What are D-SNPs (Dual Special Needs Plans)?
D-SNPs are a type of Medicare Advantage plan designed specifically for people who have both Medicare and Medicaid. They coordinate Medicare and Medicaid benefits in one plan. They're voluntary, not mandatory.

What are D-SNPs (Dual Special Needs Plans)?
D-SNPs (Dual Special Needs Plans) are Medicare Advantage plans designed exclusively for dual-eligibles. They coordinate Medicare and Medicaid in one plan and often add extras like dental, vision, transportation, and care coordination. They're voluntary — Original Medicare paired with Medicaid is also a valid path.
D-SNPs are complicated, the marketing is aggressive, and the right answer is genuinely state-specific. Get free unbiased help before you sign anything.
Free help from licensed Medicare advisors
Chapter Medicare offers free help from licensed Medicare advisors who can walk you through D-SNP options in your state without pushing a specific plan. They're a partner — not a replacement for SHIP, which is the federally funded unbiased counseling program every state has. Use both. Never pay for plan-comparison advice. And never enroll because someone called you out of the blue.
Here's what to do, in 4 steps.
Here's what I tell people who think they want a D-SNP. Confirm dual-eligibility first. Compare options on Medicare.gov. Get free SHIP counseling. And if anyone cold-calls you about a D-SNP, hang up — that's federally prohibited.
1. Confirm you're dual-eligible first
D-SNP enrollment requires dual-eligibility for both Medicare and Medicaid. Check your Medicare card and your Medicaid card. If you're unsure of your category (full dual, QMB, SLMB, QI), call your state Medicaid agency before comparing plans.
Dual-eligible explainer ›2. Compare D-SNPs on Medicare.gov Plan Finder
Medicare's official Plan Finder is the unbiased source for plans available in your ZIP code. Filter for Medicare Advantage Special Needs Plans. Compare benefits, networks, and Star Ratings. Don't pay for plan-comparison advice from anyone else.
Medicare Plan Finder ›3. Get free SHIP counseling at
Every state has a State Health Insurance Assistance Program (SHIP). SHIP counselors are federally funded, unbiased, and trained on dual-eligible plan options. They won't push a specific plan because they don't sell anything. Call before you enroll.
SHIP National Network ›4. Hang up on cold-call D-SNP solicitations
Federal Medicare marketing rules prohibit any agent, broker, or carrier from cold-calling, texting, or showing up at your door about D-SNP enrollment without your prior express permission. If it happens, hang up. Then report it to 1-800-MEDICARE. Never give out your Medicare number on an unsolicited call.

Which of these sounds more like you?
D-SNPs sit at the intersection of Medicare, Medicaid, and Medicare Advantage marketing rules. The right move depends on your state, your dual-eligibility category, and whether you value integration or provider flexibility.
I'm dual-eligible and considering a D-SNPWeighing integration vs. flexibility
Both paths work. A D-SNP gives you one card, one plan, one care manager, and often extras like dental and transportation. Original Medicare paired with Medicaid gives you nationwide provider access and Medicaid handling cost-sharing as a Qualified Medicare Beneficiary or full dual.
The right answer is genuinely state-specific. The integration level available where you live, your dual-eligibility category, and how often you travel all matter. Get free unbiased counseling before you decide.
I'm a flashlight, not a courtroom. Both D-SNPs and Original Medicare with Medicaid are valid paths. Don't pay for plan-comparison advice — SHIP and Medicare.gov are free.
I got a cold call about a D-SNPOr a text, or a knock at the door
Hang up. Don't engage. Don't give out your Medicare number, your Medicaid number, your Social Security number, or your date of birth. Federal Medicare marketing rules prohibit cold-calling, cold-texting, and door-to-door solicitation about D-SNP enrollment without your prior express permission.
Report the call to 1-800-MEDICARE. The agent or carrier behind that call may be operating in violation of CMS rules.
Don't get caught by this — cold-calling, cold-texting, or door-to-door D-SNP solicitation without your prior permission is federally prohibited. Hang up, then report to 1-800-MEDICARE. Real help comes through SHIP, Medicare.gov, or a licensed advisor you contacted first.
I live in a state with mandatory D-SNP enrollmentSome states default full duals into a D-SNP
A handful of states require full dual-eligibles to enroll in a D-SNP, with an opt-out provision. The mechanics vary: passive enrollment with a notification window, default enrollment at Medicaid renewal, or aligned enrollment with a Medicaid managed care plan.
