A Special Needs Plan (SNP) is a type of Medicare Advantage Plan. Medicare.gov: it provides benefits and services to people with specific severe and chronic diseases, certain health care needs, or who also have Medicaid. SNPs include care coordination and tailor benefits, provider networks, and drug lists (formularies) to the groups they serve.
They are still Advantage plans. They are HMO or PPO (or HMO Point-of-Service) plan types. They cover the same Part A and Part B benefits all Advantage plans cover. All SNPs must include Part D. That last sentence is Medicare.gov, not a sales extra.
This page is not a plan ranking. It does not name carriers. It does not print a star-rating league table.
I have spent 18 years inside consumer marketing and lead generation in insurance and health. That is operator experience, not a counseling credential and not a license.
Who can join
Medicare.gov: you can join an SNP if you meet all of these:
- You have Medicare Part A and Part B.
- You live in the plan's service area.
- You meet the eligibility requirements for one of the three types (or a subset of one of those groups).
CMS publication 12026 (*Understanding Medicare Advantage Plans*) adds that you must be a U.S. citizen or lawfully present in the U.S., the same rule as other Advantage plans.
You can stay enrolled only if you continue to meet the special conditions of the plan. If you lose the qualifying condition, you may get a Special Enrollment Period to join another plan.
Where SNPs are offered: each year, different types may be available in different parts of the country. Insurance companies decide where they do business. SNPs may not be everywhere.
The three types, as Medicare.gov and 12026 print them
Dual Eligible SNP (D-SNP)
You are eligible for both Medicare and Medicaid. D-SNPs contract with your state Medicaid program to help coordinate Medicare and Medicaid benefits.
Some D-SNPs are called integrated D-SNPs. 12026: they combine your Medicare benefits and most or all of your Medicaid benefits through a single plan. All integrated D-SNPs must:
- Give you one member ID card that works for both Medicare and Medicaid.
- Offer a single health risk assessment that covers both programs.
- Provide a care coordinator or case manager and a personal care plan.
- Have one appeals and grievance process for Medicare or Medicaid issues.
Not every D-SNP is integrated. Medicare.gov's Special Enrollment Periods page: if you qualify, you can join or switch to an integrated D-SNP once a calendar month where one is available; the change takes effect the first day of the next month. Contact the plan or 1-800-MEDICARE for a list of integrated D-SNPs. This page does not list them.
D-SNPs are related to, but not the same as, Medicare Savings Programs. MSP can pay Part B premiums. A D-SNP is an Advantage plan for people who have Medicare and Medicaid. Do not treat a D-SNP directory as an MSP eligibility decision.
Chronic Condition SNP (C-SNP)
You have one or more specific severe or disabling chronic conditions. 12026's list:
- Cancer
- Certain autoimmune disorders
- Certain cardiovascular disorders
- Certain chronic and disabling mental health conditions
- Certain chronic gastrointestinal diseases
- Certain chronic lung disorders
- Certain neurological disorders
- Certain severe hematological disorders
- Chronic alcohol use disorder and other substance use disorders
- Chronic heart failure
- Chronic kidney disease and End-Stage Renal Disease (ESRD)
- Dementia
- Diabetes mellitus
- HIV/AIDS
- Stroke
Medicare.gov: C-SNPs can limit membership to a single chronic condition or a group of related chronic conditions. Having a condition on that list does not mean a C-SNP exists in your county. Plan availability varies by geography, SNP type, and enrollment rules.
There is an SEP if you have a severe or disabling condition and a Chronic Care SNP is available for that condition. Medicare.gov: you can join anytime, but once you join, that SEP ends.
Institutional SNP (I-SNP)
12026: you live in the community but need the level of care a facility offers, or you live (or are expected to live) for at least 90 days straight in a facility such as:
- Intermediate care facility
- Long-term care hospital
- Nursing facility
- Psychiatric hospital
- Rehabilitation hospital
- Skilled nursing facility
- Swing bed hospital
- Other facility offering similar long-term health care services whose residents have similar needs
Medicare.gov: if you are interested in an I-SNP and live in a facility, check that the plan has providers that serve people where you live. I-SNP is not a nursing-home payment. Medicare still does not pay long-term custodial care.
All SNPs must include Part D
Medicare.gov's SNP FAQ table: "Do these plans offer Medicare drug coverage (Part D)? Yes. All SNPs must provide Medicare drug coverage (Part D)." 12026 repeats it. You do not join a separate drug plan on top of an SNP.
Premiums vary by plan. Some charge a plan premium in addition to the monthly Part B premium ($202.90 standard in 2026). If you have Medicare and Medicaid, most of the costs may be covered; contact your Medicaid office. This page does not invent a $0-premium SNP.
Networks, referrals, and extra days
Doctor and hospital choice varies by plan. Some SNPs require care in network except emergency care, out-of-area urgent care, or out-of-area dialysis. Some offer out-of-network coverage at a higher cost. Primary-care doctors and specialist referrals: varies by plan. If you have a doctor you like, ask the plan if you can keep them.
SNPs might cover extra services for the groups they serve. Medicare.gov's example: if you have a severe condition like cancer or congestive heart failure and need a hospital stay, an SNP may cover extra days in the hospital. That is a "may." It is not a federal extra-day entitlement, and it is not a reason to rank plans.
Rules that apply to SNPs as Advantage plans
Medicare.gov SNP page:
- Your plan cannot charge more than Original Medicare for certain services like chemotherapy, dialysis, and skilled nursing facility care.
- If your plan gives prior approval for a treatment, that approval must be valid as long as the treatment is medically necessary. The plan cannot ask you to get additional approvals for that treatment.
