Dexcom G6 After July 2026: What Changes for Users

Dexcom G6 After July 2026: What Changes for Users

Dexcom stopped making the Dexcom G6 CGM System after July 1, 2026, and it says it can't guarantee how long pharmacies and medical distributors will still have G6 supplies [1]. As of October 2026, the G6 sensors people already have still connect to the major insulin pumps, but Dexcom is steering everyone to the Dexcom G7 or the Dexcom G7 15 Day [1]. Switching takes a new prescription or order and a new app. Some people will also need a new receiver.

What Dexcom announced

Dexcom's G6 transition page says the company "will no longer manufacture the Dexcom G6 CGM System after July 1, 2026" [1]. Supplies "may continue to be available through your local pharmacy or medical distributor for a period of time after that date," the page continues, "we cannot guarantee availability" [1]. The reason Dexcom gives is short: it wants to focus on its next sensors, including the G7 15 Day [1].

Here's what surprised us when we read the page in October 2026: its FAQ still asks G6 users to upgrade "by July 2026," a date that has already passed [1]. Any G6 box still on a shelf was made before production ended. Dexcom says it will keep supporting the G6 app and unexpired G6 supplies within their warranty period [1].

Why the G6 mattered, and what users are used to

The FDA authorized the G6 on March 27, 2018, through its De Novo pathway, and described it as an integrated continuous glucose monitoring system, or iCGM [2]. Its cleared use includes sending readings on its own to connected devices, including automated insulin delivery (AID) systems, which use CGM data to adjust a pump's insulin delivery [2]. Our article on iCGM regulatory standards explains the category.

The G6 pairs a 10-day sensor with a separate transmitter that clips onto each new sensor and is reused for up to three months; a receiver or phone app gets a reading every five minutes [2]. Each sensor starts with a two-hour warm-up [2]. And G6 parts don't mix with other generations: "Only use transmitters, receivers, and sensors from this system together" [2].

Which pumps and apps still work with G6

Dexcom says remaining G6 sensors keep connecting with Omnipod 5, Tandem t:slim X2, Tandem Mobi and the iLet Bionic Pancreas, and it asks people to use those sensors up with their pump before switching [1]. Insulet, which makes Omnipod 5, goes a step further: it "will continue to support integration with Dexcom G6 for as long as this sensor remains available" [3]. That's the nearest thing to an end date that any pump maker gives.

As of October 2026, Tandem's and Beta Bionics' pages focus on the G7 sensors and give no G6 end date [4][5]. Dexcom says the G6 works with the Tandem Mobi app [6]. For phone users, the switch is an app change: G6 app users download the Dexcom G7 app when they apply their first G7 sensor, and their account data transfers over [1].

What moving to G7 or G7 15 Day involves

Prescription or order. Both G7 sensors are prescription devices [7][8]. Dexcom tells people who pick up G6 supplies at a pharmacy to get a new prescription, and people supplied by a distributor to contact that distributor [1]. A durable medical equipment (DME) distributor "may be able to use your current order on-file" to switch you to G7, Dexcom says [6].

Wear time and warm-up. The FDA cleared the Dexcom G7 on December 7, 2022, for people ages 2 and older [7]. Each sensor lasts up to 10 days plus a 12-hour grace period for changing it, and warms up within 30 minutes (27 in FDA's comparison table) [7]. The Dexcom G7 15 Day, cleared on April 9, 2025, is for adults 18 and older. It lasts up to 15 days with the same grace period, and its warm-up is 60 minutes [8]. Both beat the G6's two hours [2].

Pairing. The biggest hands-on difference is the transmitter. On G7 it is molded into the sensor and used once, so there's no separate transmitter to reorder every three months [7]. FDA's G7 15 Day summary says the user pairs the display device with each new sensor to start a session [8]. The exact steps, including connecting to a pump, are in each device's own user guide.

Pumps. Dexcom says adults can use the G7 15 Day with iLet, Omnipod 5, Tandem Mobi and t:slim X2 [9]. Tandem says both of its pumps now pair with it [4], and Beta Bionics lists iLet with G7 15 Day as available [5]. One older answer on Dexcom's transition page still calls Tandem support "in progress," so confirm with Tandem [1]. Children and teens use the 10-day G7, which Dexcom says works with all four pumps [1]. Our article on interoperability with automated insulin delivery explains how these connections work.

Some setups need an update first. Dexcom says the t:slim X2 must run pump software 7.10.4 or later and the t:slim mobile app 2.12 or later [10]. Omnipod 5 users need Pods compatible with both G6 and G7 [9].

Receivers. Dexcom's receiver guide updates a Dexcom G7 receiver through Dexcom Clarity, and the update resets the receiver to factory settings [11]. One FAQ answer on the transition page says a receiver can be updated for G7 15 Day but names the G6 receiver, so ask Dexcom or your supplier whether yours qualifies [1]. The page also says the Dexcom G6 Touchscreen Receiver can't be updated, and that its users will need a new receiver from their supplier or by prescription to their pharmacy [1].

Coverage. Dexcom says that if your insurance covers G6, you will "likely" have coverage for G7 and G7 15 Day [1]. Coverage varies by plan, so check with your plan before your remaining G6 sensors run out.

What to ask, and where to check for updates

Ask your prescriber which G7 sensor fits you and whether you need a receiver prescription. Ask your pharmacy or DME supplier whether your current order can move to G7. Ask your pump maker which software version you need. Alert settings and other choices about managing glucose are decisions for you and your care team.

We'll keep re-reading the makers' own pages: Dexcom's G6 transition page [1], Insulet's Omnipod 5 sensor page [3], Tandem's Dexcom page [4] and the Beta Bionics home page [5]. FDA's records for the G7 (K213919) and G7 15 Day (K243214) hold the cleared indications [7][8]. Our overview of major US manufacturers and product lines covers the other sensor makers.

What nobody has published yet, as of October 2026, is a date when pumps or apps will stop accepting G6 sensors. Insulet ties its support to G6 availability [3], and Dexcom ties its support to supplies still under warranty [1].
