Renewal Triggers: When to Start the Process

Check Your Current Authorization Status

Your Vitrakvi approval letter from Humana contains critical dates. Look for:

  • Authorization end date (typically 6-12 months from approval)
  • Number of cycles approved (if applicable)
  • Renewal requirements listed in the approval language
Tip: Set a calendar reminder 6-8 weeks before your authorization expires to begin gathering renewal documents.

Signs You Should Start Early

Start the renewal process immediately if:

  • Your current authorization expires within 60 days
  • Recent imaging shows any change in tumor status
  • You've had dose modifications due to side effects
  • Your oncologist has changed or you've switched treatment centers
  • Humana has updated their formulary or PA requirements

According to Humana's Medicare prior authorization guidelines, standard PA decisions take up to 14 calendar days, with possible 14-day extensions if additional information is needed.

FAQ: Common Renewal Questions

Q: How long does Humana typically approve Vitrakvi renewals? A: Most oncology specialty drugs receive 6-12 month approvals. The exact duration depends on your response status and plan-specific policies.

Q: What if my imaging shows slight tumor growth? A: Document that changes don't meet RECIST 1.1 criteria for progression. Stable disease (less than 20% growth) typically supports continuation.

Q: Can I switch from CenterWell to my local specialty pharmacy? A: Check your plan's preferred pharmacy requirements. Some Humana plans require specialty drugs to be filled through CenterWell.

Q: What if my oncologist leaves the practice? A: Ensure medical records transfer includes your NTRK testing results and treatment history. The new oncologist will need this for renewal documentation.

Q: Does Texas Medicaid cover Vitrakvi differently than Humana Medicare? A: Yes, Medicaid has separate PA processes. This guide focuses on Humana Medicare Advantage and Part D plans.

Q: How do I know if my plan requires step therapy for renewals? A: Check your current PA approval letter and Humana's formulary. Patients already on therapy are typically exempt from new step therapy requirements.
