2027 Medicare Special Needs Plan guide

Three Types of Special Needs Plans: D-SNP, C-SNP, and I-SNP

The three types of Special Needs Plans are Dual Eligible SNPs (D-SNPs), Chronic Condition SNPs (C-SNPs), and Institutional SNPs (I-SNPs). Each is a Medicare Advantage plan designed for a specific group, and each has its own eligibility test. This 2027 guide explains who may qualify, what all SNPs have in common, and what to verify before enrolling.

Overview of the three types of Medicare Special Needs Plans: D-SNP, C-SNP, and I-SNP

A Special Needs Plan, or SNP, is not a separate part of Medicare. It is a specialized Medicare Advantage plan. You generally must have Medicare Part A and Part B, live in the plan's service area, and meet the plan's special eligibility requirements. Plan availability, provider networks, drug formularies, costs, and extra benefits can change by county and plan year.

Use this page to identify the category that may fit. Then compare the actual 2027 Evidence of Coverage, Summary of Benefits, provider directory, and formulary for every plan you are considering.

Quick comparison of the three SNP types

The category names describe who can join; they do not guarantee a particular premium, copay, allowance, provider, or extra benefit. Two plans in the same category may work very differently. The comparison below is a starting point, not an enrollment determination.

1. D-SNP: for people with Medicare and Medicaid

A Dual Eligible Special Needs Plan is for someone entitled to Medicare who also qualifies for Medicaid. Medicare and Medicaid are separate programs: Medicare is federal health coverage, while Medicaid is jointly funded by federal and state governments and administered under state rules. A D-SNP is intended to coordinate those two sources of coverage.

“Dual eligible” does not mean that every person receives the same Medicaid benefits. States use different eligibility categories, and a person's category can affect whether Medicaid pays the Medicare Part B premium, Medicare cost-sharing, or additional services. A D-SNP may accept all dual-eligible categories or only specified categories. That is why a current Medicaid card alone does not answer every plan-eligibility or cost question.

What to verify before choosing a D-SNP

  • Your current Medicaid status and eligibility category, not an older determination.
  • Whether the D-SNP accepts that category in your county for 2027.
  • How the plan coordinates claims, authorizations, transportation, long-term services and supports, or other Medicaid benefits that apply to you.
  • Whether your doctors, hospitals, pharmacies, medicines, and preferred care organizations participate.
  • Whether the plan is integrated with the state Medicaid program and what that integration means in practice.

Some D-SNPs provide more integrated Medicare and Medicaid administration than others. Do not assume that joining a D-SNP replaces your Medicaid coverage or that every service moves onto one card. Read the plan's documents and any state Medicaid notices together. If your Medicaid eligibility changes, promptly ask the plan how the change affects enrollment and cost-sharing.

2. C-SNP: for specified chronic conditions

A Chronic Condition Special Needs Plan limits enrollment to people who have one or more severe or disabling chronic conditions addressed by that plan. Federal rules recognize categories of conditions that may support C-SNP design, but a particular plan may focus on one condition or a related group of conditions. Having a common chronic diagnosis does not automatically make someone eligible for every C-SNP.

Examples of condition areas served by some C-SNPs can include diabetes, chronic heart failure, certain cardiovascular disorders, end-stage renal disease, cancer, HIV/AIDS, chronic lung disorders, or certain neurological and mental health conditions. This is not a promise that a 2027 plan serving your area covers a particular condition. The plan's approved eligibility criteria control.

Eligibility and confirmation

A C-SNP generally must confirm that you meet its condition requirement. The process may involve information from a clinician or medical record, and the plan should explain what documentation is needed and by when. Ask what happens if confirmation is delayed or unavailable. Never stop treatment or change doctors solely to qualify for a plan.

After eligibility, evaluate whether the plan's care model actually fits your day-to-day treatment. Look at specialist access, referral requirements, preferred pharmacies, prior authorization, medical equipment suppliers, infusion or dialysis arrangements when applicable, and the formulary rules for every prescription. Condition-focused care coordination can be useful, but it does not override network or coverage rules.

3. I-SNP: for an institutional level of care

An Institutional Special Needs Plan serves people who have had, or are expected to need, an institutional level of care for 90 days or longer. Qualifying settings can include certain long-term-care nursing facilities and other institutional settings recognized under Medicare rules. A plan may serve only selected facilities within its geographic service area.

Some people living in the community may qualify for an institutional-equivalent SNP when an approved assessment shows that they need the same level of care provided in an institution. This is sometimes called an I-SNP serving institutional-equivalent individuals. Living at home by itself does not establish eligibility, and needing help with a few daily activities is not necessarily the same as meeting the required level-of-care standard.

Questions for the facility, plan, and family

  • Does the plan contract with and actively serve the current facility or care setting?
  • Who completes the level-of-care assessment and how is the 90-day requirement documented?
  • Which clinicians provide routine and urgent care on site, and can established specialists remain involved?
  • How are hospital transfers, rehabilitation, pharmacy services, and care transitions coordinated?
  • What happens to eligibility and coverage if the person moves, improves, or changes facilities?

Families should compare more than the plan's extra benefits. The strongest practical fit often depends on how the plan works with the facility's nurses, physicians, pharmacy, and discharge team. Ask both the plan and facility to confirm their relationship for the 2027 plan year.

