2027 Medicare Special Needs Plans Agent Guide

D-SNP, C-SNP and I-SNP eligibility, enrollment and practical plan reviews

Source review: October 7, 2026

Quick answer

A Dual Eligible Special Needs Plan (D-SNP) serves people whose Medicare and Medicaid eligibility meets that plan’s requirements. A Chronic Condition Special Needs Plan (C-SNP) serves people with the severe or disabling chronic conditions targeted by the plan. An Institutional Special Needs Plan (I-SNP) serves people who meet its institutional or institutional-equivalent criteria. All three are Medicare Advantage plans with Part D drug coverage. Medicare

For 2027, the most consequential new enrollment check is Medicaid plan alignment for affected D-SNPs. Certain applicants must be enrolled in, or in the process of enrolling in, the affiliated Medicaid managed care organization. Existing members and new applicants can face different rules. ecfr.gov

Before recommending any SNP, answer three separate questions:

1. Eligibility: Does the client meet the requirements of this exact plan?
2. Enrollment: Is there a valid election period for the requested change and effective date?
3. Fit: Will the plan support the client’s doctors, prescriptions, costs and ongoing care?

A favorable answer to one question does not settle the other two. An allowance, diagnosis or nursing-facility address should start a closer review.

Use our 2027 Medicare Advantage changes by county guide to identify local options. Then use this guide to decide which plans belong in the individual client’s comparison.

What agents need to update for 2027

These requirements come from the D-SNP alignment regulations, integrated assessment and ID-card rules, updated enrollment guidance, and SSBCI requirements. ecfr.gov

The current C-SNP condition framework and the monthly dual/LIS and integrated-care SEPs continue into 2027. They should not be presented as newly created 2027 benefits or enrollment rights. ecfr.gov

Compare the three SNP types

All applicants also need ordinary Medicare Advantage eligibility, including Medicare Parts A and B and residence in the plan’s service area. C-SNP and I-SNP eligibility does not, by itself, require Medicaid. A person may qualify for more than one SNP category; each option still needs its own review. CMS

SNPs may use HMO or PPO structures. Check the actual network and referral rules instead of assuming that a special-needs designation provides unrestricted provider access. ecfr.gov

Dual Eligible Special Needs Plans

Verify the Medicaid category

“I have Medicaid” is not enough information to complete a D-SNP review. The plan must accept the client’s specific category, and the state Medicaid contract may impose additional enrollment requirements. ecfr.gov

Use the following as a category reference, then obtain current verification through the carrier’s approved process.

This table describes categories, not a promise that every D-SNP accepts them. State rules and the client’s verified status determine Medicaid benefits and assistance. Extra Help alone does not establish Medicaid eligibility for a D-SNP. revised 2-11-2026

Avoid inserting a prior year’s income or resource limits into a 2027 screening sheet. Use the state Medicaid agency’s current eligibility information when helping a client seek assistance.

Explain QMB protection accurately

Clients with QMB Only or QMB Plus have federal protection against being billed for Medicare Part A and Part B deductibles, copayments and coinsurance for Medicare-covered services. This protection applies in Original Medicare and Medicare Advantage. It does not turn every prescription, noncovered service or supplemental benefit into a free benefit. CMS

If a QMB client reports a bill, help them identify the service and date, confirm QMB status, and contact the plan or provider billing office. A plan comparison should not treat prohibited QMB cost-sharing bills as legitimate expected expenses.

Make Medicaid alignment a 2027 enrollment check

The federal rule applies when a D-SNP organization, its parent or a related entity also holds a Medicaid MCO contract that enrolls full-benefit duals, and the relevant service areas overlap, even partly.

Starting in 2027, affected D-SNPs generally must limit new enrollment to people enrolled in, or in the process of enrolling in, that affiliated Medicaid MCO. The rule also generally limits the organization to one D-SNP for full-benefit duals in the affected area, subject to exceptions. ecfr.gov

For these plans, the corresponding restriction on continued coverage of existing members begins in 2030, subject to deemed continued eligibility. State requirements can apply sooner. An existing member should follow the actual renewal and transition notices; this federal phase-in does not require every current D-SNP member to change Medicaid plans in January 2027. cms.gov

The Medicaid fee-for-service exception matters. The 2027 final rule permits state-authorized additional D-SNPs for full-benefit duals receiving Medicaid fee-for-service where the state does not mandate managed care for every full-benefit dual. Those plans cannot enroll full-benefit duals in an unrelated organization’s Medicaid MCO. Other exceptions address specified state enrollment groupings and plan arrangements. ecfr.gov

Ask the carrier to confirm which rule applies to the exact 2027 plan benefit package. A carrier’s brand name, presence in the county or general statement that it serves duals does not establish the applicant’s eligibility.

