Dual-Eligible Special Needs Plans (D-SNPs) Explained

Who Is “Dual Eligible” in the First Place?

“Dual eligible” means you are enrolled in Medicare and you also receive help from your state’s Medicaid program. People get there in different ways. Some qualify for Medicaid because of very low income and limited assets. Some receive Medicaid because of a disability or a long-term care need. Others are not full Medicaid enrollees but are in a Medicare Savings Program, a state program that pays Medicare premiums and sometimes deductibles and copays. Our post on Medicare Savings Programs covers the individual programs.

The distinction between “full” and “partial” dual eligibility matters here. Full-benefit dual eligibles get Medicaid coverage for services Medicare does not pay for, such as long-term care in many cases, plus help with Medicare costs. Partial-benefit duals generally get only help with Medicare premiums or cost sharing. Whether partial-benefit duals can join a D-SNP depends on the state and on the individual plan, so confirm eligibility before assuming anything.

If you are dual eligible, you are also generally eligible for Extra Help with drug costs, which we cover in our guide to the Part D Low-Income Subsidy. A D-SNP includes Part D drug coverage, and Extra Help works inside it the same way it does in other drug plans.

What a D-SNP Is, and What It Is Not

A D-SNP is a Medicare Advantage plan. That means it is run by a private insurer under contract with Medicare, it covers everything Original Medicare covers, it uses a provider network, and it can add benefits that Original Medicare does not offer. It is not Medicaid, and it is not a Medigap policy. In fact, you cannot use a Medigap policy alongside any Medicare Advantage plan, D-SNPs included.

What makes it “special needs” is that it is limited to people who are dual eligible, and by law it has to meet a minimum standard for coordinating your Medicare and Medicaid benefits. At a minimum, the plan has to have a contract with your state Medicaid agency and share certain information with the state, such as hospital and nursing facility admissions for higher-risk members. Many plans go well past the minimum, and that is where the differences begin.

Three Kinds of D-SNP

Type	Medicare side	Medicaid side
Coordination-only	D-SNP plan	Separate state program or plan; D-SNP shares information with the state
Highly integrated (HIDE)	D-SNP plan	Same company family also covers Medicaid long-term services, behavioral health, or both
Fully integrated (FIDE)	D-SNP plan	Same company holds both contracts and covers Medicaid primary, acute and long-term services, and more

Not every D-SNP delivers the same level of integration. Medicare and the states sort them into three groups, and which ones you can pick depends on where you live.

• Coordination-only plans. These meet the basic requirement. They coordinate with the state but do not deliver your Medicaid benefits. Medicaid services still come through the state’s regular Medicaid program or a separate Medicaid health plan, so you may be dealing with two cards and two sets of rules.
• Highly integrated plans (HIDE). The plan, or a company in the same corporate family, also holds a state Medicaid managed care contract that covers Medicaid long-term services, behavioral health, or both. You get more of your coverage through one organization.
• Fully integrated plans (FIDE). One company holds both the Medicare contract and a state Medicaid managed care contract. Beyond Medicaid primary and acute care, federal rules require it to cover long-term services and supports, and from 2025 also behavioral health, home health, equipment and supplies, and Medicare cost sharing. This is the most coordinated version.

According to KFF’s analysis of 2023 data, most D-SNP members were in coordination-only plans, with highly integrated and fully integrated plans covering the rest. The mix is changing as states and Medicare push toward more integration. From 2025, fully integrated D-SNPs are required to enroll only full-benefit dual eligibles whose Medicaid coverage also comes through the same company, which is part of a push to align the Medicare and Medicaid sides of the same plan.

What This Looks Like in Ohio

Ohio has been changing its program for people with both Medicare and Medicaid, so check current details before you decide anything. According to the Ohio Department of Medicaid, its Next Generation MyCare program began January 1, 2026 in the 29 counties that already had MyCare, including Hamilton, Clermont, Butler and Warren counties, and it rolled out to the remaining counties in stages from April through August 2026. The program is built around fully integrated D-SNPs of the kind described above. Adults 21 and older who have full Medicaid and Medicare Parts A, B and D are generally enrolled, with exceptions such as people in PACE, certain developmental disabilities waivers or intermediate care facilities, or people who have other health insurance that covers both hospital stays and doctor visits.

