SNP gives that care through its network. The network has doctors and hospitals. You see doctors in the network. Some care needs a referral. Some care needs prior approval. You follow the plan rules where the plan asks for them.
Medicaid help sits behind Medicare. Your Medicaid group sets the help you get. Medicaid may help with costs Medicare leaves behind. It may cover some care Medicare does not cover too. What it covers turns on your state. It turns on your group too.
The plan must help join up your care. Many D-SNPs give each member a care coordinator. This person helps book visits. This person helps sort out bills too. Some bills cross both programs. Ask the plan who your contact will be. Ask how to reach that person.
Bills can still get crossed. A doctor may bill Medicare. But Medicaid should get a part of that bill. Or a bill may go to the wrong plan. Keep each bill. Call the plan first if a bill looks wrong. Ask the plan to sort out which program should pay.
Who pays for what
Care under a D-SNP can draw on more than one source. The split below is the broad shape. Your plan proof of coverage sets the exact split for you. Your state rules set it too.
Not sure who should pay a bill? Do not pay it at once. Ask the plan first. Ask your state Medicaid office too. Write down the name of each person you speak with. Write down the date of the call.
- Medicare pays through your D-SNP. It pays for covered doctor care. It pays for hospital care. It pays for other care Medicare covers. Plan rules apply.
- Medicaid may help with costs Medicare leaves behind. It may cover some care Medicare does not cover. Your state sets this help. Your Medicaid group sets it too.
- Private pay means you pay a cost from your own funds. This can happen if Medicare does not cover a service. It can happen if Medicaid does not cover it. It can happen if you use care outside plan rules.
When you can enroll
The main window each fall is Medicare Open Enrollment. It runs from Oct 15 to Dec 7. Join a plan in this window, and your change takes effect Jan 1, 2027. Switch plans in this window, and the same date holds.
Use this window to check your D-SNP each year. Plans can change their networks. Plans can change which Medicaid groups they take. Your own Medicaid status can change too. A check each fall helps you avoid a shock in the new year.
Some life changes can open a window at other times. A move is one case. A gain of Medicaid can be a case. A loss of Medicaid can be a case too. The rules for these windows are strict. They turn on your facts. They turn on dates. Ask Medicare to confirm a window before you count on it. Ask your state program too.
Want help with Medicare costs? Read our guide to checking Medicare Savings Programs and Extra Help. Those programs are not the same as a D-SNP. Some people get help from a savings program. Some people get help from Medicaid too. Your state office can check all of them in one visit.
How enrollment works, step by step
Joining takes a few clear steps. Take them in this order. That cuts down on errors.
First, confirm your Medicaid group. Call your state Medicaid office. Ask for the exact name of your group. Ask if that group counts as dual eligible. Ask if it counts for a D-SNP in your state.
Next, confirm your Medicare status. Check that you have Part A. Check that you have Part B. Check the dates they are in effect.
Next, check the plan. Check that your doctors are in the plan network. Check that your hospital is in it too. Check that your drugs are on the plan drug list. Check that the plan service area covers your home address.
Next, apply in the window that fits you. You can apply through the plan. You can apply through Medicare too. Keep proof that your form was sent. Keep the date you sent it.
Last, watch for mail from the plan. Watch for mail from the state too. The plan will send a member card. The plan will send a proof of coverage. The state may ask you to renew Medicaid. Do not miss that renewal date. A lapse in Medicaid can end your place in the plan.
Sample situation
Maria Lopez has Medicare and full Medicaid in her state. She sees two doctors for her heart and her blood sugar. Each doctor sent bills to a distinct place. She often got mail she did not grasp. A friend told her to look at a D-SNP in her county.
Maria called her state Medicaid office first. Staff told her the name of her Medicaid group. They said it counts for a D-SNP. She then checked that both of her doctors were in the plan network. She checked her drugs on the plan list as well.
She applied in the fall window. Her new plan start date was the first day of the new year. The plan gave her a care coordinator. That person helped her book visits and sort out a crossed bill. Maria still had to renew her Medicaid on time. She set a date note on her fridge so she would not miss it. She kept each letter in one folder by her phone. When a bill looked wrong, she called the plan first. She wrote down the name of the person who helped her and what that person said.
Steps to take next
- Call your state Medicaid office. Ask for your exact Medicaid group name.
- Ask if that group lets you join a D-SNP in your state.
- Check that you have Medicare Part A. Check that you have Part B too.
- List your doctors, your hospital, and your drugs.
- Check each plan for your doctors. Check it for your hospital. Check it for your drugs.
- Note the fall window, Oct 15 to Dec 7, and review your choice each year.
- Apply through the plan or through Medicare. Keep proof of the date.
- Watch for renewal mail from the state. Reply on time.
- Get free help if you need it. Your State Health Insurance Assistance Program gives free Medicare advice in each state. People call it SHIP for short.
