Dual Eligible Special Needs Plans: Medicare & Medicaid

A Dual Eligible Special Needs Plan (D-SNP) is a Medicare Advantage plan built for people who qualify for both Medicare and Medicaid. Dual eligible special needs plans Medicare Medicaid coverage combines both programs into one plan, often with $0 or very low out-of-pocket costs and extra benefits Original Medicare does not include on its own, such as dental, vision, hearing, and an over-the-counter allowance.

According to the National Council on Aging, roughly 13.6 million Americans held both Medicare and Medicaid coverage as of 2026, and D-SNP enrollment grew from 2.2 million people in 2018 to about 6.0 million in 2026. That growth shows how many dual-eligible beneficiaries are choosing one coordinated plan over managing Medicare and Medicaid separately.

This guide covers who qualifies for a D-SNP, what these plans cover, how costs work, and how to enroll in 2026.

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 rules are set by each state and are 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, a partial program like a Medicare Savings Program, or another eligibility category, affects which D-SNPs you can join and what extra 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 may also qualify for a Medicare Savings Program, which can help with premium costs and other coverage gaps 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, such as 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 differ.

What Do D-SNPs Cover?

D-SNPs must cover everything Original Medicare covers, including hospital stays, doctor visits, lab work, preventive care, and other medically necessary services. Most plans also coordinate with your Medicaid benefits and add extra benefits not available under standard Medicare.

Prescription Drug Coverage

All D-SNPs include built-in Medicare Part D prescription drug coverage. Many plans offer $0 copays on 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.

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 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 lets members with qualifying chronic conditions, such as diabetes, heart failure, or chronic lung disease, 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 affects 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 practical advantage 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 hand off to your D-SNP is another area where your coordinator can help.

Care coordination is also useful when other programs are in the picture. If you receive VA health care, it helps to know how a D-SNP fits alongside Medicare and veterans benefits. And because Medicaid eligibility and Medicare enrollment intersect closely, our guide to Medicare and Medicaid covers how the two programs work together outside of a D-SNP.

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.

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.
• 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 of the year (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 the standard windows.