Under the state’s description, your Medicaid benefits come through one of the program’s plans, and if you want your Medicare and Medicaid through the same company, with one card and one care coordinator, you can align your Medicare coverage with that plan. The state says that can be done at any time through Medicare, with the change starting the first day of the following month. The Ohio Medicaid Consumer Hotline at 800-324-8680 can explain your options. A July 2026 Ohio Department of Medicaid presentation also said the state will not extend its Medicaid contracts to coordination-only D-SNPs for 2027, so the coordination-only options available in Ohio may change for next year. If you are in one now, read any notice from your plan and ask the plan or the Hotline what applies to you. Other states handle all of this differently, and a handful of states have had no D-SNPs at all, so it is worth checking locally.

What D-SNPs Usually Offer

Because members tend to have the greatest need and limited income, D-SNPs commonly carry more built-in extras than other Medicare Advantage plans. KFF’s 2024 data show that nearly all D-SNPs include dental, vision, hearing and fitness benefits, and that most also include an allowance for over-the-counter health items, and meal benefits are common. Many D-SNPs also charge no monthly premium and little or no cost sharing, because Medicaid or a Medicare Savings Program covers it.

A care coordinator is another feature that many members value. A D-SNP is required to assess your health needs and have a plan for coordinating your care. In practice, that can mean a named person who helps you schedule appointments, arrange rides and sort out a long-term care need. How good that service is varies from plan to plan, so it is fair to ask how often the coordinator will actually contact you and how to reach them.

Specifics, such as the size of an over-the-counter allowance, change every year. Read the plan’s Evidence of Coverage rather than a marketing summary.

Your Billing Protections

Medicare has a rule that applies to dual-eligible people in the Qualified Medicare Beneficiary (QMB) program: Medicare providers are generally not allowed to bill you for Medicare cost sharing, meaning deductibles, coinsurance and copays. That protection applies whether you are in Original Medicare or in a Medicare Advantage plan, and the provider cannot ask you to waive it. Even so, mistaken bills do happen, because billing offices sometimes miss your status. If a provider bills you for something you believe the QMB rule covers, do not simply pay it. Call the provider, explain your QMB status, and if that does not work, call 1-800-MEDICARE or your State Health Insurance Assistance Program for help. In Ohio that is OSHIIP.

The Trade-Offs

D-SNPs help many people, but they are not automatically the right answer. The honest trade-offs include:

• Networks. A D-SNP uses a provider network. If your doctor, your hospital or your home care agency is not in it, you may lose access to them. With Original Medicare and Medicaid, you can generally see any provider who accepts both, which for some people is a wider choice. Our guide to checking a plan’s network walks through how to verify this before you enroll.
• Prior authorization. Medicare Advantage plans can require approval before certain services. KFF reported, using 2021 data, that D-SNP-only contracts denied a higher share of prior authorization requests than Medicare Advantage plans overall. That statistic is several years old and describes a group of plans and not any single plan, but it is a reason to ask how the plan handles approvals. See our post on how prior authorization works.
• Limited data on quality. Medicare reports quality ratings at the contract level, which can bundle D-SNPs together with other plans, so it can be hard to see how a particular D-SNP performs.
• Original Medicare plus Medicaid is a real alternative. For many full-benefit dual eligibles, Medicaid already picks up the cost sharing that Original Medicare leaves behind. Combined with a stand-alone drug plan and Extra Help, that arrangement offers broad provider choice without a network. It does not come with the extras or the care coordination that a D-SNP can offer. Neither path is wrong. It depends on how you use care.
• Home and community-based waivers. If you receive services through a Medicaid waiver that allows you to stay at home, ask the state or the plan before enrolling, since some waivers and plan types have restrictions.

Changing Plans and Joining Timelines

People with Medicaid or Extra Help have more flexibility than most Medicare enrollees. Since January 2025, dual-eligible people can use a monthly special enrollment period to move into Original Medicare with a stand-alone drug plan, or to switch between stand-alone drug plans. The monthly option cannot be used to join a Medicare Advantage plan. Full-benefit dual eligibles can also use a separate monthly option to join or switch to an integrated D-SNP that is aligned with their Medicaid plan. A change generally takes effect on the first of the following month.

