D-SNP basics

What is a D-SNP in New York, and who do you call?

Last reviewed: September 28, 2026 · Educational, vendor-neutral, not a government site

In short: a D-SNP (Dual Eligible Special Needs Plan) is a Medicare Advantage plan for people who have both Medicare and Medicaid. It covers doctor, hospital, and prescription drug care. In New York it is often paired with a Medicaid plan from the same company. Joining one is optional unless you want New York’s MAP or IB-Dual plans.

NYS DOH IB-Dual guide

According to the New York State Department of Health, a D-SNP includes doctor, hospital, and prescription drug coverage. Some plans may also offer extra benefits such as transportation, home-delivered meals, or over-the-counter (OTC) allowances. Exact extras vary by plan and year. Since January 1, 2025, the state has required D-SNPs to include dental benefits as a Medicare supplemental benefit.

Who can join (high level)

In general, you may be able to enroll in a D-SNP if you:

  • Have Medicare (typically Part A and Part B), and
  • Have Medicaid benefits (full Medicaid or certain levels of help), and
  • Live in the plan’s service area

Only an official enrollment process can confirm whether a specific plan will accept you. This article does not say you qualify for any plan.

Why people look at D-SNPs

Having Medicare and Medicaid at the same time can mean two sets of rules, cards, and phone numbers. A D-SNP is designed so one health plan helps coordinate Medicare benefits, and, depending on the arrangement in New York, work more closely with your Medicaid coverage.

Coordination does not automatically mean every doctor you see today is in the new network, or that every benefit stays the same. Always compare the plan’s Evidence of Coverage and provider directory, or ask a counselor to help you check.

Dual eligible plans in New York: D-SNP, IB-Dual, MAP, and PACE

New York describes several ways dual eligibles may get more integrated care, including D-SNPs and programs such as IB-Dual (for many people who do not need long-term community-based services beyond certain limits) and Medicaid Advantage Plus (MAP) (for some people who need longer-term care supports). Which path fits depends on health needs, county, and current Medicaid enrollment, not on a website quiz.

The state says that if you want MAP or IB-Dual, you must join your health plan’s D-SNP. If you do not, joining a D-SNP is not required. Other options include other Medicare Advantage plans or Original Medicare. MAP requires full Medicaid and a need for at least 120 days of long-term care services and supports.

When you can join or leave a D-SNP

People with Medicare and Medicaid get more chances to change than most people. According to Medicare.gov, if you have Medicaid or Extra Help you can change your drug coverage once a calendar month, including leaving a Medicare Advantage plan for Original Medicare plus a stand-alone drug plan. If you have full Medicaid, you can join or switch to an integrated D-SNP once a calendar month. Changes start the first day of the next month. Confirm your options with HIICAP before you switch.
