Georgia Medicare C-SNP and I-SNP: How Chronic Condition and Institutional Special Needs Plans Work Under Section 1859 of the Social Security Act and Whether One Is Right for You

By Brevy Care Team · Last verified May 13, 2026

Medicare Special Needs Plans (SNPs) are a specialized category of Medicare Advantage plan authorized under Section 1859 of the Social Security Act (42 USC 1395w-28) and made permanent by the Bipartisan Budget Act of 2018. Unlike standard Medicare Advantage plans, SNPs restrict enrollment to one of three defined populations: dually eligible beneficiaries (D-SNPs), beneficiaries with specific severe or disabling chronic conditions (C-SNPs), or beneficiaries who reside in long-term care facilities or otherwise require an institutional level of care (I-SNPs and Institutional-Equivalent SNPs). Each SNP type must operate under a CMS-approved Model of Care that mandates specialized provider networks, an initial Health Risk Assessment within 90 days of enrollment with annual reassessment, an Individualized Care Plan, an Interdisciplinary Care Team, and detailed care transitions protocols. C-SNPs are limited to beneficiaries with one or more of 15 CMS-defined severe or disabling chronic conditions (diabetes, chronic heart failure, end-stage renal disease, cancer, dementia, and others). I-SNPs are limited to beneficiaries continuously residing in a qualifying long-term care facility, or living in the community while requiring an institutional level of care. For Georgia, where the C-SNP market focuses primarily on diabetes and cardiovascular care and the I-SNP market serves a smaller but critical population of nursing facility residents, these specialized plans offer condition-tailored care management and supplemental benefits that standard MA does not provide. This guide explains the federal framework, the 15 C-SNP qualifying conditions, the Model of Care requirement, enrollment periods, and how Georgia beneficiaries with specific chronic conditions or long-term institutional needs can use these plans. :::

Federal authority: Section 1859, 42 CFR 422.101(f), and the SNP framework

The Medicare Special Needs Plan framework rests on Section 1859 of the Social Security Act, codified at 42 USC 1395w-28. Section 1859 was created by the Medicare Prescription Drug, Improvement, and Modernization Act of 2003 to allow Medicare Advantage organizations to offer specialized plans restricted to defined populations. SNPs were originally authorized as a temporary demonstration. Congress extended SNP authority through the Medicare Improvements for Patients and Providers Act of 2008 and the Affordable Care Act of 2010, and finally made SNPs permanent through the Bipartisan Budget Act of 2018.

Section 1859(b)(6) of the Social Security Act defines three categories of "special needs individuals" who may be served by SNPs:

1. Dually eligible individuals (D-SNPs): Beneficiaries who are entitled to Medicare and also eligible for Medicaid. D-SNPs are covered in a separate Brevy guide.
2. Individuals with severe or disabling chronic conditions (C-SNPs): Beneficiaries with one or more chronic conditions defined by the Secretary of Health and Human Services.
3. Institutionalized individuals (I-SNPs and I-E-SNPs): Beneficiaries who continuously reside in a long-term care facility, or who reside in the community while requiring an institutional level of care.

Section 1859(f)(5) requires every SNP to have a CMS-approved Model of Care. The Model of Care is the detailed operational plan describing how the SNP will identify, assess, manage, and coordinate care for its specialized enrollee population. CMS regulations at 42 CFR 422.101(f) operationalize the Model of Care requirement through: (1) Health Risk Assessment, (2) annual reassessment, (3) Individualized Care Plan, (4) Interdisciplinary Care Team, (5) Care Transitions Protocols, (6) Provider Network qualifications, (7) Performance and Quality Improvement, and (8) Communication. The Model of Care is scored by the National Committee for Quality Assurance using a 13-element rubric; the resulting score determines whether the plan receives a 1-year, 2-year, or 3-year Model of Care approval.

For Georgia, the practical effect of this framework is that C-SNPs and I-SNPs offer significantly more intensive care management than standard Medicare Advantage plans, with specialized provider networks aligned to the enrolled population's needs and condition-specific supplemental benefits (e.g., glucometers for diabetes C-SNPs, dialysis transportation for ESRD C-SNPs, in-facility nurse practitioner visits for I-SNPs).