You also keep the usual windows: the annual enrollment period from October 15 to December 7, and the Medicare Advantage open enrollment period from January 1 to March 31. See our overview of the annual enrollment period for details.

Two additional points. In some states, newly Medicare-eligible Medicaid enrollees can be placed in an affiliated D-SNP automatically, though you keep the right to decline. And if you lose your Medicaid eligibility while enrolled, federal rules allow a plan to keep you enrolled for a limited “deeming” period, from 30 days up to six months, if you are expected to regain eligibility in that time. The length varies by plan. A D-SNP is only open to people who qualify, so if you lose Medicaid for good, you will need to change plans.

Questions to Ask Before You Enroll

Before choosing a D-SNP, it helps to put a few questions to the plan or an independent adviser:

• Is this plan coordination-only, highly integrated or fully integrated?
• Are my doctors, specialists, pharmacy and home care provider in the network?
• Are my medications on the formulary, and what prior authorization rules apply?
• What do the dental, vision, hearing and over-the-counter benefits actually pay, and which vendors do I have to use?
• If I use long-term services, how does this plan work with my state’s Medicaid program?
• Who is my care coordinator, and how do I reach them?

A Step-by-Step Way to Decide

A D-SNP decision goes better when you take it in order instead of starting with the plan that has the most appealing brochure. Here is a sequence that works for most people.

Step 1: Confirm exactly which program you are in. “I have Medicaid” can mean several things. You might have full Medicaid, which covers services Medicare does not. You might be in a Medicare Savings Program, which mainly pays Medicare costs. Look for your state’s approval or renewal letter and note the program name and any category, such as QMB, SLMB or QI. A plan will ask, and your answer decides which D-SNPs you can join.

Step 2: Find out which D-SNPs serve your address. Availability is set by county and ZIP code. You can use the plan search on Medicare.gov, call 1-800-MEDICARE, ask your state Medicaid office, or contact your State Health Insurance Assistance Program for free counseling. In Ohio that program is OSHIIP. Write down every option, including plans from the same insurer that differ in type.

Step 3: Ask each plan what type it is. Ask whether it is coordination-only, highly integrated or fully integrated, and, in plain terms, which Medicaid services it actually handles. “We coordinate with Medicaid” is a very different answer from “we manage your Medicaid benefits too.”

Step 4: Test your providers one by one. A name appearing in an online directory is not enough, because directories can be out of date. Call each important provider’s billing office and ask whether it is in network for the specific plan name and plan type you are considering. Keep a note of the date, who you spoke to, and what they said. Consumer advocates who work with dual-eligible clients recommend documenting these calls, since it can matter if there is a dispute later.

Step 5: Check the drug list and your pharmacy. Look up each medication by name, strength and form. If you receive Extra Help, confirm that the plan’s drug coverage works with it, as it should, and that your pharmacy is in network.

Step 6: Look at the Medicaid side. If you use or may soon need long-term services, ask how they are covered, who authorizes them and how you reach someone with authority to approve changes. If you receive services through a home and community-based waiver, ask the plan and your state before enrolling.

Step 7: Compare with Original Medicare plus Medicaid. Price out the alternative honestly: a stand-alone drug plan with Extra Help, and Medicaid or a Medicare Savings Program picking up cost sharing. Ask yourself what the D-SNP adds that you would actually use.

Step 8: Enroll, then verify. After you enroll, confirm the effective date, watch for your new plan card, and check that your pharmacy and key appointments are still on track. Do not cancel anything on the old coverage until you know the new coverage is active.

How It Plays Out in Different Situations

The right answer shifts with the person. These hypothetical examples show how.

Picture someone with full Medicaid who needs help at home. Their biggest question is not dental benefits. It is whether the plan’s care team can approve home care hours quickly and whether their current aide or agency stays in the picture. A fully or highly integrated plan may simplify this, because one company handles both sides. Even so, they should ask exactly how the plan reaches decisions and what happens if hours are reduced.

Picture someone in a Medicare Savings Program only. They do not have full Medicaid, so there is less Medicaid coverage for a plan to coordinate. A D-SNP may still offer lower cost sharing and extras, depending on the state and plan, but they should check carefully what the plan covers beyond Medicare and whether a standard plan or Original Medicare with a drug plan is simpler.

