Prior Authorization (PA): complete reference

Prior authorization (PA) is an insurance requirement that a prescriber justify medical necessity для a specific medication before insurance will cover it. For GLP-1 medications, PA is typical для weight indications (sometimes для diabetes индicaations too). Documentation typically required: BMI ≥30 (or ≥27 с comorbidity), recent A1C if diabetic, 3-6 months of documented lifestyle intervention failure, failed prior weight-loss medications, contraindication screening (no MTC/MEN 2 history). Submission process: prescriber portal → 24-72 hour turnaround → approval, denial с rationale, or request for additional info. Denials are common первое раз; appeal protocol involves: written denial reason, formulary exception request с medical necessity letter citing FDA label + clinical guidelines + patient-specific factors, escalation to external review if denied again. Many initial denials reverse on appeal with proper documentation. PA expiration: typically 6-12 months; renewal required at expiration.

In practice

Your prescriber writes для Wegovy → pharmacy says "needs prior auth" → prescriber's office submits forms → 2-3 days later you get approval or denial. If denied, your prescriber can appeal with stronger documentation.
