How to Get Ferriprox (deferiprone) Covered by Humana in Illinois: Complete Guide with ICD-10 Codes, Prior Authorization, and Appeals
Answer Box: Getting Ferriprox (deferiprone) Covered by Humana in Illinois
Ferriprox (deferiprone) requires prior authorization from Humana and is typically covered as a specialty Part D drug when medically necessary for transfusional iron overload. Fastest path to approval: Have your hematologist submit a PA request with diagnosis codes E83.111 (transfusional iron overload) plus your underlying condition (D56.- for thalassemia, D57.- for sickle cell), recent ferritin levels, transfusion history, and documentation of failed or contraindicated alternative chelators. Start today: Call Humana at the number on your insurance card to confirm formulary status and request PA forms.

Coding Basics: Medical vs. Pharmacy Benefit Paths
Ferriprox (deferiprone) is almost always covered under Part D pharmacy benefits rather than Part B medical benefits. This distinction affects how the drug is coded and billed.
Pharmacy Benefit Path (Most Common)
- Coverage: Medicare Part D or Medicare Advantage Part D
- Coding: Uses NDC numbers for billing
- Prior Authorization: Required through Humana's pharmacy benefit management
- Dispensing: Specialty pharmacy (CVS Specialty, Accredo, etc.)
Medical Benefit Path (Rare)
- Coverage: Only when specifically allowed by plan policy
- Coding: HCPCS J3490 (unclassified drug) with NDC documentation
- Billing: Provider submits claim with medical justification
Note: Always verify benefit determination with Humana before assuming medical benefit coverage, as this is uncommon for oral iron chelators.
ICD-10 Mapping for Transfusional Iron Overload
Accurate diagnosis coding is critical for Ferriprox approval. Use these ICD-10 codes based on your clinical documentation:
Primary Iron Overload Codes
- E83.111 - Hemochromatosis due to repeated red blood cell transfusions
- Use when documentation explicitly states "transfusional hemochromatosis"
- Most specific code for transfusion-related iron overload
- E83.10 - Other disorders of iron metabolism
- Use for "secondary iron overload" or "iron overload due to transfusions"
- Appropriate when hemochromatosis is not specifically documented
Underlying Hematologic Conditions
Always pair iron overload codes with the primary condition:
| Condition | ICD-10 Code | Documentation Requirements |
|---|---|---|
| Beta-thalassemia major | D56.1 | Specify major vs. intermedia |
| Sickle cell disease | D57.00, D57.1, D57.2 | Include crisis status if applicable |
| Other thalassemias | D56.8, D56.9 | Document specific type when known |
Supporting Documentation Language
To support these codes, clinical notes should include:
- "Secondary iron overload due to chronic transfusions"
- "Transfusional iron overload in patient with beta-thalassemia major"
- "Iron accumulation from repeated RBC transfusions"
Product Coding: HCPCS, NDCs, and Billing Units
HCPCS Coding (Medical Benefit)
When Ferriprox is covered under medical benefits (rare):
- J3490 - Unclassified drugs
- Billing unit: 100 mg increments
- Documentation: Must include NDC, strength, and total units
NDC Numbers (Pharmacy Benefit)
Ferriprox NDCs from Chiesi Global Rare Diseases:
| Strength | NDC | Package Size |
|---|---|---|
| 500 mg tablets | 59923-0125-01 | 100 tablets |
| 1000 mg tablets | 59923-0125-02 | 100 tablets |
| Oral solution 100 mg/mL | 59923-0126-01 | 120 mL bottle |
Units Calculation
- Dosing: 75-99 mg/kg/day divided into 2-3 doses
- Example: 60 kg patient at 75 mg/kg/day = 4,500 mg daily
- Monthly supply: ~135,000 mg = 1,350 billing units (100 mg each)
Clean Prior Authorization Anatomy
A successful Ferriprox PA request to Humana should include these elements:
Required Clinical Information
- Patient demographics and Humana member ID
- Diagnosis codes: E83.111 + underlying condition (D56.-, D57.-)
- Prescriber information: Hematologist/oncologist preferred
- Drug details: Ferriprox (deferiprone), strength, quantity, days supply
Supporting Documentation
- Ferritin levels: Recent results showing iron overload (typically >1,000 ng/mL)
- Transfusion history: Duration, frequency, total units received
- Prior chelation therapy: Trials of deferasirox, deferoxamine with outcomes
- Contraindications: Document why other chelators aren't suitable
- Monitoring plan: ANC monitoring due to agranulocytosis risk
Medical Necessity Statement
Include language such as: "Patient has transfusional iron overload due to chronic RBC transfusions for beta-thalassemia major. Previous trial of deferasirox resulted in [specific outcome]. Ferriprox is medically necessary to prevent iron-related organ damage."
Common Coding Pitfalls to Avoid
Diagnosis Coding Errors
- Don't use E83.11 (hereditary hemochromatosis) for transfusional iron overload
- Don't omit the underlying hematologic condition code
- Don't use R79.0 (abnormal blood chemistry) when true iron overload is present
Product Coding Issues
- Unit conversion errors: Remember 100 mg = 1 billing unit for J3490
- Wrong NDC format: Use 11-digit format (5-4-2) not 10-digit
- Missing modifiers: Include appropriate modifiers when billing J3490
Documentation Gaps
- Vague language: "Iron problems" vs. "transfusional iron overload"
- Missing dates: Always include when transfusions started
- Incomplete monitoring: Must address ANC monitoring plan
Verification with Humana Resources
Check Formulary Status
- MyHumana portal: Log in and search "Ferriprox" or "deferiprone"
- Medicare Plan Finder: Enter drug name and compare plans
- Pharmacist consultation: Have your pharmacy run a benefits check
Confirm PA Requirements
- Prior authorization: Required for most Humana plans
- Step therapy: May require trial of other chelators first
- Quantity limits: Verify maximum days supply allowed
- Specialty pharmacy: Confirm required dispensing channel

FAQ: Ferriprox Coverage with Humana
How long does Humana prior authorization take in Illinois? Standard PA decisions are made within 30 days for pre-service requests. Expedited reviews (when delay could harm your health) are decided within 72 hours.
What if Ferriprox is not on Humana's formulary? You can request a formulary exception with documentation showing medical necessity and why formulary alternatives aren't appropriate. Your doctor must provide supporting clinical evidence.
Can I appeal if step therapy is required? Yes. If you've already tried required first-line chelators or have contraindications, document this thoroughly. You can also request a step therapy exception if other chelators are clinically inappropriate.
Does Humana require specialty pharmacy for Ferriprox? Most Humana plans require specialty pharmacy dispensing for high-cost drugs like Ferriprox. Common networks include CVS Specialty, Accredo, and OptumRx Specialty.
What are typical out-of-pocket costs? Ferriprox is usually on a specialty tier (Tier 4 or 5) with coinsurance rather than flat copays. Under Medicare Part D, your total out-of-pocket costs are capped at $2,000 annually starting in 2025.
How do I request an expedited appeal? Have your prescriber submit a written request stating that delay in treatment would seriously jeopardize your health. Include specific medical reasons why waiting 30 days for standard review could cause harm.
