The American Association of Clinical Endocrinology (AACE) recommends real-time continuous glucose monitoring like Dexcom G7 for insulin-using adults ages 65 and older to achieve2:

  • Improved glycemic control
  • Reduced episodes of severe hypoglycemia
  • Improved quality of life





Studies show that Dexcom CGM is
proven to increase time in range3-7

Studies show that Dexcom CGM use is clinically proven to increase time in range.3-7 Time in range is a powerful supplement to A1C because it shows a more complete picture of changes in glucose levels. Since A1C is a three-month average, it doesn’t give insight into potentially dangerous high and low glucose variations.

Retrospective review of glucose data from Dexcom G6 can identify patterns of hyper- and hypoglycemia, as well as glycemic excursions to help guide treatment decisions.

Does my patient need to use his receiver?

Medicare requires the use of the receiver for all patients.  For all other payers, patients have the choice of what device to view their numbers. Users can also view their numbers on both their phone* and receiver if they choose. 

Can my patient use his/her new Dexcom G6 receiver with Dexcom G7? 

Yes, the new Dexcom G6 receiver can be upgraded from the G6 to the G7 CGM system once your patient has a G7 prescription and has received the product. To upgrade, please instruct your patient to first use a secure internet connection to upload his/her G6 data to by logging in with his/her Dexcom account information and clicking Upload. Then, Clarity will ask if he/she wants to upgrade the receiver from G6 to G7. Just click the boxes to confirm that all the requirements are met. Please note that by upgrading the receiver from G6 to G7 your patient will no longer be able to use Dexcom G6 sensors or transmitters with the new Dexcom G6 receiver and your patient will not be able to revert the receiver back to G6. Your patient may opt to update from G6 to G7 any time he/she chooses, just return to Clarity and upload to be asked again.

Will Dexcom provide diabetes testing supplies?

No. Blood glucose monitoring (BGM) supplies are not included in the CGM product shipments because Dexcom G6 and Dexcom G7 do not require fingerstick calibrations.* Any BGM testing supplies need to be purchased.   

*If your patient’s glucose alerts and readings from the Dexcom G6 or Dexcom G7 do not match symptoms or expectations, please use a blood glucose meter to make diabetes treatment decisions. 

How does my patient view glucose data? 

You can view your patient’s glucose data through the Dexcom G6 or Dexcom G7 Apps, your Dexcom G6 or Dexcom G7 receiver, and the Clarity Mobile or Desktop applications. 

Medicare does not cover Dexcom G6 or Dexcom G7 CGM supplies that are used only with a smartphone or other mobile device. Failure to use your receiver will result in loss of Medicare coverage for your Dexcom G6 or Dexcom G7 CGM supplies. 

What is the CMS policy?

Coverage of CGM system supplies and accessories are available for those therapeutic CGM systems where the beneficiary uses a receiver classified as DME to display glucose data. There is no Medicare benefit for supplies used with equipment that is not classified as DME. However, Medicare coverage is available for the CGM system supplies and accessories if a non-DME device (smartphone, smart watch, tablet, etc.) is used in conjunction with the durable CGM receiver. Coverage of CGM system supplies and accessories are available for those therapeutic CGM systems where the beneficiary uses a receiver classified as DME to display glucose data. If a beneficiary intends to never use a receiver classified as DME as the display device, the supplies and accessories are not covered by Medicare. 

Here are some examples of how a Medicare patient may use a smart device with their receiver: 

  • A patient uses both a receiver and a smartphone throughout the day 

  • A patient uses a receiver some days and their smartphone other days  

Patients should reach out to 1-800-MEDICARE with any questions about the Medicare coverage requirements for Dexcom CGM. 

How much can my Medicare patients expect to pay for Dexcom G6 and Dexcom G7 CGM Systems?

Generally, Medicare patients pay 20% out of pocket.  Many Medicare beneficiaries have supplemental insurance coverage such as Medigap that covers their out-of-pocket costs.