Chronic Condition Special Needs Plans (C-SNPs)

C-SNPs are Medicare Advantage plans restricted to beneficiaries with one or more of 15 CMS-defined severe or disabling chronic conditions. The C-SNP model is designed around condition-specific care management: networks include specialists relevant to the condition, supplemental benefits are tailored to condition needs, and Model of Care interventions focus on managing the condition and preventing complications.

The 15 qualifying conditions

CMS has defined 15 severe or disabling chronic conditions through regulation. As of plan year 2026, the qualifying conditions are:

1. Chronic alcohol and other drug dependence (substance use disorder)
2. Autoimmune disorders (limited to a defined subset of autoimmune conditions)
3. Cancer
4. Cardiovascular disorders
5. Chronic heart failure
6. Dementia
7. Diabetes mellitus
8. End-stage liver disease
9. End-stage renal disease (ESRD) requiring any mode of dialysis
10. Severe hematologic disorders
11. HIV/AIDS
12. Chronic lung disorders
13. Chronic and disabling mental health conditions
14. Neurologic disorders
15. Stroke

A given C-SNP may target a single condition (a "single-condition" C-SNP, like a Diabetes C-SNP), a combination of two or three related conditions (a "multi-condition" C-SNP, like a Diabetes-plus-Cardiovascular C-SNP), or a broader group of related conditions. In Georgia, the most common configurations are diabetes-only C-SNPs, diabetes-plus-cardiovascular C-SNPs, chronic heart failure C-SNPs, and ESRD C-SNPs.

Eligibility verification

Under 42 CFR 422.50(a)(4), each C-SNP enrollee must have the qualifying condition documented and verified by the plan. The plan may verify the condition through:

1. Physician attestation: A signed form from the enrollee's primary care provider or specialist confirming the qualifying diagnosis.
2. Medical records review: The plan obtains and reviews the enrollee's medical records.
3. Claims history review: The plan reviews the enrollee's Medicare claims history for evidence of the qualifying condition over the prior 12 to 24 months.

Verification must typically be completed within a set timeframe after enrollment. If the condition cannot be verified within that initial window, CMS allows a grace period for additional verification. If the condition still cannot be confirmed by the end of the grace period, the plan may involuntarily disenroll the beneficiary under 42 CFR 422.74(b).

In practice, most enrollments are verified through claims history within the first 30 days. Verification challenges arise primarily for beneficiaries new to Medicare (no prior claims), beneficiaries whose qualifying condition is borderline (e.g., pre-diabetes vs. diabetes), or beneficiaries whose qualifying condition has not been recently documented in clinical records.

Network and care management

C-SNPs must contract with providers qualified to serve the target population. The provider network includes:

• C-SNP for Diabetes: endocrinologists, certified diabetes educators (CDEs), podiatrists, ophthalmologists, registered dietitians
• C-SNP for Cardiovascular Disorders: cardiologists, cardiac rehab providers, vascular surgeons
• C-SNP for ESRD: nephrologists, dialysis facilities (Davita, Fresenius, etc.), transplant centers
• C-SNP for Chronic Lung Disorders: pulmonologists, respiratory therapists, pulmonary rehabilitation programs
• C-SNP for Cancer: oncologists, hematologists, radiation oncologists

Care management includes a Health Risk Assessment within 90 days of enrollment, an Individualized Care Plan, regular Interdisciplinary Care Team meetings, and condition-specific interventions (disease education, self-management support, medication adherence programs, transitions of care).

Condition-specific supplemental benefits

C-SNPs often offer supplemental benefits tailored to the qualifying condition. Examples:

• Diabetes C-SNP: glucose monitor supplies, continuous glucose monitor coverage, diabetic shoes, podiatry visits, dietitian consultations, A1C testing, diabetes education classes, healthy food allowances
• Cardiovascular C-SNP: cardiac rehab, home blood pressure monitors, weight scales, telemonitoring
• ESRD C-SNP: dialysis transportation (often three times per week), renal-friendly meal benefit, ESRD-specific medication adherence
• Chronic Lung Disorders C-SNP: pulmonary rehab, nebulizer maintenance, smoking cessation support
• Heart Failure C-SNP: remote heart failure monitoring (daily weight and symptoms via app), sodium-restricted meal benefit

Institutional Special Needs Plans (I-SNPs)

I-SNPs are Medicare Advantage plans restricted to beneficiaries who reside in long-term care facilities or who otherwise require an institutional level of care. I-SNPs operate under an intensive on-site care model: nurse practitioners and physicians visit the nursing facility regularly, the Interdisciplinary Care Team coordinates with facility staff, and the model is specifically designed to reduce unnecessary hospitalizations and ED visits.

