From Our Advocates: We've seen cases where the initial PA was denied because the clinic didn't clearly document that sapropterin was tried and failed (or contraindicated). Always include a clear timeline of prior therapies and their outcomes. This single detail can make the difference between approval and denial.

Common Denial Reasons & How to Fix Them

Denial Reason How to Overturn Required Documentation
"Not prescribed by specialist" Submit prescriber credentials Metabolic specialist certification, CV
"Concurrent sapropterin use" Clarify medication timeline Current med list, prior therapy dates
"Phe level not documented >600" Provide recent lab results Lab report within 3 months
"Age requirement not met" Confirm adult status Birth date, age verification
"Prior therapies not tried" Document diet/medication history Dietitian notes, failed med trials
"REMS not enrolled" Complete enrollment REMS confirmation certificate