- If you are getting treatment and switch to a new plan, you will have at least 90 days before the new plan can ask you to get a new prior approval for ongoing treatment.
Those are CMS enrollee protections. They are not a star rating.
If you lose SNP eligibility, Medicare.gov SEP page: your chance to switch starts the month you lose special-needs status and ends when you join another plan or 3 calendar months after the effective date of involuntary disenrollment from the SNP, whichever is earlier. You can join a drug plan or another type of Advantage plan.
Confirm with Medicare.gov, the plan's EOC, and SHIP
- SNP overview: Medicare.gov SNP
- Booklet: Understanding Medicare Advantage Plans (12026)
- Original vs Advantage: this site
- SHIP: shiphelp.org
- 1-800-MEDICARE (TTY 1-877-486-2048)
Ask the plan whether you meet its special-needs rules, whether your doctors and dialysis facility (if you have ESRD) are in network, and read that year's Evidence of Coverage. This page will not pick a plan.
This is education, not advice
An SNP is Advantage with extra eligibility rules. It is not Original Medicare plus extras. Confirm with Medicare.gov, Medicaid (for D-SNPs), the plan, and SHIP. Rules and service areas change each year.
Labeled marketplace placements, when they exist, sit after the last decision section and before FAQ. Until a licensed partner link is live, that slot stays empty. This page will not rank carriers or treat a marketplace quote as a CMS figure.
How SNPs sit next to Original Medicare and regular Advantage
You still have Medicare in an SNP. You get most Part A and Part B from the plan, not from Original Medicare, except hospice (Original Medicare is still billed) and a few other CMS exceptions described in 12026. You still pay the Part B premium unless Medicaid or an MSP pays it.
Regular Advantage plans are open to people with Part A and Part B in the service area, with no special-needs test. SNPs add that test. If you do not meet D-SNP, C-SNP, or I-SNP rules, you cannot join that SNP. You may still join another Advantage plan or stay in Original Medicare.
Enrollment windows are the same calendar as other Advantage plans, plus SNPs' extra SEPs: integrated D-SNP monthly SEP where available; C-SNP SEP if a plan serves your condition (join anytime, then that SEP ends); loss-of-status SEP. AEP remains October 15-December 7. MA OEP (January 1-March 31) is only if you are already in Advantage. Details: enrollment windows.
Care coordination is required language on Medicare.gov: all SNPs give care coordination and tailor formularies. That is not a star-rating table. Read the Evidence of Coverage for prior authorization, referrals, and whether extra hospital days are actually covered for your condition.
If you have Medicaid, ask the state whether a specific D-SNP is integrated and whether you must use it. This page will not name a plan.
What this page will not do
It will not name a D-SNP, C-SNP, or I-SNP. It will not reprint CMS star ratings as a league table. It will not tell you that extra dental or grocery benefits make an SNP "better" than Original Medicare. Extra benefits on Advantage are plan-specific *may* / *most plans* language in CMS booklets. SNPs tailor extras to the group they serve; that is still plan-specific.
It will not treat Medicaid eligibility as automatic D-SNP enrollment. You must have Part A and Part B, live in the service area, and meet that SNP's rules. Availability varies by county each year.
For dual-eligible cost help without joining Advantage, start with Medicare Savings Programs and Extra Help. For chronic conditions without a C-SNP in your area, you still have Original Medicare or other Advantage plans. For facility-level care, read nursing home coverage before you treat an I-SNP as a long-term-care policy. It is not one.
Plan availability, networks, and extra benefits change every year. Read the Annual Notice of Change and Evidence of Coverage. Call 1-800-MEDICARE or SHIP if the brochure and the EOC disagree.
FAQ
Do all SNPs include drug coverage?
Yes. All SNPs must provide Part D. Medicare.gov and 12026.
What are D-SNP, C-SNP, and I-SNP?
D-SNP: Medicare and Medicaid. C-SNP: specified severe or disabling chronic conditions. I-SNP: living in, or needing the level of care of, a listed facility (or expected to for at least 90 days). You must also have Part A and Part B and live in the service area.
Can I join an SNP if I have ESRD?
C-SNPs can include chronic kidney disease and ESRD as qualifying conditions, if such a plan is offered where you live. People with ESRD can join Advantage generally (12026). Check the plan's network for dialysis and transplant providers.
Is a D-SNP a Medicare Savings Program?
No. MSP (QMB/SLMB/QI) is a state program that can pay Medicare premiums and, for QMB, cost sharing. A D-SNP is a Medicare Advantage plan for people who have Medicare and Medicaid. You might have both. They are different applications.
Can I stay in an SNP if I no longer qualify?
No. You can stay only if you continue to meet the plan's conditions. Losing status can open an SEP to join another plan. Confirm with the plan and Medicare.gov.
Medicare.gov and 12026 are the records. Confirm the current text with them.
Do SNPs have a yearly out-of-pocket maximum?
Yes, as Medicare Advantage plans they have a yearly limit on what you pay for covered Part A and Part B services. Once you hit the plan's limit, you pay nothing for those covered services for the rest of the year. Original Medicare alone does not have that yearly cap. The limit amount is plan-specific. This page does not invent one. You still pay the Part B premium unless another program pays it.
If I have QMB, do I need a D-SNP?
Not automatically. QMB is a Medicare Savings Program. A D-SNP is an Advantage plan for people with Medicare and Medicaid. You can have QMB (and Extra Help) and stay in Original Medicare. You can have Medicaid and join a D-SNP if one is offered and you meet its rules. Confirm with the state and SHIP.
