When a therapeutic CGM is covered, the related supply allowance for sensors and transmitters are also covered.

 

Therapeutic CGM devices replace a standard home blood glucose monitor (BGM) and related supplies. Once billing starts for a CGM and the associated supply allowance, Medicare will no longer pay separately for a standard BGM and related supplies
