What do I do if I have lost or forgotten my Dexcom G6 sensor code?

If you do not enter a sensor code, you will be prompted to calibrate your Dexcom G6 CGM. You must enter your first two sensor calibrations on the same device, either the pump or the phone. After that, calibrations can be performed from either device for the remaining life of that sensor.

NOTE: It may take up to 15 minutes for the secondary device to register that a calibration was entered but it is not necessary to enter it on both devices.

Important note about Dexcom support:

Dexcom and Tandem have agreed which system issues are best handled by each company, including which company is responsible for reporting those events to the appropriate regulatory authority. To help ensure that the required reporting takes place in a timely fashion, customers may need to contact Dexcom for some issues and Tandem for others.

Tandem handles issues such as loss of connection (on pump only) and the invalid transmitter (Alert 29) on pump only.

For all other CGM issues, including would not accept calibration, the sensor failure during the 2-hour warmup, “no restarts” alert or physical problems with your sensor or transmitter, such as bleeding, bruising, skin reaction, adhesive issues, applicator issues, or broken wires, you should contact Dexcom using one of the options at dexcom.com/contact.