For each D-SNP review, record:

• The client’s exact Medicaid category and verification source.
• The current Medicaid MCO, or confirmation that Medicaid is fee-for-service.
• Whether the proposed D-SNP requires an affiliated Medicaid enrollment.
• Any Medicaid change needed, its timing and who will complete it.
• The effect on home care, long-term services and supports, behavioral health, equipment and existing authorizations.

Example: Angela receives home-care services through Medicaid MCO A and is considering a D-SNP aligned with Medicaid MCO B. Before discussing an enrollment date, verify the Medicare election period, Medicaid change process, home-care agency participation and continuity arrangements. A larger advertised allowance does not answer those questions.

Understand the integration labels

Integration labels help identify how Medicare and Medicaid work together:

• HIDE SNP: A highly integrated D-SNP with specified Medicaid coverage for long-term services and supports, behavioral health, or both.
• FIDE SNP: A fully integrated D-SNP with broader Medicare–Medicaid integration and exclusively aligned enrollment.
• AIP: An Applicable Integrated Plan designation associated with integrated administration and appeals. It overlaps with certain D-SNP arrangements; it is not another basic SNP type.

The precise definitions and state contracts control. Do not assume every HIDE SNP is an AIP. ecfr.gov

For AIP D-SNPs, the integrated member ID card and single comprehensive Medicare–Medicaid assessment are required by 2027. Explain which card the member should present and how the plan will contact them. Other clinical assessments may still be appropriate. ecfr.gov

CMS’s D-SNP integration resource page includes a 2027 Integrated D-SNP list and state-specific materials. Use it alongside carrier and state guidance. CMS

Use the correct monthly enrollment pathway

The two monthly pathways have different purposes.

These rules took effect in 2025 and continue in 2027. The dual/LIS SEP does not authorize a monthly MA-PD-to-MA-PD switch. An MA-PD member using it to elect a standalone PDP generally returns to Original Medicare. The integrated-care SEP is limited to qualifying aligned enrollment. cms.gov

Other election periods may apply, including AEP, MA OEP or a separate SEP. Being eligible for a D-SNP and being allowed to enroll in that D-SNP this month remain separate questions.

A useful client explanation is:

Chronic Condition Special Needs Plans

Match the diagnosis to the exact plan

A C-SNP may focus on one qualifying condition or an approved grouping. The client’s condition must match that specific plan’s target population. Medicaid or Extra Help is not a prerequisite to C-SNP eligibility. Medicare

When the county comparison identifies additional C-SNP choices, revisit the client’s existing diagnosed conditions and treating providers. Use that information to identify plans worth comparing. New local availability does not establish that the client qualifies or would benefit from changing coverage.

Use the current 22 condition categories

The current regulation identifies these categories. The full definitions contain additional detail; this abbreviated reference does not replace the plan’s eligibility criteria. ecfr.gov

Agents should not use an older 15-category training sheet as the current complete list.

One condition can qualify within an approved grouping

CMS permits eight specified groupings:

1. Diabetes mellitus and chronic heart failure.
2. Chronic heart failure and cardiovascular disorders.
3. Diabetes mellitus and cardiovascular disorders.
4. Diabetes mellitus, chronic heart failure and cardiovascular disorders.
5. Stroke and cardiovascular disorders.
6. Anxiety associated with COPD.
7. Chronic kidney disease and care after kidney transplantation.
8. Substance use disorders and chronic mental health disorders. ecfr.gov

For a plan using an approved grouping, one qualifying condition in that grouping is sufficient. The applicant does not need every condition named. ecfr.gov

Example: Samuel has confirmed chronic heart failure but no diabetes. A plan approved for the diabetes, chronic heart failure and cardiovascular grouping may accept him through its verification process. Compare his cardiologist, hospitals, prescriptions and care-management needs before making a recommendation.

