Medical Necessity Documentation

Clinician Corner: Medical Necessity Letter Checklist

Your prescriber's letter should include:

Patient Information:

  • Age, weight, specific EB subtype (genetic confirmation)
  • ICD-10 codes: Q81.1 (junctional EB) or Q81.2 (dystrophic EB)
  • Wound locations, size, and healing status

Prior Therapies and Outcomes:

  • Specific dressings tried (brand names, duration)
  • Healing response or lack thereof
  • Adverse reactions or contraindications
  • Photographic documentation if available

Clinical Rationale:

  • Why Filsuvez is appropriate for this patient
  • Expected outcomes and monitoring plan
  • Dosing rationale (application with each dressing change)

Supporting Evidence:

  • FDA labeling for approved indications
  • Clinical trial data supporting efficacy
  • EB clinical guidelines from recognized organizations
From Our Advocates: We've seen faster approvals when prescribers include specific wound measurements and healing percentages. A letter stating "failed to heal after 8 weeks of silicone foam dressings with <10% wound size reduction" is more compelling than "standard care unsuccessful." This composite guidance reflects successful appeals across multiple similar cases.
