A Dual Eligible Special Needs Plan (D-SNP) is a kind of Medicare Advantage plan—also known as Part C—designed for people who are enrolled in both Medicare and Medicaid. Instead of juggling two separate programs on your own, a D-SNP is built to coordinate hospital, medical, and drug coverage together with Medicaid so your care and costs are easier to manage. The exact rules, networks, and benefits still depend on the plan contract and where you live, so you should always review plan documents or speak with a licensed agent before you enroll.
Official overviews of Medicare Advantage are on Medicare.gov — Medicare Advantage (Part C). For how Special Needs Plans fit in, see Medicare.gov — Medicare Special Needs Plans. CMS also publishes dual-eligible program context at CMS — Dual Eligible Special Needs Plans (D-SNPs).

Medicare Advantage plans are offered by private insurance companies that contract with Medicare. They must cover everything Original Medicare (Parts A and B) covers, and most include Part D drug coverage. A D-SNP is a Special Needs Plan—a Medicare Advantage option with extra focus on members who have both Medicare and Medicaid. If you want a broader picture of Part C before diving into D-SNPs, our Medicare Advantage overview walks through how these plans work for Brooklyn and NYC residents.
D-SNPs are meant for people who are dual-eligible: they qualify for Medicare (usually by age, disability, or certain conditions) and for Medicaid through New York’s income and asset rules. Medicaid in New York can include different levels of help (for example, full Medicaid or programs that only pay certain Medicare costs). Your Medicaid category can affect which D-SNPs you can join and what cost-sharing looks like, so “dual-eligible” is not one-size-fits-all.
You typically need active enrollment in both Medicare and Medicaid to join a D-SNP. Medicare eligibility follows federal rules (for example, turning 65 with enough work credits, or qualifying through disability). Medicaid eligibility in New York—including New York City and Brooklyn—is set by state guidelines and may consider income, resources, household size, and other factors. Because those details change and depend on your situation, use NY State of Health and the New York State Department of Health — Medicaid pages to confirm current requirements rather than relying on informal summaries alone.
Most people first get Medicare Part A and Part B around age 65 or when they meet disability rules. You must generally enroll in Part A and Part B (or otherwise have Medicare) to choose a Medicare Advantage plan, including a D-SNP. For official steps and timelines, start with Medicare.gov — Get started with Medicare and When does Medicare coverage start?. Our Medicare enrollment checklist lists practical steps so you do not miss important windows.
If you need help with Part D costs, read about Extra Help paying for prescription drugs from Social Security (official program information).
Medicaid is a joint federal and state program. In New York, eligibility and benefits can differ from other states and even by county or program. That matters for D-SNPs because plans are offered in specific service areas and may coordinate differently with state Medicaid. If you move between boroughs or out of state, your plan options and Medicaid status may change—always report address changes to Medicare and Medicaid and review whether your D-SNP still works for you.
If you are unsure whether you have full Medicaid, partial help, or only Medicare, start with official sources: your Medicaid notice, NY State of Health, or a local Medicaid office. You can also use SHIP — the free, state-based State Health Insurance Assistance Program (find local SHIP help) — or our Community Resource Hub. For how Medicaid connects to Medicare topics on our site, see Medicaid information. A licensed agent can explain how D-SNPs work among plans we offer in your area, but only New York can confirm Medicaid eligibility.
To compare broader options on your own, use the official Medicare Plan Finder at Medicare.gov (you can filter and review plans available in your ZIP code).
A D-SNP must cover Medicare-covered services the same way other Medicare Advantage plans do, and it is structured to align with Medicaid. Many members see lower copays or $0 premiums for certain services, but out-of-pocket costs still depend on the plan, your Medicaid level, and the providers you use. Extra benefits—such as dental, vision, hearing, transportation, or over-the-counter (OTC) allowances—vary widely by plan and year; read the Evidence of Coverage for anything you rely on.
In simple terms, Medicare often pays first for Medicare-covered care, and Medicaid may help with premiums, cost sharing, or services Medicaid covers, depending on your eligibility. A D-SNP is designed so the plan and Medicaid can work in a more coordinated way than picking a random Medicare Advantage plan that is not built for dual-eligible members. Coordination details are plan-specific; ask how prior authorization, specialists, and prescriptions are handled under both programs.
Plans may advertise supplemental benefits beyond basic Medicare. Examples sometimes include OTC cards, meal support after hospital stays, fitness, or non-emergency medical transportation—but not every plan includes every benefit, and limits apply. Treat marketing materials as a starting point only; confirm coverage in writing for the plan year you are considering.