If you got a notice you don't understand, call your state Medicaid agency and SHIP. Don't ignore the letter — the deadline to opt out is usually short.
I want to switch D-SNPsI'm already in one but it's not working
Dual-eligibles get a Special Enrollment Period that allows D-SNP changes once per quarter during the first three quarters of the year (January-March, April-June, July-September). The Annual Enrollment Period (October 15-December 7) also applies.
If the network doesn't include your doctor, the formulary excludes a medication you need, or care coordination isn't actually happening, switching is a normal move. Call SHIP first to compare alternatives.
I need long-term services and supportsHome care, nursing facility, or community LTSS
HIDE-SNPs (Highly Integrated D-SNPs) and FIDE-SNPs (Fully Integrated D-SNPs) include some level of long-term services and supports through their Medicaid managed care contract. The exact LTSS coverage depends on your state's Medicaid program and the integration tier.
A Coordination-Only D-SNP doesn't bundle LTSS — you'd still get those benefits through fee-for-service Medicaid or your state's HCBS waiver program. This is exactly the kind of question SHIP is built to answer for your state.
I'm a flashlight, not a courtroom. LTSS coverage inside a D-SNP varies by state and integration tier. Talk to SHIP at about your specific options — they know what HIDE-SNPs and FIDE-SNPs operate where you live.
I prefer Original Medicare + MedicaidMore provider flexibility, two cards
This is a perfectly valid path. With Original Medicare you can see any provider nationwide who accepts Medicare — no network restrictions. Medicaid then handles your Part A and Part B cost-sharing as a Qualified Medicare Beneficiary or full dual, and Extra Help (LIS) covers most Part D costs.
The tradeoff: you don't get the integrated extras (dental, vision, transportation, OTC allowances) that some D-SNPs include. But provider flexibility is the bigger value for many dual-eligibles, especially if you travel or have specialists across state lines.
I'm helping a parent compare D-SNPsAdult child or caregiver
You'll need their Medicare card, their Medicaid card, and their state's category of dual-eligibility (full dual, QMB, SLMB, or QI). Have their list of doctors and medications ready before you call.
Then call SHIP together at . SHIP counselors will walk through their state's D-SNP options without pushing a specific plan. If your parent has cognitive decline, ask about a representative payee or authorized representative status before the call — SHIP can talk to you directly only with that authorization in place.
My situation is differentNone of the above quite fits
D-SNPs sit at the crossroads of Medicare, Medicaid, and Medicare Advantage marketing rules — there are a lot of edge cases. Maybe you're under 65 with SSDI and dual-eligibility. Maybe you're a Native American with both IHS coverage and dual eligibility. Maybe you're considering moving states. Maybe you're losing Medicaid and need to know what happens to a D-SNP.
For any of those, SHIP at is built exactly for the messy state-specific cases. They're free, unbiased, and trained on dual-eligibility. Don't try to figure it out alone.
Programs that travel alongside D-SNP decisions
D-SNP enrollment touches several other programs. If you qualify for a D-SNP, you probably qualify for a Medicare Savings Program and Extra Help too — and you may have choices between Original Medicare with Medigap, regular Medicare Advantage, or a D-SNP. Here are the related decisions.
Dual-Eligible Medicare and Medicaid
If you have both Medicare and Medicaid, you may qualify as dual-eligible. Dual-eligibility is the prerequisite for D-SNP enrollment and unlocks Medicare Savings Programs, Extra Help, and integrated plans.
Medicare Savings Programs (QMB, SLMB, QI)
If your income is at or below 135% of the federal poverty level, you may qualify for a Medicare Savings Program. QMB pays Part A and Part B premiums and cost-sharing; SLMB and QI pay Part B premiums.
Extra Help / Low-Income Subsidy (LIS)
If your income is at or below 150% of the federal poverty level, you may qualify for Extra Help with Part D drug costs. Full duals and Medicare Savings Program enrollees are automatically deemed eligible.
Medicare Advantage Explained
D-SNPs are a type of Medicare Advantage plan. If you're considering any Medicare Advantage plan, the same enrollment periods, network rules, and Star Ratings apply.