I-SNP eligibility

Under Section 1859(b)(6)(A)(i) and 42 CFR 422.2, I-SNPs serve beneficiaries who meet one of two eligibility pathways:

1. Institutional pathway: The beneficiary continuously resides (or is expected to reside continuously) in a long-term care facility. Qualifying facilities include nursing facilities, intermediate care facilities for individuals with intellectual disabilities (ICF/IID), and certain assisted living facilities that meet state nursing facility level of care criteria. Eligibility is verified through facility admission records.

2. Institutional-equivalent pathway (I-E-SNP): The beneficiary resides in the community but requires an institutional level of care, determined by a state-approved assessment. In Georgia, the Comprehensive Pre-Admission Screening (CPAS) is the state's institutional level of care assessment. Some beneficiaries who would otherwise be eligible for nursing facility care receive home-based care funded through Medicaid waivers; an I-E-SNP can serve this population.

Care delivery model

I-SNPs differ from standard Medicare Advantage in care delivery:

• On-site clinical care: Most I-SNPs deploy nurse practitioners or physician assistants who conduct weekly or bi-weekly visits to the nursing facility, see members in their rooms, and provide on-site medical management.
• Hospital admission prevention: A primary I-SNP focus is reducing acute hospitalizations through proactive on-site care.
• Care Transitions: When an I-SNP member is hospitalized, the ICT receives immediate notification and coordinates discharge planning.
• Integration with facility staff: I-SNPs maintain close working relationships with nursing facility medical directors, directors of nursing, and social workers.

I-SNP supplemental benefits

I-SNPs typically offer benefits relevant to nursing facility populations:

• Comprehensive dental, vision, and hearing benefits
• Mobility aids (wheelchairs, walkers)
• Transportation (medical and non-medical)
• Coverage for facility-provided services that fall outside the Medicare benefit (e.g., personal care items, podiatry, mental health counseling)
• Caregiver support resources for families

The Model of Care: the heart of SNP regulation

Every SNP must operate under a CMS-approved Model of Care under Section 1859(f)(5) and 42 CFR 422.101(f). The Model of Care is the operational blueprint describing how the plan identifies, assesses, manages, and coordinates care for its specialized population. It is scored by the National Committee for Quality Assurance using a 13-element rubric; scores determine whether the plan receives a 1-, 2-, or 3-year Model of Care approval.

Element 1: Health Risk Assessment (HRA)

Within 90 days of enrollment, each SNP member must receive an initial Health Risk Assessment. The HRA covers:

• Medical history and current diagnoses
• Functional and cognitive status (often using validated tools like the SF-12 or PHQ-9 for depression screening)
• Psychosocial status (depression, isolation, abuse risk)
• Caregiver and support systems
• Health behaviors (nutrition, exercise, substance use)
• Preventive care needs
• Member preferences and goals for care

The HRA is typically conducted by telephone, video, or in-home visit by a nurse care manager.

Element 2: Annual Reassessment

The HRA must be repeated at least annually. Significant changes (hospitalization, new diagnosis, functional decline, change in living arrangement) trigger an interim reassessment.

Element 3: Individualized Care Plan (ICP)

Based on the HRA, the SNP develops an Individualized Care Plan that includes:

• Member's health goals
• Specific interventions to address identified needs
• Care coordination plan
• Provider assignments
• Self-management support
• Caregiver involvement

The ICP is communicated to the member, the primary care provider, and the Interdisciplinary Care Team.

Element 4: Interdisciplinary Care Team (ICT)

Each SNP member has an ICT consisting at minimum of:

• The member's Primary Care Provider
• A Nurse Care Manager
• A Social Worker or behavioral health professional
• The member (and family or caregiver if appropriate)

The ICT meets at defined intervals (typically quarterly for stable members, more frequently for members with significant care needs) to review the ICP, coordinate care across providers, and adjust interventions.

