Dual Eligible Special Needs Plans: Medicare & Medicaid
July 3, 2026
What Is a Dual Eligible Special Needs Plan (D-SNP)?
A Dual Eligible Special Needs Plan (D-SNP) is a type of Medicare Advantage plan built specifically for people who have both Medicare and Medicaid. If you qualify for both programs, a D-SNP brings your coverage together into one coordinated plan, often with $0 or very low out-of-pocket costs and extra benefits that Original Medicare does not offer on its own.
As of 2026, roughly 13.6 million Americans hold both Medicare and Medicaid, and enrollment in D-SNPs has grown sharply, from 2.2 million people in 2018 to 6.0 million in 2026, according to the National Council on Aging. That growth reflects how much these plans can reduce the confusion of managing two separate programs at once.
Below you will find a plain-language breakdown of who qualifies, what D-SNPs cover, how costs work, and how to enroll in 2026.
D-SNPs at a Glance
Who Qualifies for a D-SNP?
You must meet two requirements to join a Dual Eligible Special Needs Plan:
- You must be enrolled in Medicare Part A and Part B (Original Medicare)
- You must also have Medicaid coverage through your state
Medicaid eligibility is set by each state and is generally based on income and assets. Many Medicare beneficiaries qualify because their income falls below their state's limit. Your level of Medicaid coverage, full Medicaid, partial programs like a Medicare Savings Program, or another eligibility category, affects which D-SNPs you can join and what additional benefits you receive.
If you are unsure whether you have Medicaid, contact your state Medicaid agency or call 1-800-MEDICARE (1-800-633-4227). You can also look into whether you qualify for a Medicare Savings Program, which can help with medicare coverage gaps and premium costs even if you do not have full Medicaid.
People who qualify for full Medicaid and Medicare are sometimes called “full dual eligibles.” Those with partial Medicaid benefits, like help paying Medicare premiums, are called “partial dual eligibles.” Both groups may be able to enroll in a D-SNP, though available plans and extra benefits may differ.
What Do D-SNPs Cover?
D-SNPs must cover everything that Original Medicare covers, including hospital stays, doctor visits, lab work, preventive care, and medically necessary services. Most plans also coordinate with your Medicaid benefits and layer on extra benefits not available under standard Medicare.
Prescription Drug Coverage
All D-SNPs include built-in Part D prescription drug coverage. Many plans feature $0 copays for a wide range of covered medications and no annual deductible for covered Part D drugs. Because Medicaid typically acts as a secondary payer after Medicare, your remaining drug costs can be reduced significantly or eliminated entirely.
Routine Dental, Vision, and Hearing
Original Medicare generally does not cover routine dental care, vision exams, eyeglasses, or hearing aids. Most D-SNPs include at least some of these benefits, though the scope varies by plan and state.
Over-the-Counter Allowance
Many D-SNPs provide a monthly allowance for over-the-counter (OTC) items such as vitamins, pain relievers, and first-aid supplies. Some plans offer a broader benefit called the Special Supplemental Benefit for the Chronically Ill (SSBCI), which allows members with qualifying chronic conditions, such as diabetes, heart failure, or chronic lung disorders, to use their allowance for groceries, utility bills, or other household essentials.
Transportation, Meals, and Home Support
Non-emergency medical transportation to appointments, meal delivery after a hospital stay, and in-home support services are common extras in D-SNPs. What is available depends on your specific plan and the state you live in.
Key D-SNP Benefits at a Glance
Coordinated Coverage
One plan manages both your Medicare and Medicaid benefits, reducing paperwork and confusion.
Low or No Cost-Sharing
Medicaid covers costs Medicare does not pay, so many services cost you little or nothing out of pocket.
Built-In Part D
Prescription drug coverage is included in every D-SNP, with $0 copays available on many medications.
Extra Benefits
Routine dental, vision, hearing, OTC allowances, and meal delivery are common D-SNP additions.
Care Coordinator
A dedicated coordinator helps you arrange services, schedule appointments, and navigate both programs.
