Part B will insta-approve a CGM refill. Its on the supplier, Walgreens in this case, to make sure they have the documentation you mention to survive a medicare audit. Wags outsources the documentation part and that’s who the store is waiting on. Changing pharmacies is a solid plan while Wags finishes falling apart.
@SherryAnn asked if anyone has used Fairview. Maybe @mohe0001 knows someone who knows about them.
