Software Update Coming Soon!

t:slim X2 Insulin Pump with Basal-IQ Technology and Dexcom G6® CGM


We have decided to integrate the Basal-IQ feature with Dexcom’s new G6® continuous glucose monitor (CGM) approved earlier this year, to offer you a system that can predict and help prevent lows with zero fingersticks.1,2  We are actively working on this new integration and plan to begin rolling out software updates in August 2018.

All in-warranty t:slim X2 Pump users in the United States have the option to access the Basal-IQ feature free of charge via a software update using their personal computer.3  This update will require a prescription and online training before it can be downloaded, all of which will be coordinated through a simple-to-use online portal.



No action is required at this time.

In the next few weeks, when our new online portal is available, you will receive an email with instructions on how to get the process started. The process will consist of three steps:


Submit request online

We will email you when the online portal is ready, which you can then use to verify your contact information and request your prescription. Upon completion of this step, we will coordinate with your healthcare provider to get a signed prescription for the Basal-IQ feature and Dexcom G6 CGM.


Complete online training

Once the signed prescription is received from your healthcare provider, you will automatically be sent a link to the online training courses. Online training will take approximately 45 minutes to complete and must be completed before you can receive your software update.


Update your pump

When the software update is available, you will receive an email with your unique Update ID Code and instructions on how to add the new Basal-IQ feature to your insulin pump. We expect to begin distributing Update ID Codes by August 2018.