Element 5: Care Transitions Protocols

SNPs must have detailed protocols for managing care transitions:

• Hospital admission: ICT notification within 24 hours. Care manager contacts the hospital case manager.
• Hospital discharge: Transition assessment within 24 to 72 hours of discharge. Medication reconciliation. Follow-up appointment scheduling.
• SNF or rehabilitation transition: Coordination with the receiving facility.
• Emergency Department visits: ICT outreach within 24 hours.

Element 6: Provider Network Qualifications

The SNP must contract with providers qualified to serve the target population. CMS scrutinizes the network for adequate specialty coverage relevant to the condition or institutional setting.

Element 7: Performance and Quality Improvement

SNPs report SNP-specific HEDIS measures, including:

• SNP Care for Older Adults: Medication Review: Did the plan conduct a medication review for members aged 66+ in the past year?
• SNP Care for Older Adults: Functional Status Assessment: Did the plan conduct a functional status assessment?
• SNP Care for Older Adults: Pain Assessment: Did the plan conduct a pain assessment?
• SNP Care for Older Adults: Advance Care Planning: Did the plan discuss advance care planning?

These measures feed into the SNP's overall Medicare Star Rating.

Element 8: Communication

The Model of Care must be communicated to enrollees in plain language and to providers through training. Plans publish the Model of Care document publicly.

SNP enrollment periods

Initial Coverage Election Period (ICEP)

Same as for any Medicare Advantage plan: the 7-month period beginning 3 months before the month of Medicare entitlement and ending 3 months after.

Annual Enrollment Period (AEP)

October 15 through December 7 each year. Beneficiaries may enroll in or switch SNPs (subject to eligibility verification). Effective date January 1.

Special Enrollment Periods for SNPs

Several SEPs are particularly relevant for SNPs:

• 42 CFR 422.62(b)(3): SEP for newly diagnosed chronic condition. A beneficiary newly diagnosed with one of the 15 C-SNP qualifying conditions may enroll in a C-SNP outside AEP.
• 42 CFR 422.62(b)(5): SEP for changes related to long-term care facility status. Triggers I-SNP eligibility upon facility admission or termination of I-SNP eligibility upon facility discharge.
• 42 CFR 422.62(b)(2): SEP for change in residence affecting plan availability.
• 42 CFR 422.62(b)(4): SEP for involuntary plan termination.

Medicare Advantage Open Enrollment Period (MA OEP)

January 1 through March 31. MA enrollees may make a one-time change to another MA plan or to Original Medicare. SNP enrollees may use this to switch to a different plan if they remain eligible.

C-SNP and I-SNP compared to standard Medicare Advantage

C-SNPs and I-SNPs differ from standard Medicare Advantage in several important ways.

::: table caption="C-SNP and I-SNP compared to standard Medicare Advantage"

Combined SNP types: when a plan is both D-SNP and C-SNP

Some plans operate as combined Dual-Eligible Chronic Condition SNPs (D-C-SNPs), serving beneficiaries who are both dually eligible AND have a qualifying chronic condition. These plans must meet both:

1. D-SNP coordination requirements under 42 CFR 422.107 (Medicaid coordination, LTSS access for HIDE and FIDE SNPs, integrated member communications)
2. C-SNP care management requirements under the Model of Care

In Georgia, several major plans operate D-C-SNP variants for diabetes and cardiovascular conditions, including Humana, BCBS GA, and Wellcare. For dually eligible Georgians with qualifying chronic conditions, a D-C-SNP can offer the integration benefits of a D-SNP plus the condition-specific Model of Care benefits of a C-SNP.

For comparison: Brevy's separate guide on D-SNPs covers HIDE (Highly Integrated Dual Eligible) and FIDE (Fully Integrated Dual Eligible) SNPs, which provide the strongest Medicaid integration but do not always include C-SNP-style chronic condition focus.

Worked examples for Georgia

Example 1: Margaret 67 Atlanta diabetes C-SNP

Margaret has Type 2 diabetes diagnosed in 2018. She takes metformin, semaglutide (Ozempic), and basal insulin. During AEP for plan year 2026, she enrolls in Humana C-SNP for Diabetes with a January 1, 2026 effective date.

