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

  1. Patient demographics and Humana member ID
  2. Diagnosis codes: E83.111 + underlying condition (D56.-, D57.-)
  3. Prescriber information: Hematologist/oncologist preferred
  4. 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

  1. MyHumana portal: Log in and search "Ferriprox" or "deferiprone"
  2. Medicare Plan Finder: Enter drug name and compare plans
  3. 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.
