D-SNP Plans in 2026: The Medicare-Medicaid Combo Plan Most Dual Eligibles Don't Know They Qualify For
A D-SNP (Dual Eligible Special Needs Plan) is a type of Medicare Advantage plan built specifically for people who have both Medicare and Medicaid. Most D-SNPs charge a $0 monthly premium and add benefits standard Medicare doesn't cover, such as dental, vision, hearing, over-the-counter allowances, and free transportation. In 2026, full-benefit dual eligibles who join an integrated D-SNP can switch plans once every calendar month.
Key Facts
- D-SNPs available in 2026
- Roughly 1,000 plans nationwide, nearly double the number in 2020 (KFF)
- Share of SNP enrollees in D-SNPs
- About 78% of all Special Needs Plan enrollment is in D-SNPs (KFF)
- Monthly premium
- Most D-SNPs charge $0 — Medicaid often covers the Part B premium too
- Monthly switching right (2026)
- Full-benefit dual eligibles can join an integrated D-SNP once per calendar month (Integrated Care SEP)
- OTC benefit
- ~96% of D-SNPs offer an over-the-counter allowance, vs ~85% of regular MA plans (KFF)
- Transportation
- ~88% of D-SNPs include medical transportation, vs ~36% of regular MA plans (KFF)
What Is a D-SNP? Medicare and Medicaid Under One Roof
A Dual Eligible Special Needs Plan (D-SNP) is a Medicare Advantage plan authorized by CMS specifically for people enrolled in both Medicare and Medicaid. Think of it as a coordinated wrapper: instead of managing two separate programs with two sets of rules, ID cards, and customer-service lines, a D-SNP unifies them into a single plan.
D-SNPs are required to coordinate your Medicare and Medicaid benefits more tightly than a standard MA plan. CMS has been raising the coordination bar — by 2027, fully integrated D-SNPs must issue a single member ID card that works for both programs and conduct one combined health risk assessment.
Who Qualifies for a D-SNP?
To join any D-SNP you must have Medicare Parts A and B, be enrolled in some form of Medicaid, and live in the plan's service area. Beyond that, CMS splits dual eligibles into two groups.
Full-benefit dual eligibles ('full duals') receive comprehensive Medicaid coverage in addition to Medicare. This group has the widest D-SNP options and, in 2026, can use the monthly Integrated Care SEP to switch plans any time of year.
Partial-benefit dual eligibles receive Medicaid help with Medicare cost-sharing (premiums, deductibles, copays) but not full Medicaid coverage. Partial duals can enroll in D-SNPs in most states, but they do not have the monthly switching SEP that full duals enjoy.
2026 D-SNP Benefits: Beyond Standard Medicare
Standard Medicare covers hospital stays, doctor visits, and outpatient services — but not routine dental, eyeglasses, hearing aids, or transportation. D-SNPs routinely fill those gaps.
Per KFF analysis of 2026 plan data, the large majority of D-SNPs offer an over-the-counter (OTC) allowance, medical transportation, and meal benefits after a hospital stay, and many include in-home support or bathroom-safety devices. Exact dollar amounts and covered items vary by plan and state, so compare the Evidence of Coverage for plans in your area.
Most D-SNPs also charge a $0 monthly premium, and for full duals, Medicaid frequently pays the Medicare Part B premium too — so the plan can effectively cost nothing each month.
The 2026 Monthly SEP: Switch Plans Any Month
This is the rule most people on both programs don't know about. As of 2025 and continuing in 2026, CMS created the Integrated Care Special Enrollment Period (SEP), allowing full-benefit dual eligibles to enroll in or switch to an integrated D-SNP once per calendar month, effective the first of the following month.
Under normal MA rules, most people can only change plans during the Annual Enrollment Period (October 15 – December 7). Full duals are different: if you find a better D-SNP or your plan stops serving your area, you can switch on the 1st of virtually any month.
Not every D-SNP qualifies as 'integrated' for this SEP. Verify a plan appears on CMS's list of 2026 Integrated D-SNPs before assuming the monthly SEP applies.
How D-SNPs Have Grown — and Why It Matters
D-SNPs are one of the fastest-growing parts of Medicare — the number of available plans has nearly doubled since 2020. In 2026, roughly 23% of all Medicare Advantage enrollees are in a Special Needs Plan, and about 78% of those are in D-SNPs (KFF).
KFF data also shows the large majority of the net increase in MA enrollment between 2025 and 2026 came from SNPs, mainly D-SNPs. More plans in more areas means more access — and a competitive market that pushes plans to add richer benefits, which works in your favor.
D-SNP vs. Regular Medicare Advantage
A regular MA plan is open to anyone with Medicare; a D-SNP is only for people with both Medicare and Medicaid. Both are run by private insurers approved by CMS, but D-SNPs carry extra federal requirements around care coordination and must contract with your state's Medicaid agency.
In practice, D-SNPs tend to have richer supplemental benefits — especially transportation, OTC allowances, and in-home support — because their enrollees have more complex needs, and they assign dedicated care coordinators. If you qualify for a D-SNP, there is generally little reason to settle for a standard MA plan.
How to Find D-SNP Plans in Your Area
Start at medicare.gov/plan-compare. Enter your ZIP code, choose 'Medicare Advantage,' and filter for Special Needs Plans (SNPs), then look for plans labeled D-SNP. You can compare premiums, formularies, star ratings, and benefits side by side.
You can also call 1-800-MEDICARE (1-800-633-4227), available 24/7, or get free help from a State Health Insurance Assistance Program (SHIP) counselor at shiphelp.org. To use the monthly SEP, confirm the plan appears on CMS's 2026 Integrated D-SNP list before enrolling.

Do I need to apply for a D-SNP separately from Medicaid?
No. You must already be enrolled in Medicaid (or in the process) to join a D-SNP. Once you have both Medicare and Medicaid, you enroll in the Medicare Advantage side through the plan or medicare.gov.
Will a D-SNP cost me anything each month?
Most D-SNPs charge a $0 monthly premium, and for full-benefit dual eligibles Medicaid often pays the Part B premium too, so net monthly cost can be $0. Some services may have copays depending on your state's Medicaid rules, but many full duals have little or no cost-sharing.
Can I keep my current doctors if I switch to a D-SNP?
It depends on the plan's network. Confirm your doctors are in-network before switching. Because full duals can switch plans monthly, you can course-correct quickly if a network issue arises.
What is the difference between a full and partial dual eligible?
A full-benefit dual eligible receives comprehensive Medicaid coverage on top of Medicare; a partial dual eligible only receives Medicaid help with Medicare premiums and cost-sharing. Only full duals qualify for the monthly Integrated Care SEP to switch D-SNP plans any month.
What happens to my D-SNP if I lose Medicaid?
If your Medicaid coverage ends you no longer meet D-SNP eligibility and the plan must disenroll you, but you get a Special Enrollment Period to join a different Medicare Advantage plan or return to Original Medicare. Plans must notify you before disenrollment.