Verification: Within 21 days of enrollment, Humana verifies Margaret's diabetes diagnosis through Medicare claims history (multiple endocrinology visits, A1C tests, glucose monitor supplies).

HRA: A Humana nurse care manager calls Margaret in February 2026 to conduct the initial Health Risk Assessment. The HRA covers diabetes status (HbA1c 9.2 percent at last lab), medication review, neuropathy screening, eye exam history (overdue), foot exam status (overdue), social determinants, and goals.

ICP: Based on the HRA, Margaret's Individualized Care Plan includes:

• Endocrinology referral within 30 days
• Comprehensive diabetes self-management education (DSME)
• Annual ophthalmology eye exam scheduled
• Podiatry referral for diabetic foot exam
• Glucometer supplies via mail-order (no cost)
• $50 per quarter healthy food allowance

ICT: Margaret's Interdisciplinary Care Team consists of her PCP, the Humana nurse care manager, a registered dietitian, and Margaret. They meet quarterly by phone.

Outcome: By December 2026, Margaret's HbA1c has dropped to 7.4 percent. Her annual reassessment in 2027 confirms continued diabetes management focus.

Example 2: Robert 70 Savannah cardiovascular C-SNP

Robert has chronic heart failure (LVEF 35 percent, NYHA Class II) and atrial fibrillation. He enrolls in Wellcare C-SNP for Chronic Heart Failure effective March 1, 2026 (within his Initial Coverage Election Period as he turned 65 in February 2026).

Verification: Wellcare verifies the heart failure diagnosis through claims (cardiology visits, echocardiogram, ACE inhibitor and beta-blocker prescriptions).

HRA: Wellcare's care manager performs the HRA in April 2026, identifying high hospitalization risk based on NYHA class and recent ED visits.

ICP: Robert's care plan includes:

• Cardiology specialist assignment with monthly visits initially
• Remote heart failure monitoring program (daily weight and symptom tracking via mobile app)
• Medication adherence program with weekly pillbox check-ins
• Transportation benefit for cardiac rehab (covered three times per week)
• Sodium-restricted meal benefit ($150 per month)
• Care Transitions protocol triggering immediate outreach for any ED or hospital visit

ICT: Robert's ICT includes his PCP, his cardiologist, a Wellcare nurse care manager, and Robert.

Outcome: In June 2026, Robert is admitted for an HF exacerbation. Within 24 hours, the hospital admission triggers Wellcare ICT notification. Within 48 hours of discharge, a transition assessment is conducted; his diuretic regimen is adjusted, and follow-up cardiology and PCP appointments are scheduled within 7 days. Robert does not readmit within 30 days. Without the C-SNP Care Transitions protocol, a 30-day readmission was statistically likely.

Example 3: Linda 68 Macon ESRD C-SNP

Linda has end-stage renal disease and started peritoneal dialysis in October 2025. ESRD beneficiaries can now enroll in Medicare Advantage plans. Linda enrolls in an ESRD-focused C-SNP effective May 1, 2026.

Verification: ESRD is verified through Medicare claims showing dialysis services.

HRA: The C-SNP's nurse care manager conducts the HRA in-home given Linda's dialysis schedule. The HRA covers dialysis adequacy, anemia management, phosphate control, vascular access status, transplant evaluation status, and social supports.

ICP: Linda's care plan is tailored to ESRD:

• Nephrology specialist assignment
• Coordination with the Davita Macon dialysis center
• Transportation benefit specifically for dialysis (three times per week, covered)
• Renal-friendly meal benefit
• Medication adherence focus (phosphate binders, ESA injections, antihypertensives)
• Transplant evaluation referral coordination

ICT: Linda's ICT includes her PCP, her nephrologist, the dialysis center social worker, the dialysis facility nurse manager, and Linda.

Outcome: Linda's dialysis adherence improves due to reliable transportation. Her serum phosphate stabilizes due to medication adherence support. She is referred for transplant evaluation in October 2026.

Example 4: Charles 78 Augusta I-SNP nursing facility

Charles is a long-stay resident of an Augusta nursing facility. He has dementia, diabetes, and chronic heart failure. He has resided in the facility for 14 months. He is enrolled in AllyAlign Health I-SNP effective February 1, 2026, by his daughter (durable power of attorney for healthcare).

