How to Coordinate Medicare and Medicaid After Hospital Discharge Without a Professional

Your parent was hospitalized for a fall, a stroke, or a sudden decline. Medicare Part A is covering the skilled nursing facility stay — but that coverage maxes out at 100 days, and the billing department is already asking what happens next. They want to know if you're going private-pay at $10,000+ per month, or if you have a plan.

Here's the plan, step by step, without hiring a professional.

The Timeline You're Working With

Medicare Part A covers skilled nursing facility (SNF) care for up to 100 days after a qualifying 3-day inpatient hospital stay. Days 1–20 are fully covered after any applicable Part A deductible. Days 21–100 require a daily copayment ($217 in 2026). After day 100, Medicare coverage ends entirely.

If your parent needs ongoing custodial care — help with bathing, dressing, eating, mobility — that's long-term care, and Medicare doesn't cover it. Medicaid does, but only if your parent meets the state's financial eligibility requirements.

The transition from Medicare-covered SNF to Medicaid-funded long-term care is where most families get blindsided. You're working against two clocks: Medicare's coverage countdown and Medicaid's application processing time (typically 45–90 days).

Step 1: Start the Medicaid Application Before Medicare Runs Out

Do not wait until day 90 to apply for Medicaid. Start the application process as soon as your parent enters the SNF — ideally within the first two weeks.

Financial inventory first. Gather every financial document: bank statements (60 months), investment accounts, retirement accounts, life insurance policies with cash value, property deeds, vehicle titles. Medicaid looks at countable assets — most states cap these at $2,000 (California is a notable exception at $130,000).

Check the asset limit. If your parent's countable assets exceed the state limit, you'll need a spend-down strategy before applying. Medicaid-compliant options include paying off legitimate debts, prepaying funeral expenses through an irrevocable funeral trust, making home repairs, and establishing a caregiver compensation agreement.

Submit the application. File through your state Medicaid office. Some states allow online submission; others require in-person filing or mailing. The application triggers a financial review that typically takes 45–90 days.

Step 2: Understand Who Pays First During the Transition

For dual-eligible beneficiaries, the payment hierarchy follows specific federal rules:

• Inpatient hospital: Medicare Part A pays first, Medicaid covers remaining cost-sharing (if the beneficiary has QMB, SLMB, or full Medicaid)
• Skilled nursing facility: Medicare Part A covers days 1–100 (with copay after day 20), then Medicaid covers long-term custodial care
• Home health: depends on whether the order originated from a Medicare provider or a Medicaid HCBS waiver — both programs cover home health, but through different channels
• Prescription drugs: Medicare Part D is primary; Extra Help/LIS reduces premiums and copays, with Medicaid's role depending on the dual-eligibility category and state

During the transition period — after Medicare SNF coverage ends but before Medicaid approval comes through — your parent may face a coverage gap. This is where a Qualified Income Trust (Miller Trust) becomes critical in states with income caps.

Step 3: Set Up a Miller Trust If Needed

In income-cap states such as Texas, Florida, Ohio, and Indiana, if your parent's gross monthly income exceeds 300% of the Federal Benefit Rate ($2,982 in 2026), a Qualified Income Trust is mandatory for long-term-care Medicaid — commonly called a Miller Trust.

A Miller Trust routes specified income through an irrevocable trust. Approved disbursements can include the patient pay-share, Medicare premiums, community spouse allowance, and personal needs allowance; the sequence and any remaining balance must follow state Medicaid and trust instructions, with the state Medicaid agency as primary remainder beneficiary.

State-approved forms may be available, but requirements vary. Because the trust must be drafted, executed, bank-established, and funded within the same calendar month for which eligibility is sought, consider a state-licensed elder-law attorney.

Step 4: Handle the SNF Billing Department

SNF billing departments will pressure you to sign a private-pay agreement as Medicare coverage winds down. Know your rights:

• Discharge is generally subject to federal transfer and discharge rules (42 C.F.R. § 483.15), but a pending application does not guarantee a bed hold or eliminate all payment obligations
• Ask the facility to confirm its Medicaid participation and applicable reimbursement rules; do not assume pending status makes it accept every payment arrangement

If the facility pressures you, document every interaction in writing. If they threaten discharge, contact your state's Long-Term Care Ombudsman — every state has one, and their services are free.

Step 5: Evaluate D-SNP Enrollment

A Dual Eligible Special Needs Plan (D-SNP) is a type of Medicare Advantage plan designed specifically for people with both Medicare and Medicaid. Depending on the D-SNP model and state, it may coordinate the two programs through aligned plans or leave Medicaid arrangements separate.

D-SNPs may include plan-specific supplemental benefits not available through Original Medicare, such as transportation to medical appointments, OTC allowances, dental and vision coverage, and meal delivery after hospital discharge.

Full-benefit dual eligibles can enroll in or switch highly integrated D-SNP plans once per month through the Integrated Care Special Enrollment Period, effective January 1, 2025, to align enrollment with an affiliated Medicaid managed care organization (MCO), subject to plan and state availability; enrollment takes effect on the first day of the following month. Other eligibility and plan rules apply.

Before enrolling, compare at least three D-SNP plans using the Dual Eligible Coordination Blueprint's comparison matrix. Check supplemental benefits, provider networks, and whether the plan includes care coordination services.

Step 6: Prepare for Ongoing Coordination

Hospital discharge isn't the end — it's the beginning of ongoing coordination between two programs. Prepare for:

• Annual Medicaid redetermination — states verify eligibility every 12 months. Have financial documents ready before the renewal packet arrives.
• QMB billing disputes — if your parent has Qualified Medicare Beneficiary status, Medicare-participating providers, suppliers, and pharmacies are legally prohibited from billing Medicare cost-sharing. Yet 1 in 4 QMB beneficiaries receive illegal bills.
• D-SNP annual review — plan benefits change every October during Annual Election Period. Review supplemental benefits and provider networks before auto-renewing.

Frequently Asked Questions

What happens if Medicaid hasn't approved by the time Medicare SNF coverage ends?

Apply early and track the application status. If coverage ends before Medicaid approves, the facility generally must follow federal transfer and discharge rules, but a pending application does not guarantee a bed hold or eliminate payment obligations. Contact the Long-Term Care Ombudsman and the state Medicaid agency about the facility's procedures and whether the state permits retroactive coverage; there is no universal three-month rule.

Do I really need a Miller Trust?

Only in an income-cap state, and when your parent's gross monthly income exceeds the applicable cap. Texas, Florida, Ohio, and Indiana are examples. Other states use "medically needy" or "spend-down" methodologies. Check your state's method before setting one up.

Can a hospital discharge planner help with all of this?

Discharge planners focus on clinical transitions — placing your parent in an appropriate facility and arranging follow-up care. They typically don't help with Medicaid applications, asset spend-down, Miller Trust setup, or D-SNP enrollment. They may provide referrals, but the administrative coordination falls to you.

Should I hire someone to manage this?

An elder law attorney ($300–$600/hour) or Certified Medicaid Planner ($3,000–$8,000) can handle the financial eligibility strategy. For the administrative coordination — the billing disputes, D-SNP decisions, redetermination prep, and day-to-day program management — a structured guide is the more practical and affordable path for most families.
