Why Florida's New Insurance Laws Matter for Xospata Coverage
Florida's Patient Timely Access to Healthcare Act, effective October 2024, dramatically speeds up the appeals process for specialty drugs like Xospata (gilteritinib). Previously, insurance appeals could drag on for months. Now, Humana must resolve standard appeals within 30 days and urgent appeals in as little as 6 days.
This matters because Xospata, priced at approximately $29,000 per month, faces frequent prior authorization requirements and denials. The new law also requires insurers to process appeals seven days a week—weekends now count toward deadlines.
How State Rules Interact with Humana Policies
Humana Medicare Advantage plans in Florida must follow both federal Medicare regulations and Florida state insurance laws. This creates multiple layers of protection:
- Federal Medicare: 65-day appeal window, standardized forms
- Florida State: 30-day resolution requirement, expedited urgent reviews
- Humana Policy: Specific clinical criteria for FLT3-mutated AML
The strongest protection applies, so you benefit from whichever timeline is faster.
Prior Authorization Requirements: What Humana Needs
Coverage at a Glance
| Requirement | What It Means | Where to Find It | Timeline |
|---|---|---|---|
| Prior Authorization | Required for all Medicare Advantage HMO members | Humana PA List | 7 days (new CMS rule, Jan 2026) |
| FLT3 Mutation Test | Lab report confirming FLT3-ITD or TKD mutation | Your oncology clinic records | Must be FDA-approved test |
| Diagnosis Documentation | ICD-10 codes for relapsed/refractory AML | Medical records, pathology reports | Current episode of care |
| Prior Therapy Records | Evidence of previous treatments and outcomes | Clinic notes, infusion records | Last 6-12 months recommended |
Step-by-Step: Fastest Path to Approval
1. Gather Required Documents (Patient/Caregiver)
- Insurance card with Humana ID number
- FLT3 mutation test results (PCR or NGS)
- Complete diagnosis and staging information
- List of all prior AML treatments and outcomes
2. Coordinate with Your Oncologist (Clinic Staff) Submit through Humana's Availity portal or fax to 888-447-3430. Include:
- Provider TIN/NPI numbers
- Up to 6 diagnosis codes
- Clinical notes justifying medical necessity
- Treatment plan and monitoring schedule
3. Track Your Request Humana must respond within 7 days starting January 2026. Use their prior authorization search tool to verify current requirements.
4. Prepare for Possible Denial Common denial reasons include missing FLT3 documentation, use in newly diagnosed patients, or non-hematology prescribers. Have appeal documents ready.
Tip: If you're already taking Xospata from another plan, you may qualify for a 90-day transition period without prior authorization. Provide documentation of active treatment.
Step Therapy Protections and Medical Exceptions
Florida law requires insurers to offer clear step therapy override processes, though there's no blanket exemption for AML drugs. However, you have strong grounds for medical exceptions if:
Medical Exception Criteria
- Prior failure or intolerance to formulary alternatives like midostaurin
- FDA approval status - Xospata is specifically approved for relapsed/refractory FLT3+ AML
- Clinical contraindications based on your mutation profile or comorbidities
- Continuation from prior plan within the last 90 days
Documentation That Helps
When requesting step therapy exceptions, include phrases like:
- "Patient has documented FLT3-ITD mutation confirmed by [test name]"
- "Prior treatment with [drug] resulted in disease progression on [date]"
- "No FDA-approved alternatives exist for this specific mutation profile"
- "Delay in treatment poses imminent risk of disease progression"
Counterforce Health specializes in turning these clinical facts into targeted, evidence-backed appeals that align with payer policies. Their platform can help identify the specific denial basis and draft point-by-point rebuttals using the right medical citations and clinical documentation.
Continuity of Care During Plan Transitions
Ongoing Therapy Protections
If you're switching to Humana from another plan while taking Xospata:
First 90 Days: Humana cannot require new prior authorization if you provide:
- Previous plan's approval letter
- Current prescription and dosing
- Treating physician's continuation order
- Medical records showing stable or improving condition
Grace Period Supplies: Request temporary fills while authorization is pending. Florida law supports continuity for life-threatening conditions like AML.
Renewal Timelines: Annual authorizations typically renew automatically if your condition and treatment remain stable. Humana must notify you 30 days before any coverage changes.
Appeals Process: Internal to External Review
Appeals Playbook for Humana in Florida
| Level | Timeline | How to File | Required Documents |
|---|---|---|---|
| Internal Appeal | 65 days to file, 30 days resolution | Humana member portal or 800-523-0023 | Denial letter, medical records, prescriber statement |
| Expedited Appeal | 65 days to file, 6 days resolution | Same as above, mark "URGENT" | Evidence of immediate health risk |
| External Review | 4 months after final denial | Florida Department of Financial Services | Complete appeal file, independent reviewer assignment |
When to Request Expedited Review
For Xospata appeals, expedited review applies when:
- Your AML is progressing rapidly
- Delay could result in hospitalization
- You're experiencing severe symptoms
- Your oncologist documents immediate medical need
Note: External review in Florida is free and binding. Independent medical experts not affiliated with Humana make the final decision.
Practical Scripts for Calls and Letters
Patient Phone Script for Humana
"Hi, I'm calling about a prior authorization denial for Xospata, generic name gilteritinib, for my FLT3-positive acute myeloid leukemia. My member ID is [number]. I need to file an internal appeal under Florida's Patient Timely Access to Healthcare Act, which requires resolution within 30 days. Can you transfer me to the appeals department and provide the reference number for this case?"
Clinic Staff Script for Peer-to-Peer
"I'm requesting a peer-to-peer review for [patient name] regarding Xospata denial. This patient has relapsed FLT3-ITD positive AML confirmed by [test name] on [date]. They failed prior therapy with [drugs] and have no FDA-approved alternatives. The delay poses immediate risk of disease progression. When can we schedule the clinical review?"
Medical Necessity Letter Checklist
Your oncologist's letter should include:
- Problem: Specific FLT3 mutation type and AML staging
- Prior treatments: Dates, drugs, response, and reason for discontinuation
- Clinical rationale: Why Xospata is the appropriate next step
- Guideline citations: NCCN guidelines, FDA labeling, peer-reviewed studies
- Dosing plan: 120 mg daily, monitoring schedule, response criteria
- Monitoring: Labs, imaging, toxicity assessments planned
When Self-Funded Plans Are Different
Some Humana plans are self-funded by employers and governed by federal ERISA law rather than Florida state regulations. This means:
Different timelines: May not follow Florida's 30-day appeal requirement Limited state protection: Florida insurance laws may not apply Federal appeals: Must follow Department of Labor procedures
How to tell: Check your plan documents or call Humana. Self-funded plans often have different member ID formats or say "Administrative Services Only" on materials.
If you have a self-funded plan: You still have appeal rights under federal law, but Florida's expedited timelines may not apply. Focus on federal Medicare protections instead.

What if Xospata is non-formulary on my plan? Request a formulary exception with your prescriber's statement that covered alternatives won't work or cause adverse effects.
Can I request expedited appeal if my AML is progressing? Yes. Document immediate health risk and mark all submissions "URGENT." Florida law requires resolution within 6 days for urgent cases.
