When to Start Your Renewal Process

Humana requires prior authorization renewal for Cresemba (isavuconazole) as of July 2025, with decisions made within 7 calendar days for standard requests starting January 2026. Here's when to begin:

Renewal Triggers

  • 30-45 days before expiration: Start gathering documentation
  • Clinical changes: New symptoms, treatment response, or adverse events
  • Lab abnormalities: Elevated liver enzymes or other safety concerns
  • Plan year transitions: January 1st formulary or coverage changes
Tip: Set a calendar reminder 60 days before your current authorization expires to allow time for documentation gathering.

New Humana members already taking Cresemba get a 90-day grace period without prior authorization, but must submit renewal documentation before this window closes.

Evidence Update Requirements

Your renewal must demonstrate continued medical necessity with current clinical evidence:

Required Clinical Documentation

  • Treatment response assessment: Clinical improvement or stability
  • Laboratory monitoring: Recent liver function tests (ALT, AST, alkaline phosphatase, bilirubin)
  • Infection status: Culture results, imaging studies, or biomarkers showing persistent disease
  • Adverse event monitoring: Documentation of tolerability and safety

Specific Lab Requirements

According to FDA labeling, monitor for:

  • Hepatic function: Baseline and ongoing assessment for liver injury
  • Drug interactions: Especially with CYP3A4 inhibitors/inducers
  • Treatment duration: Minimum effective duration with evidence-based continuation
From our advocates: "Patients who submit comprehensive lab panels and detailed response notes see faster renewal approvals. One patient's infectious disease specialist included serial CT scans showing gradual improvement—the renewal was approved within 3 days."
