When to Start Your Renewal Process

Humana typically approves Vitrakvi for 3-6 month periods, with most oncology medications requiring renewal every 3 months. Your approval timeline depends on your initial authorization and clinical response.

Renewal Triggers

  • 30-45 days before expiration: Ideal time to submit renewal
  • Disease progression on imaging: May require new treatment plan discussion
  • Significant toxicity: Could trigger dose modification or discontinuation
  • Insurance plan changes: Annual enrollment periods may affect coverage
Tip: Mark your calendar 45 days before your current approval expires. Late submissions can create treatment gaps.

Early Renewal Situations

Start your renewal process immediately if you experience:

  • Grade 3-4 liver function test abnormalities requiring dose holds
  • New neurological symptoms requiring evaluation
  • Upcoming travel that could delay submission
  • Plan to switch Humana products during open enrollment

Required Evidence for Renewal

Humana requires documentation of continued medical necessity for Vitrakvi renewal. Your oncologist must demonstrate ongoing clinical benefit and appropriate monitoring.

Clinical Response Documentation

Your renewal must include:

  • Recent imaging (CT/MRI within 8-12 weeks) showing response or stable disease
  • Clinical notes documenting performance status, symptom improvement, and quality of life
  • Objective response data using RECIST criteria when applicable
  • Adherence assessment including patient-reported compliance

Safety Monitoring Results

Liver function tests are mandatory for renewal:

  • ALT, AST, alkaline phosphatase, and bilirubin within 30 days
  • Documentation of any dose modifications due to toxicity
  • Management plan for ongoing side effects
  • Patient tolerance and ability to continue therapy

Molecular Documentation

Include your original NTRK fusion test results:

  • FDA-approved assay confirmation (FoundationOne, MSK-IMPACT, etc.)
  • Fusion partner identification
  • Confirmation of no acquired resistance mutations

Renewal Documentation Checklist

Must-Include Documents

  • Recent imaging report showing disease status
  • Laboratory results (liver function tests within 30 days)

Letter of Medical Necessity Template

Your oncologist should address:

  1. Current disease status: Response to therapy, symptom control
  2. Continued medical necessity: Why Vitrakvi remains appropriate
  3. Safety monitoring: Recent labs and toxicity management
  4. Treatment goals: Expected duration and endpoints
  5. Alternative options: Why other treatments aren't suitable

FAQ

How long does Humana prior authorization renewal take in Washington? Standard renewals take up to 30 days, but electronic submissions through the provider portal receive decisions within 1 business day for 95% of complete requests by 2025.

What if Vitrakvi becomes non-formulary on my Humana plan? You can request a formulary exception with medical necessity documentation. If denied, appeal through Humana's internal process, then Washington's external review system.

Can I request an expedited renewal appeal? Yes, if treatment delay would jeopardize your health. Expedited appeals must be decided within 72 hours by both Humana and Washington's IRO process.

Does step therapy apply to Vitrakvi renewals? Generally no for renewals if you're already responding to therapy. However, new restrictions could be added during annual formulary updates.

What happens if I miss the renewal deadline? Contact TRAK Assist immediately for bridge therapy while pursuing retroactive approval. Submit the renewal with explanation for the delay.

How do I know if my NTRK fusion test meets Humana's requirements? The test must be performed using an FDA-approved assay and clearly document the specific fusion. Contact your oncologist's office to verify your original test meets current requirements.
