The see a doc every six months is a Medicare requirement. Other insurance plans can have different requirements. The phone reps can’t tell what the actual requirements are. Try asking your doc’s office to take a look at your CGM data and update your chart. Might be enough. If not ask if you can do a virtual visit with a nurse sooner.
Couple of alternatives, if money isn’t a problem just pay out of pocket for the CGMs. I think US Med is the one DME company that makes that easy. See if Blue Circle Health - Now available in 20 states and Washington, D.C is available in your state. Check your health plan’s drug formulary for CGM coverage from your pharmacy. If money is an issue the cash price at a pharmacy is usually less then the DME companies, let us know if you want help finding the best price. A doc will still need to send a prescription.
