If you have both Medicare and Medicaid, you may qualify for a Dual Eligible Special Needs Plan, commonly called a D-SNP. A D-SNP is a type of Medicare Advantage plan designed for people who meet specified Medicare and Medicaid conditions. Availability, integration, costs, provider networks, and supplemental benefits vary by plan and location.
This guide explains the parts that are common to D-SNPs and the details you must verify before deciding whether a specific plan fits your needs.
What Is a D-SNP?
A D-SNP (Dual Eligible Special Needs Plan) is a specialized type of Medicare Advantage (Part C) plan that is specifically designed for individuals who are enrolled in both Medicare and Medicaid. Unlike standard Medicare Advantage plans that are open to any Medicare beneficiary, D-SNPs limit enrollment to dual-eligible individuals — allowing them to tailor benefits, formularies, and care coordination specifically for this population.
D-SNPs are offered by private insurance companies approved by Medicare. They must cover Medicare Part A and Part B services, and every Special Needs Plan includes Medicare Part D prescription-drug coverage. A D-SNP is also designed to coordinate with Medicaid, but the degree of integration and the costs Medicaid pays depend on the plan and the person's Medicaid eligibility category.
How D-SNPs Work
When you enroll in a D-SNP, the plan becomes your primary source of Medicare coverage. The plan coordinates your Medicare and Medicaid benefits together, which means:
- Medicare Part A and Part B coverage through the plan
- Medicare Part D prescription-drug coverage
- Care coordination designed for the population the plan serves
- Coordination with Medicaid that varies by plan design and Medicaid eligibility status
Special Needs Plans use a model of care and conduct health-risk assessments to identify member needs. The exact care-management process and member experience vary, so ask who coordinates care, how to reach that person, and what happens when Medicare and Medicaid coverage overlap.
D-SNP Benefits in 2026
Every D-SNP covers Medicare Part A, Part B, and Part D services. Other benefits and member costs vary by plan, county, eligibility category, and plan year:
| Benefit | Typical D-SNP Coverage |
|---|---|
| Monthly Premium | Varies by plan; the Medicare Part B premium may still apply |
| Prescription Drugs | Included, but formulary, pharmacy network, tiers, and cost sharing vary |
| Dental, Vision, and Hearing | May be offered; covered services, networks, frequency, and limits vary |
| Over-the-counter benefit | May be offered; eligible items, vendors, amount, and frequency vary |
| Food or nutrition benefit | Not universal; eligibility and covered items may be restricted |
| Transportation | May be offered with trip, distance, destination, and scheduling limits |
| Care Coordination | Plan-specific model of care and member-support process |
| Member Cost Sharing | Depends on plan design and Medicaid eligibility category |
Who Qualifies for a D-SNP?
To be eligible for a D-SNP, you must meet two requirements:
- Medicare eligibility: You must be enrolled in Medicare Part A and Part B.
- Medicaid eligibility: You must be enrolled in a state Medicaid program.
Medicaid eligibility varies by state, but it is generally based on income and resources. Common qualifications include:
- Income at or below a percentage of the Federal Poverty Level (FPL)
- Limited assets/resources (rules vary by state)
- Age 65+ or disabled
Some people with Medicare and Medicaid also qualify for a Medicare Savings Program, which may help pay Medicare premiums or other cost sharing depending on the program. Eligibility and assistance vary by state and category. Your state Medicaid office and Medicare can confirm your current status.
Types of Dual Eligibility
Not all dual eligibles are the same — and D-SNPs may have different benefit levels depending on your Medicaid status:
- Full-benefit dual eligibility: Medicare plus full Medicaid benefits, subject to state rules.
- Partial-benefit dual eligibility: Medicare plus certain Medicaid help with Medicare costs, such as through a Medicare Savings Program.
- Plan-specific eligibility: A D-SNP may serve only particular dual-eligibility categories. Confirm that the plan accepts your current category.
D-SNP vs. Standard Medicare Advantage
A D-SNP is not automatically the best choice for every person with Medicare and Medicaid. Compare the coordination model, providers, medications, member costs, extra-benefit rules, and service experience:
| Feature | D-SNP | Standard MA Plan |
|---|---|---|
| Medicaid Coordination | Yes — integrated | No |
| Premium | Varies | Varies |
| Care Coordination | Designed for the plan's special-needs population | Plan-specific |
| Drug Costs | Varies by plan and subsidy status | Varies by plan and subsidy status |
| Extra Benefits | Plan-specific | Plan-specific |
| Who Can Enroll | Dual eligibles only | Any Medicare beneficiary |
How to Enroll in a D-SNP
Enrollment opportunities depend on your Medicare and Medicaid status, the type of D-SNP, and whether an integrated plan is available in your area. Special Enrollment Period rules have changed over time, so do not rely on an old quarterly or "any time" summary.
Use Medicare's current Special Enrollment Period guide, call 1-800-MEDICARE, or ask your state Medicaid office to confirm what change you can make and when it would take effect.
How to Find the Best D-SNP Plan
Not every D-SNP is the same, and availability varies by county. When comparing D-SNP plans, consider:
- Benefits package: Compare OTC allowances, dental coverage limits, food benefits, and vision/hearing coverage
- Drug formulary: Make sure your medications are covered at $0 or low cost
- Provider network: Confirm your doctors and preferred hospitals are in-network
- Star rating: Use the rating as one quality signal, not as proof that the plan fits your providers, drugs, costs, or service needs
- Plan type: HMO vs. PPO — HMOs require referrals; PPOs allow more flexibility
Frequently Asked Questions
Can I switch D-SNP plans during the year?
Possibly. The timing depends on your eligibility, the plan type, and current Special Enrollment Period rules. Check Medicare's current rules rather than relying on an older quarterly summary.
Does a D-SNP replace Medicaid?
No. A D-SNP works alongside Medicaid — it does not replace it. The plan coordinates your Medicare benefits and many D-SNPs coordinate certain Medicaid benefits, but your state Medicaid program continues to exist separately.
Do D-SNPs require a referral to see specialists?
It depends on the plan type. Most D-SNPs are HMO plans that require referrals from a primary care physician to see specialists. Some D-SNP PPO plans allow you to see specialists without a referral, though staying in-network typically results in lower costs.
Is there a cost to enroll in a D-SNP?
Premiums and cost sharing vary. You may still owe the Medicare Part B premium unless Medicaid or another assistance program pays it. Verify the plan premium, medical and drug cost sharing, and how your Medicaid category affects those costs.
