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.
- 1
The pharmacy benefit manager
No single PBM to name here, which is itself the finding. Different plans under this name use different benefit managers, so one national statement about the formulary would be wrong.
- 2
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 Blue Cross Blue Shield 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: BCBS Michigan and BCN stopped covering GLP-1s for weight loss from 2025.
- 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
Current and baseline BMI, with dates. Any weight-related conditions, with diagnosis codes. Records of any diet, exercise or behavioral program.
- 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
Ask how long the approval lasts and what the renewal needs, so the gap does not catch you out.
Get your real answer
Log into your specific BCBS plan's member portal and run Wegovy through its own formulary or drug-cost lookup, then ask member services two questions: does my plan include the weight-loss (anti-obesity) drug benefit for 2026, and what are the prior-authorization criteria?
Coverage is plan-specific: this page reports what Blue Cross Blue Shield publishes, not a promise about your plan. Not medical or insurance advice.
