Medical Necessity Documentation

Clinician Corner: PA Letter Essentials

Your medical necessity letter should include these key elements:

Clinical History:

  • Confirmed cystinuria diagnosis with quantitative urine cystine levels
  • Stone composition analysis showing cystine stones
  • Recurrence pattern and stone burden

Prior Treatments:

  • Specific conservative measures tried (fluid intake targets, alkalinization agents, dietary changes)
  • Duration of each intervention and reasons for inadequacy
  • Any adverse effects or contraindications to alternatives

Clinical Rationale:

  • Reference to FDA labeling for cystinuria indication
  • AUA or international guidelines supporting tiopronin use
  • Patient-specific factors favoring Thiola/Thiola EC over alternatives
From Our Advocates: We've seen PA approvals significantly improve when providers include specific urine cystine reduction targets (typically <250 mg/day) and reference published efficacy data showing tiopronin's stone prevention rates. This demonstrates clear treatment goals and evidence-based prescribing.
