Who actually decides this
Not the logo on your card, most of the time. Three parties sit between you and the answer, and knowing which one is saying no tells you who to ask.

The pharmacy benefit manager · Express Scripts
This page is about the benefit manager itself. Express Scripts builds the formularies, so what is preferred, excluded or subject to step therapy on them is its decision. Which of its formularies you get, and whether weight-loss drugs are on your plan at all, is your plan sponsor’s choice. Insurers we cover that run on Express Scripts: Cigna.

Your employer, if the plan comes through work
Weight-loss drugs are usually a category an employer buys or declines, not something the insurer includes by default. That is why two people holding identical cards get opposite answers, and why the useful question for member services is whether your plan includes the weight-loss medication benefit at all, before anything about criteria.
How prior authorization works here
Six steps. Specifics come from the criteria above; where Express Scripts does not publish one, the step says what to ask for.
- 1
Confirm the benefit exists
Before any paperwork, ask whether your plan includes the weight-loss drug benefit. On whether a plan can leave it out, the documents say: Yes: only about half of Evernorth's employer clients cover Wegovy and Zepbound for weight loss.
- 2
Get the criteria in writing
Ask for the written prior authorization criteria for Wegovy, so your prescriber answers the plan's questions rather than guessing at them.
- 3
Your prescriber documents the clinical picture
BMI: BMI 30+, or 27+ with a weight-related condition (Cigna policy). Conditions: Hypertension, type 2 diabetes, high cholesterol, sleep apnea, heart disease, knee arthritis, asthma, COPD, fatty liver disease, PCOS. Lifestyle program: At least 3 months of diet and behavior change first, then continued alongside the drug (Cigna policy).
- 4
Answer step therapy, if there is any
Ask whether another drug must come first. If you have already tried one, the request should list it with dates and the reason it stopped.
- 5
Submit, then track it
Your prescriber sends the plan’s form with the notes. Our Wegovy prior authorization letter template covers the cover letter. Write down the date and the reference number, and ask how you will hear back.
- 6
Plan for the renewal
What the documents say: First approval lasts 8 months; 1-year renewals need 5%+ weight loss from baseline (Cigna policy).
Get your real answer
Log in at express-scripts.com (or call the number on your ID card) and check the drug under your plan, since your employer decides whether weight-loss drugs are covered. If it is covered, ask your prescriber to file prior authorization through esrx.com/PA.
Coverage is plan-specific: this page reports what Express Scripts publishes, not a promise about your plan. Not medical or insurance advice.