What all Medicare SNPs have in common

Although eligibility differs, D-SNPs, C-SNPs, and I-SNPs share several Medicare Advantage features. A person generally must be enrolled in Medicare Part A and Part B, live in the plan's service area, and continue meeting the special eligibility condition. SNPs must include Medicare Part D prescription drug coverage.

Coordinated care

SNPs use a model of care intended for their enrolled population. The exact care-team services, outreach, and condition management vary by plan.

Plan rules still apply

A plan may be an HMO, PPO, or another permitted Medicare Advantage structure. Network, referral, and prior-authorization rules depend on the contract.

Eligibility is ongoing

You must continue to meet the plan's special criteria. If eligibility changes, the plan should notify you of available time to change coverage.

Emergency care, urgently needed care outside the service area, and out-of-area dialysis have Medicare protections, but routine nonemergency out-of-network coverage depends on the plan type and rules. Confirm before receiving nonurgent care. Also remember that you normally continue paying the Medicare Part B premium even if a plan advertises a $0 plan premium, unless another program pays it for you.

Compare total costs, coverage, and access

Eligibility tells you which SNPs you may join. It does not tell you which one best fits your budget and care. Avoid selecting a plan from one headline benefit. Build a full-year picture that includes regular appointments, likely procedures, prescriptions, equipment, and travel to network providers.

What to check in each 2027 plan document
AreaVerifyWhy it matters
PremiumsPlan premium, Part B premium, and any Part D-related amountA $0 plan premium does not mean health care is free.
Medical costsDeductibles, copays, coinsurance, and annual in-network maximum out-of-pocket limitFrequent services can matter more than the monthly premium.
Medicaid coordinationWho pays Medicare cost-sharing and which services remain under MedicaidD-SNP members can have different Medicaid benefit levels.
PrescriptionsFormulary tier, pharmacy network, quantity limits, step therapy, and prior authorizationAll SNPs include Part D, but drug coverage is not identical.
ProvidersDoctor, hospital, facility, lab, pharmacy, and supplier participationDirectory listings can change; confirm with both provider and plan.
Extra benefitsEligibility, frequency, dollar limits, vendors, covered items, and unused-balance rulesAdvertisements may summarize restrictions that appear in plan documents.

For an accurate comparison, use the 2027 Summary of Benefits and Evidence of Coverage, not a prior-year brochure. Call the plan to verify uncertain details and record the representative's name, date, and reference number. Provider directories are helpful, but the provider and plan should both confirm network status for the exact plan name and year.

When can you enroll or switch for 2027?

Medicare Open Enrollment runs from October 15 through December 7, 2026, for coverage beginning January 1, 2027. During this period, eligible Medicare beneficiaries can make permitted Medicare Advantage and Part D changes. The Medicare Advantage Open Enrollment Period, January 1 through March 31, allows certain people already in Medicare Advantage to make one permitted change; it is not a general enrollment period for everyone with Original Medicare.

Special Enrollment Periods may allow changes at other times. The timing and available choices depend on the event—for example, gaining or losing Medicaid, qualifying for Extra Help, moving, entering or leaving an institution, or becoming eligible for an SNP. Some people with Medicaid or Extra Help have additional opportunities to change coverage, but the exact option is not identical in every circumstance.

Do not cancel existing coverage first. Confirm that the new plan has accepted the enrollment, note the effective date, and understand how any Medicaid or employer coverage will interact. If you receive an eligibility-loss notice, act by the deadline printed on it.

Information to gather before a plan review

  • Medicare card and, for a D-SNP review, current Medicaid information.
  • Home address and county, because availability is service-area specific.
  • Complete prescription list with dose, quantity, and preferred pharmacy.
  • Doctors, hospitals, care facilities, laboratories, and medical-equipment suppliers.
  • For a C-SNP, information about the qualifying condition and treating clinician.
  • For an I-SNP, facility details or documentation related to the level-of-care assessment.
  • Priorities such as specialist access, transportation, dental care, hearing services, or caregiver coordination.

Frequently asked questions

Do all Special Needs Plans include prescription drug coverage?

Yes. Medicare requires SNPs to include Medicare Part D prescription drug coverage. Formularies, pharmacy networks, tiers, and utilization rules still vary, so check every medicine in the specific 2027 plan.

Can I join a C-SNP just because I have a chronic condition?

Not necessarily. You must have a condition covered by that plan's approved eligibility criteria, satisfy its confirmation process, have Part A and Part B, and live in its service area. Different C-SNPs can serve different conditions.

Is a D-SNP the same as Medicaid managed care?

No. A D-SNP is a Medicare Advantage plan for people who also have Medicaid. Medicaid benefits remain governed by the state, though some D-SNPs integrate administration and care more closely with a Medicaid plan.

Can I change SNPs during the year?

Possibly. A Special Enrollment Period may apply based on Medicaid or Extra Help status, a move, institutional residence, a qualifying condition, or another event. The available change and deadline depend on the circumstance; confirm your specific window before submitting an enrollment.

What happens if I lose the eligibility that allowed me to join?

The plan should notify you and explain any period during which you may remain enrolled and your opportunity to choose other coverage. Deadlines matter. Contact the plan or Medicare promptly rather than waiting for coverage to end.

Is an I-SNP only for someone living in a nursing home?

No. Some I-SNPs serve people in other qualifying institutions, and some serve people living in the community who have been assessed as needing an institutional level of care. The plan's assessment, service area, and eligibility rules determine whether a person qualifies.