Quarterly Switch Rights
Dual-eligible beneficiaries can switch D-SNPs once per quarter during the first nine months of the year.
Types of D-SNPs: Standard, HIDE-SNP, and FIDE-SNP
Not all D-SNPs integrate Medicare and Medicaid to the same degree. There are three main types, and the level of coordination can affect how seamless your experience feels day to day.
Standard D-SNP
A standard D-SNP coordinates Medicare and Medicaid benefits but may manage them through somewhat separate channels. The plan contracts with Medicare and has a formal relationship with your state's Medicaid program, but you may still receive some Medicaid services through a different entity.
HIDE-SNP (Highly Integrated Dual Eligible Special Needs Plan)
A HIDE-SNP achieves a higher level of coordination. These plans have a formal arrangement to manage both Medicare and at least some Medicaid services through a more unified care model, meeting integration standards set by the Centers for Medicare & Medicaid Services (CMS).
FIDE-SNP (Fully Integrated Dual Eligible Special Needs Plan)
A FIDE-SNP is the most integrated option. It covers both Medicare and full Medicaid benefits through a single plan, giving you one point of contact for nearly all your health coverage. FIDE-SNPs are available in select states and require a contract with the state for Medicaid managed care.

The Role of a Care Coordinator in a D-SNP
One of the most practical advantages of a D-SNP is access to a care coordinator, often a nurse or social worker, who helps you manage your health and coverage. Care coordinators can schedule appointments, arrange transportation, connect you with community services, and explain what your plan covers.
For people managing multiple chronic conditions or navigating both Medicare and Medicaid for the first time, this support can reduce significant stress. If you are transitioning off a job-based plan, understanding how medicare and employer coverage hands off to your D-SNP is another area where your coordinator can walk you through the details.
Care coordination is also valuable when other programs are in the picture. If you receive VA health care, it is worth knowing how a D-SNP fits alongside medicare and veterans benefits. And if you are thinking about how your health coverage connects to retirement income, see how medicare and social security work together.

How to Enroll in a D-SNP in 2026
Confirm your dual eligibility
Make sure you are enrolled in Medicare Part A and Part B and have active Medicaid coverage. Contact your state Medicaid agency or call 1-800-MEDICARE if you are unsure of your Medicaid status.
Find D-SNPs available in your area
Use the Medicare Plan Finder at medicare.gov or call 1-800-MEDICARE (1-800-633-4227) to search for D-SNPs at your ZIP code. Plan availability varies by state and county.
Compare plan benefits carefully
Review each plan's prescription drug formulary, dental and vision benefits, OTC allowance, and provider network. Confirm that your current doctors and preferred pharmacy are in-network before enrolling.
Choose the right enrollment window
Enroll during your Initial Enrollment Period (7 months around your 65th birthday), the Annual Open Enrollment Period (October 15 through December 7), or a qualifying Special Enrollment Period. Dual-eligible beneficiaries can also switch plans once per quarter January through September.
Enroll and meet your care coordinator
Enroll online at medicare.gov, by calling 1-800-MEDICARE, or directly through the plan. Once your coverage begins, contact the plan to set up care coordination and learn about all your available benefits.
You Can Switch D-SNPs Every Quarter
If you have both Medicare and Medicaid, you are not locked into a D-SNP for the full year. You can switch to a different D-SNP once per calendar quarter during January through September using the Dual Eligible Special Enrollment Period. If a plan is not meeting your needs, you have the right to change.
What Do D-SNPs Cost?
For most dual-eligible beneficiaries, D-SNPs come with little to no out-of-pocket cost. Here is how the cost structure typically works:
- Monthly premiums: Many D-SNPs have $0 monthly premiums, though some plans may charge a small amount depending on your state and plan design.
- Copays and coinsurance: Medicare pays its share of covered services first. Medicaid then acts as a secondary payer and typically covers what Medicare does not pay, often resulting in $0 cost-sharing for you.
- Prescription drugs: Many D-SNPs offer $0 copays on covered medications with no annual deductible for covered Part D drugs.