Verification: Facility admission records confirm Charles's eligibility based on continuous nursing facility residence.

HRA: The AllyAlign nurse practitioner conducts the HRA at the facility in February 2026. The HRA covers Charles's three chronic conditions, functional status, cognitive status (MMSE), pain assessment, advance care planning, and goals of care (Charles, with his daughter's input, has chosen DNR/DNI status).

ICP: Charles's care plan focuses on:

• Aggressive on-site medical management to prevent hospital admissions
• Bi-weekly NP visits in the facility
• Coordination with the facility medical director
• Diabetes management with simplified medication regimen (avoiding hypoglycemia risk)
• Heart failure monitoring (daily weight by facility staff)
• Comfort-focused care reflecting goals
• Family communication plan (daughter receives weekly updates)

ICT: Charles's ICT includes the facility medical director, the AllyAlign NP, the facility director of nursing, the AllyAlign social worker, the AllyAlign RN care manager, and Charles's daughter.

Outcome: Before I-SNP enrollment, Charles had 4 hospitalizations in 2025. In 2026 (his first year with the I-SNP), he has 1 hospitalization. The intensive on-site care, supported by aggressive ICT coordination, dramatically reduces unnecessary acute care utilization.

Example 5: Patricia 72 Columbus C-SNP qualifying condition verification

Patricia has chronic obstructive pulmonary disease (COPD) diagnosed in 2022, with FEV1 of 55 percent of predicted, requiring inhaled corticosteroid-LABA combination therapy. She enrolls in a chronic lung disorders C-SNP for plan year 2026, with a January 1, 2026 effective date.

Verification process: The plan reviews Patricia's Medicare claims history for the prior 24 months. Documented COPD-related claims include:

• Annual spirometry
• Pulmonologist visits (every 6 months)
• Inhaled corticosteroid-LABA prescriptions filled monthly
• One pulmonary rehab episode in 2024

Verification is complete within 21 days.

If verification had failed: If claims history did not adequately document COPD, the plan would have requested a physician attestation form from Patricia's PCP or pulmonologist. If still unverifiable, Patricia would have entered a grace period during which the plan could request medical records. Failure to verify by the end of the grace period would trigger involuntary disenrollment under 42 CFR 422.74(b), with Patricia receiving a Special Enrollment Period to enroll in a different MA plan or return to Original Medicare.

Care management: Once verified, Patricia begins receiving the chronic lung disorders C-SNP's Model of Care: pulmonary rehabilitation (covered), inhaler technique coaching, smoking cessation support (she stopped smoking in 2019 but receives ongoing relapse prevention), home nebulizer maintenance, and respiratory therapist consultations.

Example 6: Henry 75 Athens dual C-SNP / D-SNP comparison

Henry is dually eligible for Medicare and Medicaid (full QMB Plus) and has Type 2 diabetes. He is comparing three options for plan year 2026:

Option A: Standalone Humana C-SNP for Diabetes. Targets diabetes-specific care management; coordinates with Medicaid for cost-sharing but does not provide full Medicaid integration.

Option B: Anthem BCBS GA HIDE D-SNP (Highly Integrated Dual Eligible Special Needs Plan). Targets dually eligible beneficiaries with integrated Medicare and Medicaid benefits including LTSS coordination, $0 cost-sharing, integrated member ID card, and Medicaid behavioral health coordination. Does not include condition-specific Model of Care.

Option C: A combined D-SNP + C-SNP for Diabetes (where available in his county). Provides full D-SNP integration plus diabetes Model of Care.

After GeorgiaCares SHIP counseling, Henry reviews the trade-offs:

• Option A provides better diabetes management but less Medicaid integration
• Option B provides the strongest Medicaid integration (HIDE-level) but generic care management
• Option C provides both if available

Henry confirms that Option C is available in Athens (Clarke County). He enrolls in the combined D-SNP/C-SNP effective January 1, 2026. This gives him integrated Medicare and Medicaid benefits AND condition-specific diabetes care management.

Common mistakes to avoid

1. Enrolling in a C-SNP without confirming you have a qualifying condition documented. The 15 conditions are specific and may not include conditions you assume qualify (e.g., hypertension alone does not qualify; cardiovascular disorders is a defined category).

