Step-by-step appeal flow

1
Pull your carrier policy bulletin
Express Scripts (PBM) publishes its Saxenda coverage criteria. Read it first — every successful appeal cites it back to the reviewer.
2
Document your medical necessity
PA criteria set by sponsoring plan, not Express Scripts directly Standard: BMI ≥30 + lifestyle documentation
3
Have your prescriber submit the PA
Most Express Scripts (PBM) PAs go through CoverMyMeds or the carrier portal. Your prescriber attaches BMI history, comorbidities (with ICD-10 codes), lifestyle program participation, and prior weight-loss attempts.
4
If denied — file the appeal within 60 days
Express Scripts is the pharmacy benefit manager — the underlying plan's PA criteria apply. Check the plan's coverage document; Express Scripts processes the appeal but doesn't set the criteria.
5
Submit external review if internal appeals fail
After two internal appeals, you can request external review through your state insurance commissioner. ERISA plans go through the federal external-review process.
