Express Scripts pharmacy: How to get weight loss meds like Wegovy approved

When you need a prescription weight loss drug like Wegovy, a GLP-1 agonist used for obesity and type 2 diabetes, your insurance might require prior authorization, a process where your doctor proves the drug is medically necessary before coverage kicks in. Express Scripts pharmacy, one of the largest pharmacy benefit managers in the U.S. that manages prescriptions for many U.S. health plans is often the middleman handling these requests. If your plan uses Express Scripts, getting approval isn’t just about filling out forms—it’s about understanding their rules, avoiding common mistakes, and knowing what to do when they say no.

Most denials happen because the paperwork doesn’t clearly link your medical history to the drug’s approved uses. For example, Wegovy is approved for adults with obesity (BMI ≥30) or overweight (BMI ≥27) with at least one weight-related condition like high blood pressure or type 2 diabetes. If your doctor just says "weight loss" without mentioning the comorbidity, Express Scripts will reject it. You also need proof you’ve tried lifestyle changes first—like diet, exercise, or counseling—over a 3- to 6-month period. Many people don’t realize their doctor needs to submit lab results, BMI records, or even a signed statement from a nutritionist. If you’ve been denied before, you’re not alone. Nearly 40% of initial Wegovy requests get turned down by Express Scripts. But appeals work. You just need the right evidence.

Other weight loss drugs like semaglutide, the active ingredient in Wegovy and Ozempic, used off-label for weight management follow the same approval path. Even if you’re on a different plan, Express Scripts often sets the standard. Some people try switching to Hers Health or Amazon Pharmacy to skip the process, but those options usually cost more out-of-pocket. The real solution? Work with your doctor to build a solid case before submitting. Keep copies of every test, every note, every diet log. If your claim gets denied, don’t give up—file an appeal with your doctor’s help.
