D-SNP (Dual Eligible Special Needs Plan) Denied — Your Rights

If you have both Medicare and Medicaid, you are what's called a "dual eligible" beneficiary. You may be enrolled in a Dual Eligible Special Needs Plan — a type of Medicare Advantage plan specifically designed to serve people in your situation, integrating benefits from both programs into a single plan.

A D-SNP denial can be particularly complicated, because it may involve Medicare rules, Medicaid rules, or both. The good news is that dual eligibles have two sets of appeal rights — and knowing how to use both gives you powerful tools to fight denials.

What Is a D-SNP?

A Dual Eligible Special Needs Plan (D-SNP) is a Medicare Advantage plan that contracts with state Medicaid programs to serve beneficiaries enrolled in both Medicare and Medicaid. D-SNPs are required to:

• Cover all Medicare benefits
• Coordinate with Medicaid benefits
• Provide extra benefits targeted to dual eligibles' complex health needs
• Assign a care coordinator to each enrolled member

There are different types of D-SNPs depending on the level of Medicaid integration — from basic coordination-only plans to fully integrated plans where both Medicare and Medicaid benefits are managed together.

What D-SNPs Cover

A D-SNP covers everything Original Medicare covers, plus any additional D-SNP benefits your plan offers. Depending on your plan and state:

• Medicare Part A hospital and skilled nursing care
• Medicare Part B medical services and outpatient care
• Medicare Part D prescription drugs
• Medicaid benefits (which vary by state) such as long-term services and supports, personal care, transportation, dental, vision
• Extra supplemental benefits for dual eligibles, which may include meal delivery, home safety modifications, or chronic disease management programs

The exact combination of benefits depends on your plan and your state's Medicaid program.

Why D-SNP Claims Get Denied

Medicare benefit denied. The D-SNP denied a claim that falls under Medicare's standard coverage — such as an inpatient hospital stay, outpatient procedure, or specialist visit. These denials follow Medicare Advantage appeal rules.

Medicaid benefit denied. The plan denied a service that should be covered by Medicaid — such as personal care, home health aide hours, or a long-term care service. These denials may follow Medicaid fair hearing rules.

Coordination of benefits error. In integrated plans, Medicare and Medicaid are supposed to coordinate. If a service falls in a gap — denied by Medicare as "should be covered by Medicaid" and denied by Medicaid as "should be covered by Medicare" — you're caught in the middle. This is specifically the kind of coordination failure D-SNPs are supposed to prevent, and it is a legitimate ground for complaint and appeal.

Prior Authorization Denied: How to Appeal" class="auto-link">Prior authorization for complex services. Long-term services and supports (LTSS) and personal care services typically require extensive prior authorization, level of care determinations, and periodic reassessments. Denials here often involve clinical criteria about your functional limitations.

Incorrect enrollment or eligibility status. If your plan doesn't have your correct Medicaid status, you may be billed incorrectly or have services denied as if you were a non-Medicaid member.

Two Sets of Appeal Rights

This is the most important thing for dual eligibles to understand: you have Medicare appeal rights AND Medicaid fair hearing rights, and you can pursue both simultaneously.

Medicare Advantage Appeal Rights

For any service that falls under Medicare coverage, you follow the standard Medicare Advantage appeals process:

1. Organization Determination (initial decision)
2. Plan Reconsideration — file within 60 days; plan responds within 30 days standard / 72 hours expedited
3. Independent Review Entity (IRE) — automatic escalation if plan upholds denial
4. Administrative Law Judge (ALJ) — file within 60 days of IRE denial
5. Medicare Appeals Council
6. Federal District Court

Medicaid Fair Hearing Rights

For any service that falls under Medicaid coverage (including LTSS and personal care), you have the right to a fair hearing before a state administrative law judge or hearing officer. Key protections:

• You must receive adequate notice — typically 10 days before a benefit is reduced, suspended, or terminated
• If you request a fair hearing within 10 days of the notice, you typically have the right to continuation of benefits at the same level while the hearing is pending
• The hearing is free
• You can have a representative, advocate, or attorney

Contact your state Medicaid agency or your SHIP (State Health Insurance Assistance Program) counselor to initiate a Medicaid fair hearing.

When Both Apply

If a service sits at the intersection of Medicare and Medicaid coverage, file both a Medicare appeal and a Medicaid fair hearing request simultaneously. Document both filings. This creates two parallel review tracks and maximizes your chances of resolution.

Accessing Your Care Coordinator

Every D-SNP is required to assign you a care coordinator. This person's job is to help you navigate your benefits, coordinate your care across providers, and help resolve access problems. If you're experiencing a denial, contact your care coordinator. They can sometimes resolve coordination failures more quickly than a formal appeal.

If your care coordinator isn't responding or isn't helpful, escalate to member services and ask to speak with a supervisor or patient advocate.

Filing a Complaint With CMS and Your State

If your D-SNP is failing to coordinate your benefits properly, file a complaint:

• With CMS at Medicare.gov for Medicare benefit issues
• With your state Medicaid agency for Medicaid benefit issues

Dual eligible beneficiaries are a protected population that CMS monitors closely, and D-SNPs face additional oversight requirements.

Fight Back With ClaimBack

D-SNP denials can involve complex interactions between Medicare and Medicaid rules. ClaimBack helps dual eligible beneficiaries and their caregivers identify which set of rights applies, what documentation is needed, and how to build an effective appeal — whether the dispute involves Medicare, Medicaid, or both.
