Since the Medicare rules changed for the second time in 2017, the Dexcom CGM supplies are only available through Dexcom. After the initial order, which took a lot of back and forth between Dexcom and the doctor, Dexcom sends this email once a month:
_In order to successfully receive Medicare reimbursement for the Dexcom G5 Continuous Glucose Monitoring (CGM) System, we are required to reach out to you on a monthly basis to verify your information. Please verify your product usage and refill needs in the link below in order to fulfill your next Medicare supplies order. _
If you do not verify your supply needs and information, you will not receive your next Medicare supplies shipment. Should you have any immediate questions about the Dexcom G5 Continuous Glucose Monitoring (CGM) System, please call 1-888-738-3646.
Please Note: The beneficiary may NOT use their phone or smart device for display of Continuous Glucose Monitoring (CGM) data and still be eligible for reimbursement by Medicare for Therapeutic CGM._

I fill out the quantity I have of the various items. In order to get a shipment of 5 sensors, I need to have none left; the one I am using is the last one. Even if it takes Dexcom only a day to process the order, it takes a few days to receive the shipment. If there is a weekend during that time, it is very possible/probable for the items to arrive on the last day of the 7 day sensor period, or later. That is a dangerous way of doing this. When Medicare did not cover the Dexcom CGM, my retirement supplementary coverage paid for everything and I was able to get more than 5 sensors at a time and order far enough in advance to receive the shipment before the last sensor’s 7 day run.