Track provider verification through completion

The plan must obtain confirmation from the applicant’s current qualifying physician, physician assistant or nurse practitioner. The agent gathers accurate information and follows up; the provider confirms the condition.

The plan can verify the condition before enrollment or use a pre-enrollment qualification assessment tool (PQAT) with subsequent provider confirmation.

These are continuing federal requirements. ecfr.gov

January 2027 example: For a January 1 effective date, first-month verification is due by January 31. If missing, the notice goes out February 1–7, with disenrollment scheduled for the end of February. Confirmation before February ends allows coverage to continue.

At intake, collect the exact reported diagnosis, treating provider’s name and current contact details. Track whether confirmation is pending, received or unsuccessful. A medication list or the client’s suspicion of a condition does not substitute for the required provider verification.

The chronic condition SEP has a specific limit

An eligible person can use the C-SNP SEP to enroll in a plan designed for their qualifying condition. Once enrolled, that use of the SEP ends.

A person already in a C-SNP may use this SEP for another qualifying condition that is not a focus of the current C-SNP. It does not provide repeated shopping among plans serving the same condition. ecfr.gov

Consider two examples:

• Current plan targets diabetes only: A client who also has qualifying chronic heart failure may be able to use this SEP for a C-SNP focused on heart failure.
• Current plan targets diabetes and heart failure: Heart failure is already a focus. That condition alone does not create this SEP for a move to another heart-failure C-SNP.

The second client may have AEP, MA OEP or another election period. Document the actual basis instead of selecting a C-SNP SEP solely because the destination is a C-SNP.

Institutional Special Needs Plans

Identify the institutional pathway

An FI-SNP must own or contract with the institutional facilities serving its members. A plan appearing in a county listing does not establish that it serves the client’s particular facility. ecfr.gov

For institutional residence, the standard is actual or expected continuous residence of at least 90 days in a qualifying setting. A documented expectation can support enrollment before the 90th day. A brief rehabilitation stay alone does not establish eligibility. CMS

Qualifying settings include specified nursing, intermediate-care and hospital settings. Confirm that the facility meets the federal definition through the carrier’s eligibility process.

Community eligibility requires a level of care determination

A client living at home or in assisted living may qualify for an IE-SNP if they meet the institutional level-of-care criteria. The required assessment uses the state’s tool or applicable methodology and must be completed by an impartial entity with the necessary expertise. CMS specifies that the plan cannot own or control the assessor. CMS

An assisted-living address, disability diagnosis, family caregiving arrangement or need for help with daily activities does not, by itself, complete this determination.

Ask who arranges the assessment, when it must be completed and how its result will be documented. Separately confirm the election period and whether the plan can provide its care model at the client’s residence.

Confirm the institutional election period separately

The Open Enrollment Period for Institutionalized Individuals (OEPI) uses the institutionalized definition, including the actual-or-expected 90-day standard. It continues through the qualifying stay and ends two months after the month the person leaves. Enrollment is generally effective on the first day of the month after the plan receives the request. cms.gov

Example: A qualifying resident leaves the facility on February 12, 2027. Their OEPI ends April 30, 2027. Whether the current I-SNP can continue covering them is a separate eligibility and care-delivery question.

Community institutional-equivalent status alone does not establish OEPI. Verify another applicable election period for an IE-SNP applicant. Also confirm that the receiving plan accepts OEPI enrollments; this period can support MA choices beyond I-SNPs. cms.gov

Compare access and costs before extra benefits

For every eligible option, compare the client’s current coverage with the proposed 2027 plan using current plan documents.

For Part D, the finalized 2027 maximum deductible is $700 and the annual out-of-pocket threshold is $2,400 for covered Part D drugs. Individual plan designs and Extra Help can change the client’s actual costs. Use our 2027 Part D changes and drug review guide for the complete prescription comparison. www.cms.gov

Verify eligibility for condition-based extra benefits

Some allowances are Special Supplemental Benefits for the Chronically Ill (SSBCI). C-SNP enrollment or a chronic diagnosis alone does not establish eligibility for every SSBCI.

