Who Should Use This Guide

This checklist is designed for patients with confirmed or suspected homocystinuria and their healthcare providers seeking Cystadane coverage through any Blue Cross Blue Shield of Illinois plan. You'll need this if:

  • Your doctor has prescribed Cystadane for homocystinuria due to CBS, MTHFR, or cobalamin metabolism defects
  • You've received a denial or need to submit a prior authorization
  • You're preparing an appeal after an initial rejection

Expected outcome: With proper documentation, approval rates improve significantly when genetic confirmation, elevated homocysteine levels, and failed vitamin therapy are clearly documented.