Original Medicare vs. Medicare Advantage
If you're weighing a D-SNP against keeping Original Medicare, the broader Original-vs-Advantage tradeoffs apply: provider flexibility versus network bundling, separate Medigap versus included extras.
Medicaid Overview
If your Medicaid eligibility is still in flux, that affects D-SNP enrollment too. D-SNP enrollment requires active Medicaid; loss of Medicaid triggers a grace period and possible disenrollment from the D-SNP.
Everything people ask me about D-SNPs
What is a D-SNP?
A D-SNP, or Dual Special Needs Plan, is a type of Medicare Advantage plan designed exclusively for people who are dual-eligible for both Medicare and Medicaid. D-SNPs are defined at 42 CFR § 422.2 and must coordinate Medicare and Medicaid benefits, hold a contract with the state Medicaid agency, and meet integration criteria set by CMS.
How is a D-SNP different from a regular Medicare Advantage plan?
A D-SNP enrolls only dual-eligibles, has a state Medicaid contract, and is required to coordinate Medicaid services with Medicare. A regular Medicare Advantage plan accepts any Medicare-eligible enrollee and has no Medicaid coordination obligation. D-SNPs typically offer more extras (dental, vision, transportation, OTC allowance) because the plan can use Medicaid funding to subsidize them.
What does a D-SNP cover?
Every D-SNP covers all of Medicare Part A (hospital), Part B (medical), and Part D (drugs). Beyond that, coverage varies by integration tier and state. HIDE-SNPs and FIDE-SNPs include some Medicaid benefits like long-term services and supports and behavioral health. Many D-SNPs add dental, vision, hearing, transportation, OTC allowances, and care coordination.
Are D-SNPs free?
For most full dual-eligibles and Qualified Medicare Beneficiaries, the D-SNP premium is effectively zero because Medicaid pays the Part B premium and any plan premium tied to Medicare cost-sharing. Cost-sharing inside the plan is typically minimal for full duals. Partial duals (SLMB, QI) may have some out-of-pocket costs depending on plan design — always verify plan-specific costs on Medicare.gov.
Who is eligible for a D-SNP?
You must be entitled to Medicare Part A, enrolled in Part B, and eligible for medical assistance under your state's Medicaid program. The exact dual-eligibility category that qualifies (full dual, QMB, SLMB, QI) depends on the specific D-SNP and your state's contract. Some D-SNPs accept partial duals; some restrict to full duals only.
Should I choose a D-SNP or stay with Original Medicare plus Medicaid?
Both paths work. A D-SNP gives you one card, one plan, integrated care coordination, and often extras. Original Medicare plus Medicaid gives you nationwide provider flexibility (any provider who accepts Medicare) with Medicaid handling cost-sharing. There is no universal best choice — it depends on your state, your dual-eligibility category, and how you use care. Talk to SHIP for free unbiased counseling.
Can I switch D-SNPs?
Yes. Dual-eligibles get a Special Enrollment Period that allows D-SNP changes once per quarter during the first three quarters of the year (January-March, April-June, July-September). The Annual Enrollment Period (October 15-December 7) also applies. You can also drop a D-SNP and return to Original Medicare with Medicaid using these same windows.
What if someone cold-calls me about a D-SNP?
Hang up. Federal Medicare marketing rules under CMS's Medicare Communications and Marketing Guidelines prohibit any agent, broker, or carrier from cold-calling, cold-texting, or showing up at your door about D-SNP enrollment without your prior express permission. Report the call to 1-800-MEDICARE. Never give your Medicare number to an unsolicited caller.
What's the difference between Coordination-Only, HIDE-SNP, and FIDE-SNP?
These are CMS integration tiers. A Coordination-Only D-SNP meets the minimum integration requirement at 42 CFR § 422.107(d). A HIDE-SNP (Highly Integrated D-SNP) has a Medicaid managed care contract covering long-term services and supports or behavioral health. A FIDE-SNP (Fully Integrated D-SNP) provides Medicare and Medicaid benefits under a single entity holding both contracts — the most integrated tier, with required LTSS and (for plan year 2025+) behavioral health, home health, and certain DME.
Where do I get free unbiased help?
Two places. First, your State Health Insurance Assistance Program (SHIP) at — federally funded, unbiased, available in every state. Second, Medicare's Plan Finder at Medicare.gov — the official comparison tool. Chapter Medicare also offers free help from licensed advisors. Whichever you use, never pay for plan-comparison advice.