For 2027, check the plan’s publicly posted eligibility policies and objective criteria. Then verify the specific benefit, the client’s eligibility determination, covered purchases, frequency, expiration and any access requirements. govinfo.gov

If a client may qualify for both a D-SNP and a C-SNP, compare the whole arrangement. Include Medicare providers, prescriptions, Medicaid coordination, cost protections and care needs. The advertised allowance should be evaluated within that comparison.

Prepare the member for the care team

All SNPs must implement a Model of Care for their target population. The plan’s assessment and follow-up help translate enrollment into usable care.

Federal requirements include an initial comprehensive health risk assessment within 90 days before or after the enrollment effective date, an annual assessment and an individualized care plan. The care plan is due within 90 days after the initial assessment or 90 days after the enrollment effective date, whichever is later.

The plan must make at least three nonautomated attempts on different days and at different times to schedule the assessment, unless the member accepts or declines sooner, and send a follow-up letter if there is no response. ecfr.gov

Help the member understand why the care team will contact them. Confirm preferred language, accessible communication needs, contact information and the authorized caregiver or representative. Encourage the member to describe medication access, food, housing, transportation and daily-care concerns accurately.

A useful handoff question is: “Who should you contact if you cannot get a prescription, your home-care arrangement changes or you leave the facility?”

Respond promptly when special-needs status changes

A Medicaid redetermination, institutional discharge or other status change should trigger a new eligibility review.

If the member can reasonably be expected to regain the qualifying status within six months, CMS’s 2027 guidance permits a plan-specific deemed-eligibility period of one to six months. The regulation describes at least 30 days and no more than six months. Confirm the plan’s disclosed policy; six months is not automatic.

The 2027 guidance clarifies that this period begins on the first of the month after the month the loss information is available to the plan and communicated to the member, including retroactive Medicaid terminations. cms.gov

Record the loss date, notification date, applicable continued-eligibility period and planned disenrollment date. For an I-SNP member leaving a facility, confirm whether the plan can continue delivering care at the new residence; the guidance identifies inability to provide continuity of care as a reason disenrollment may be required. cms.gov

Two enrollment situations must remain distinct:

• Later loss of SNP status: The loss-of-status SEP begins in the month status changes and ends when used or three calendar months after the effective date of involuntary SNP disenrollment, whichever comes first.
• C-SNP applicant found ineligible after enrollment: The corrective SEP begins with the plan’s notice and extends through that month and the following two calendar months, ending sooner if used. ecfr.gov

The general continued-eligibility period does not extend the C-SNP’s initial PQAT verification deadline. Work from the actual notices and coordinate replacement medical and drug coverage before the current coverage ends.

Frequently asked questions

Does Extra Help qualify someone for a D-SNP?

Extra Help alone is insufficient. The client must have Medicaid status accepted by that D-SNP and meet its other requirements. cms.gov

Does a C-SNP require every condition in its name?

For an approved multiple-condition grouping, one qualifying condition is sufficient. Verify the plan’s actual approved grouping and complete its confirmation process. ecfr.gov

Can a client switch between C-SNPs whenever they want?

The C-SNP SEP ends upon enrollment. For an existing C-SNP member, another use requires a qualifying condition outside the current plan’s focus. Otherwise, another valid election period is needed. ecfr.gov

Does assisted living automatically qualify someone for an I-SNP?

No. Confirm the exact plan and eligibility pathway. A community applicant generally needs the required institutional level-of-care assessment; the address alone is insufficient. CMS

Must every current D-SNP member align Medicaid in January 2027?

No. The federal 2027 restriction concerns new enrollment in affected plans. Its corresponding continued-coverage restriction begins in 2030, while state and plan requirements may apply sooner. Review the member’s actual notices. ecfr.gov

When is AEP for 2027 coverage?

The Annual Election Period runs October 15 through December 7, 2026, for coverage effective January 1, 2027. SNP eligibility must still be established even when AEP supplies the enrollment opportunity. www.medicare.gov

Put the evidence into the annual review

Keep eligibility evidence, plan-specific findings, election-period support and follow-up tasks together. The record should explain both why the client could enroll and why the selected coverage fits their needs.

Informed + Choice supports an organized annual review workflow. Use the county guide to identify options, this SNP guide to evaluate eligibility and care needs, and the Part D guide to complete the prescription comparison.