You enroll in a D-SNP through the same general Medicare Advantage enrollment paths as other Part C plans, but you must stay eligible for both Medicare and Medicaid to remain in a D-SNP. If you lose Medicaid, you may need to change to a different type of Medicare coverage during an election period. Dates below follow the annual pattern Medicare uses; confirm the current year on Medicare.gov.
The Annual Enrollment Period runs from October 15 to December 7 each year. During AEP, people with Medicare can generally join, switch, or drop Medicare Advantage and Part D plans; changes usually take effect January 1 of the next year. The Medicare Advantage Open Enrollment Period runs from January 1 to March 31 each year for people already in a Medicare Advantage plan; rules limit what you can change, so check Medicare’s OEP rules for your situation.
A Special Enrollment Period (SEP) may open when you have certain life changes—for example, gaining or losing Medicaid, moving out of a plan’s service area, or other qualifying events listed by Medicare. SEP rules are specific to the event; if your Medicaid status changes, act quickly to avoid a gap in coverage and to see which D-SNPs (if any) you can join mid-year.
Illustration only — always confirm current-year dates on Medicare.gov.
Other Medicare Advantage plans may be open to anyone who has Part A and Part B and lives in the service area, without requiring Medicaid. A D-SNP is only for dual-eligible members and is built around Medicaid coordination and cost-sharing rules that match that population. Networks (HMO vs PPO), drug formularies, and extra benefits still differ plan by plan—compare star ratings, provider directories, and drug coverage for your doctors and medications. For a deeper comparison of how Part C works in general, start with our D-SNP plans page and Medicare Advantage guide.
- Eligibility: D-SNP requires Medicare + Medicaid (dual-eligible); many other MA plans do not.
- Focus: D-SNPs emphasize coordination with Medicaid; general MA plans may not.
- Benefits and costs: Both types vary by plan; always read the Summary of Benefits and Evidence of Coverage.
These resources are from Medicare, CMS, or other official sources. They can help you double-check what you read here—benefits and rules still depend on your plan and situation.

Yes. Many older adults and people with disabilities have both. When you do, you may be dual-eligible and could qualify for a D-SNP if one is offered in your county and you meet the plan’s rules. Confirm Medicaid status with New York and Medicare enrollment with Medicare.gov.
A DSNP (usually written D-SNP) is a Dual Eligible Special Needs Plan—a Medicare Advantage option for people with both Medicare and Medicaid. It is designed to help coordinate benefits. Plan details vary by location and contract year.
You generally need Part A and Part B and qualifying Medicaid through New York. Use official resources such as NY State of Health or your Medicaid documents, then check which D-SNPs serve your ZIP code for the year you are enrolling.
They may. Many plans offer supplemental benefits like dental, vision, or transportation, but coverage limits and network rules differ. Always check the plan’s official materials for the year you are enrolling—not just ads or summaries.
Maybe. Medicare Advantage plans, including D-SNPs, use provider networks. Before you enroll, search the plan’s provider directory for your primary care doctor and specialists, and ask whether they accept that plan for the dates you need care.
A D-SNP is only for dual-eligible members and focuses on Medicaid coordination and related cost-sharing. Regular Medicare Advantage may be available without Medicaid but will not replace the D-SNP model of support for dual-eligible enrollees.
