Submit complete documentation via fax (1-877-486-2621) or Humana provider portal. If denied, you have 60 days for internal appeal, then California's Independent Medical Review (IMR) through DMHC with a 61% success rate.

When to Start Your Renewal Process

Start 4-6 weeks before your current authorization expires. Humana typically approves Prolastin-C for 6-12 month periods, and you'll need fresh clinical evidence to demonstrate ongoing medical necessity.

Early Warning Signs to Begin Renewal:

  • Your specialty pharmacy mentions upcoming expiration
  • You receive a pre-expiration notice from Humana
  • It's been 10-11 months since your last approval
  • Your prescriber schedules routine monitoring labs
Tip: Set a calendar reminder 6 weeks before your expected renewal date. This gives you time to gather documentation without risking a coverage gap.

Required Documentation for Renewal

Your renewal packet must prove that Prolastin-C remains medically necessary and effective for your alpha-1 antitrypsin deficiency.

Core Clinical Requirements

Documentation Requirement Timing Source
AAT serum level <11 µM (80 mg/dL) Within 12 months Humana PA requirements
Spirometry (FEV₁) 30-65% predicted or rapid decline >100 mL/year Within 6 months Medicare PA guidelines
Chest imaging CT or X-ray confirming emphysema Recent (within 12 months) Humana PA requirements
Genotype confirmation Pi*ZZ documented (lifetime requirement) On file FDA labeling

Supporting Documentation Checklist

  • Updated medical necessity letter from prescriber
  • Treatment response summary (stable FEV₁, reduced exacerbations)
  • Current weight for dosing verification (60 mg/kg weekly)
  • Confirmation of no IgA deficiency with anti-IgA antibodies
  • Documentation of continued non-smoking status
  • Specialty pharmacy coordination letter

Clinician Corner: Medical Necessity Letter Elements

Your prescriber's renewal letter should address:

  1. Diagnosis confirmation: Alpha-1 antitrypsin deficiency with emphysema (ICD-10 codes)
  2. Treatment response: Stable or improved lung function, fewer exacerbations
  3. Ongoing need: Continued severe AAT deficiency requiring augmentation
  4. Monitoring plan: Regular spirometry and clinical assessments
  5. Alternative consideration: Why other AAT products aren't suitable (if applicable)

When to Escalate to IMR

  • Humana denies renewal citing "not medically necessary"
  • Step therapy requirements seem inappropriate for your case
  • Prior authorization requirements appear unreasonable
  • Coverage determination contradicts established medical guidelines