Picture someone who has Medicare and Medicaid and splits time between two states. D-SNPs are tied to a service area and to a state’s Medicaid agreement, so out-of-area care may be limited to emergencies and urgent needs. This person should read the plan’s rules on care away from home before choosing, and may find Original Medicare easier.

Picture someone who sees three specialists at a major hospital system. Network is the whole question. If the system is in the plan’s network, a D-SNP may work well. If it is not, the extras will not make up for losing those doctors.

Common Costly Mistakes

• Choosing for the allowance, not the care. An over-the-counter or grocery card is pleasant, but it is a small part of the value. Providers, drugs and care coordination usually matter more.
• Assuming every D-SNP in the county is similar. Plans differ in type, in network and in how much Medicaid they handle.
• Not checking before enrolling. Because networks and drug lists vary, a plan that looks perfect on paper can leave a regular provider out.
• Paying a bill that should not have come. If you are in the QMB program, providers are generally not allowed to bill you for Medicare cost sharing. Do not pay first and ask later.
• Missing a Medicaid renewal. A D-SNP is only available while you qualify. If your Medicaid or Medicare Savings Program coverage ends because a renewal form went unanswered, you could lose D-SNP eligibility, too.
• Ignoring mail from the plan or the state. Notices about renewals, plan changes and coverage decisions have deadlines.

Keeping Your Medicaid Eligibility While You Are in a D-SNP

Because a D-SNP depends on your Medicaid or Medicare Savings Program status, protecting that status is part of keeping the plan. Your state runs the renewal process, and it can ask for updated income and household information. Keep your contact details current with the state agency, open every letter from it, and respond by the deadline. If you are not sure whether something you received is a renewal, call the number on the letter or the county office.

If your eligibility does end, ask your plan whether it offers a temporary “deeming” period that lets you keep the plan for a short time while you regain eligibility. As noted above, those periods vary by plan. If eligibility is gone for good, you will need to choose different Medicare coverage, and the monthly and other special enrollment periods you may be entitled to can help. Do not wait until your plan ends to make a call.

If Something Goes Wrong

D-SNPs make more promises about coordination than other plans, so it is worth knowing what to do if the coordination fails.

• A service or drug is denied. Ask for the denial in writing. The notice should explain why and how to appeal, with a deadline. Medicare Advantage plans, including D-SNPs, must have an appeals process, and if waiting could seriously harm your health, you can ask for a faster decision. Medicaid services have their own appeal and hearing rights through your state, so ask which process applies to the service in question.
• You are billed for care you should not owe for. Call the provider, explain your coverage and ask them to correct it. If it continues, contact the plan, 1-800-MEDICARE or your State Health Insurance Assistance Program.
• Your provider says it is not in network after you enrolled. Ask the plan whether it has a transition or exception process for out-of-network providers. If you documented your pre-enrollment call, share it.
• You enrolled and it is not working. As described above, dual-eligible people generally have monthly options to leave for Original Medicare with a drug plan. Ask before you change, since your Medicaid benefits may be affected.

Before calling anyone, gather your Medicare card, your Medicaid ID, the plan card, a list of your doctors and medications, and any letters you have received. Write down the date, the name of each person you speak with and a reference number if they give one.

Frequently Asked Questions

Can I have a D-SNP and a Medigap policy at the same time?

No. A Medigap policy only works with Original Medicare, and a D-SNP is a Medicare Advantage plan. If you leave a D-SNP for Original Medicare, your Medigap rights depend on your state and your health history.

Do D-SNPs have a monthly premium?

Many D-SNPs charge no premium beyond what Medicaid or a Medicare Savings Program covers, though that varies. Check the plan’s details each year, since benefits and premiums change.

Does a D-SNP replace my Medicaid?

No. You keep your Medicaid coverage. A D-SNP coordinates your Medicare and Medicaid benefits, and fully integrated plans may deliver both through one company, but your Medicaid eligibility is still determined by your state.

Can I leave a D-SNP any time?

Dual-eligible people generally have a monthly option to go back to Original Medicare with a drug plan. The exact options depend on your situation and the plan type, so check before you make a change.

Is a D-SNP the same as long-term care coverage?

Not by itself. Fully integrated plans in some states cover long-term services and supports through Medicaid, but a basic D-SNP does not. For background, see our page on whether Medicare covers long-term care.
