UnitedHealthcare requires prior authorization renewal for Koselugo (selumetinib) every 12 months for pediatric NF1 patients. Start renewal 30-60 days early with updated MRI showing stable/improved plexiform neurofibromas, specialist notes documenting continued benefit, and cardiac/eye monitoring results.

When to Start Your Koselugo Renewal

UnitedHealthcare typically approves Koselugo (selumetinib) for 12-month periods, but renewal isn't automatic. You'll need to demonstrate ongoing medical necessity and absence of disease progression.

Start your renewal process when you see these triggers:

  • 60 days before expiration - Ideal timing to gather all documentation
  • New symptoms or concerns - Even if renewal isn't due, contact your care team
  • Upcoming imaging - Schedule MRI scans to align with renewal timeline
  • Plan changes - If switching UnitedHealthcare plans or moving to/from Medicaid
Note: UnitedHealthcare has eliminated reauthorization requirements for many chronic disease medications as of 2025, but Koselugo still requires renewal due to its specialty status and monitoring requirements.

Signs you should start early:

  • Recent dose changes or treatment interruptions
  • New side effects requiring management
  • Upcoming transition from pediatric to adult care
  • Insurance plan changes at year-end

Evidence Update: What UnitedHealthcare Needs

For Koselugo renewal, UnitedHealthcare requires documentation that treatment continues to provide clinical benefit without unacceptable toxicity.

Response to Therapy Documentation

Primary requirement: Recent MRI reports showing stable disease or improvement - no evidence of progressive plexiform neurofibromas.

Clinical benefit measures:

  • Symptom improvement (pain reduction, better function)
  • Quality of life assessments from your care team
  • Photographic documentation of external tumors (if applicable)
  • Functional assessments (mobility, daily activities)

Safety Monitoring Results

Cardiac monitoring: LVEF assessments every 3-6 months showing maintained heart function above the lower limit of normal.

Eye exams: Regular ophthalmologic evaluations documenting absence of retinal complications like RPED or retinal vein occlusion.

Laboratory results: CPK levels and other routine monitoring labs within acceptable ranges.

Adherence Documentation

Your care team should document:

  • Medication adherence through pharmacy refill records
  • Proper dosing based on current body surface area
  • Management of any side effects
  • Patient/caregiver understanding of treatment goals

Your Renewal Packet: Must-Include Documents

Core Documentation Checklist

☐ Updated Letter of Medical Necessity from your specialist including:

  • Current diagnosis with ICD-10 codes (Q85.00 for NF1)
  • Imaging results showing stable/improved disease
  • Treatment timeline and response
  • Plan for continued monitoring

☐ Recent MRI Report (within 3-6 months) with volumetric analysis of target plexiform neurofibromas

☐ Cardiac Function Results - Recent echocardiogram or cardiac MRI showing stable LVEF

☐ Ophthalmologic Evaluation - Current eye exam results

☐ Medication History - Pharmacy records showing consistent fills and appropriate dosing

☐ Clinical Notes from recent specialist visits documenting ongoing benefit

Brief Letter of Medical Necessity Structure

Your specialist's renewal letter should address:

  1. Patient identification and confirmed NF1 diagnosis
  2. Current plexiform neurofibroma status with imaging correlation
  3. Treatment response since last approval
  4. Ongoing medical necessity and treatment goals
  5. Safety monitoring compliance and results
  6. Plan for continued care and monitoring schedule
Clinician Corner: Include specific measurements from imaging when possible. Phrases like "stable 15% volume reduction maintained" or "continued symptomatic improvement with stable imaging" strengthen renewal requests.