Your actual costs depend on your specific plan, your Medicaid eligibility category, and your state's Medicaid rules. Full dual eligibles, those with complete Medicaid coverage, generally pay the least. Partial dual eligibles may have some cost-sharing for certain services.
It is also important to stay cautious about unsolicited contacts promoting D-SNPs. Knowing how to spot common medicare scams helps you recognize when someone may be pressuring you into a plan that is not right for your situation.
Enrollment Periods for D-SNPs in 2026
D-SNPs follow Medicare Advantage enrollment rules, with added flexibility for dual-eligible beneficiaries. Key windows to know:
- Initial Enrollment Period (IEP): A 7-month window beginning 3 months before the month you turn 65, including your birthday month, and ending 3 months after. This is the standard first-entry point for most people joining Medicare.
- Annual Open Enrollment Period: October 15 through December 7 each year. Coverage for the plan you choose starts January 1 of the following year.
- Medicare Advantage Open Enrollment Period: January 1 through March 31. You can switch Medicare Advantage plans or return to Original Medicare during this window.
- Dual Eligible Special Enrollment Period (DE-SEP): If you have both Medicare and Medicaid, you can switch D-SNPs once per quarter during the first three quarters (January through September).
- Special Enrollment Periods (SEPs): Life events such as losing Medicaid, moving to a new service area, or leaving a nursing facility can trigger an SEP that lets you change plans outside standard windows.
Your State Health Insurance Assistance Program (SHIP) can walk you through your specific enrollment options at no charge. You can also review D-SNP plans available in your area at medicare.gov/plan-compare.

Frequently Asked Questions
A D-SNP is a type of Medicare Advantage plan designed for people who have both Medicare and Medicaid. It brings both programs together into one coordinated plan, typically with lower out-of-pocket costs and extra benefits like dental, vision, hearing, and built-in prescription drug coverage.
You qualify if you are enrolled in Medicare Part A and Part B and also have Medicaid through your state. Contact your state Medicaid agency or call 1-800-MEDICARE (1-800-633-4227) to confirm your Medicaid status. Both full and partial dual eligibles may be eligible, though available plans and benefits differ by eligibility category.
A D-SNP is a specialized Medicare Advantage plan that requires Medicaid enrollment. It must formally coordinate benefits with Medicaid, always includes Part D drug coverage, and typically provides a dedicated care coordinator. Standard Medicare Advantage plans do not require Medicaid and generally do not offer that level of program integration.
Many D-SNPs have $0 monthly premiums. For most covered services, Medicaid acts as a secondary payer after Medicare and typically covers remaining costs, often resulting in $0 copays or coinsurance. Your actual costs depend on your plan, state, and Medicaid eligibility category. Full dual eligibles generally pay the least out of pocket.
A care coordinator, often a nurse or social worker, helps you arrange appointments, transportation, and community services, and helps you navigate your benefits. Most D-SNPs include care coordination as a standard feature. Ask any plan you are considering how to reach your coordinator and what specific services are included.
D-SNPs use provider networks similar to other Medicare Advantage plans. Whether your current doctors are in-network depends on the specific plan. Use the Medicare Plan Finder at medicare.gov/plan-compare to check doctor participation before you enroll.
These are more integrated types of D-SNPs. A FIDE-SNP (Fully Integrated Dual Eligible Special Needs Plan) covers both Medicare and full Medicaid benefits through one plan, available in select states. A HIDE-SNP (Highly Integrated Dual Eligible Special Needs Plan) has a formal arrangement to manage Medicare and at least some Medicaid services together, with stronger coordination standards than a standard D-SNP.
If you have both Medicare and Medicaid, you can switch D-SNPs once per calendar quarter during the first nine months of the year (January through September) using the Dual Eligible Special Enrollment Period. You can also switch during the Annual Open Enrollment Period (October 15 through December 7) or if a qualifying life event triggers a Special Enrollment Period.
Joining a D-SNP does not eliminate your VA health care benefits. The VA and Medicare operate as separate programs, and you can use whichever covers a given service best. For more detail, see our guide on medicare and veterans benefits.