2. Believing C-SNP availability is universal across Georgia. C-SNPs vary significantly by county. A diabetes C-SNP available in Atlanta may not be available in Athens.

3. Confusing C-SNP with standard Medicare Advantage chronic care management. Standard MA may offer disease management programs, but only a C-SNP operates under a CMS-approved Model of Care with mandatory HRA, ICP, and ICT.

4. Missing the SEP triggered by a new chronic condition diagnosis. Under 42 CFR 422.62(b)(3), a newly diagnosed qualifying condition opens a Special Enrollment Period to enroll in a C-SNP.

5. Failing to complete the initial Health Risk Assessment. The HRA must be completed within 90 days of enrollment. Failure can affect the plan's ability to develop your Individualized Care Plan.

6. Misunderstanding I-SNP eligibility. I-SNPs require qualifying continuous LTC facility residence OR institutional-equivalent need. They are not available to occasional facility residents (e.g., short-term rehab patients).

7. Believing I-SNPs are only available in nursing facilities. Institutional-Equivalent SNPs (I-E-SNPs) serve community-dwelling beneficiaries who require an institutional level of care.

8. Choosing a single-condition C-SNP without considering multi-condition options. If you have diabetes plus cardiovascular disease, a multi-condition C-SNP may better address your full care needs.

9. Not coordinating with Medicaid for dual-eligible C-SNP enrollees. Dually eligible beneficiaries should consider whether a combined D-SNP/C-SNP is available and would better serve their needs.

10. Missing the annual Health Risk Assessment reassessment. The HRA must be repeated annually. Plans typically reach out, but if you miss outreach, contact the plan to ensure the reassessment is completed.

11. Believing C-SNP/I-SNP enrollment continues if eligibility lapses. If your qualifying condition cannot be re-verified (rare) or if you leave the qualifying facility (for I-SNPs), the plan may involuntarily disenroll you.

12. Not using the ICT structure to coordinate care across specialists. The Interdisciplinary Care Team is a powerful tool for ensuring consistent care across multiple providers. Engage with it.

13. Confusing the SNP's Model of Care with general MA care management. The Model of Care is a CMS-approved, NCQA-scored framework that goes well beyond what standard MA plans typically offer.

Frequently asked questions

::: accordion

What is the legal authority for Medicare Special Needs Plans?

Special Needs Plans are authorized under Section 1859 of the Social Security Act (42 USC 1395w-28). Originally created under the Medicare Prescription Drug, Improvement, and Modernization Act of 2003 as a temporary demonstration, SNPs were made permanent by the Bipartisan Budget Act of 2018. Implementing regulations sit at 42 CFR Part 422 Subpart B and 42 CFR 422.101(f) (Model of Care).

What are the 15 C-SNP qualifying conditions?

CMS has defined 15 qualifying conditions: chronic alcohol and drug dependence; autoimmune disorders (defined subset); cancer; cardiovascular disorders; chronic heart failure; dementia; diabetes mellitus; end-stage liver disease; end-stage renal disease; severe hematologic disorders; HIV/AIDS; chronic lung disorders; chronic and disabling mental health conditions; neurologic disorders; and stroke.

How is C-SNP eligibility verified?

Under 42 CFR 422.50(a)(4), the plan must verify the qualifying condition through physician attestation, medical records review, or claims history. Verification must typically be completed within a set timeframe after enrollment, with a grace period available if additional time is needed. If the condition cannot be verified, the plan may involuntarily disenroll the beneficiary under 42 CFR 422.74(b).

Who can enroll in an I-SNP?

I-SNPs serve beneficiaries who continuously reside in a qualifying long-term care facility (nursing facility, ICF/IID, or qualifying assisted living), OR who reside in the community while requiring an institutional level of care (I-E-SNP). Eligibility is verified through facility admission records or a state-approved institutional level of care assessment.

Are there special enrollment periods for SNPs?

Yes. Under 42 CFR 422.62(b)(3), a beneficiary newly diagnosed with a C-SNP qualifying condition gets a Special Enrollment Period to enroll. Under 42 CFR 422.62(b)(5), entering or leaving a long-term care facility triggers an SEP for I-SNP eligibility changes. Other SEPs apply for changes in residence, plan terminations, and Medicare-Medicaid status changes. :::
