The appeal, if you are denied

Denial reasons and fixes
Denial reason	What to send or ask
The plan excludes weight-loss drugs	This is a plan design choice. Ask your employer's benefits team whether weight-loss drugs will be included when the plan renews. Blue Cross Massachusetts says its exclusion cannot be appealed.
Criteria not met	Have your prescriber submit another request with your measured BMI and every weight-related condition listed in your chart
The drug is not on the plan's list	Request a formulary exception and ask which GLP-1 the plan favors as an alternative.

The denial letter names the exact rule that had not been satisfied. Get it.
Your prescriber files the appeal with chart notes that directly address that rule
If the plan’s own appeal fails, request an external review from an independent reviewer
