Yes, the Dexcom G6 is being discontinued. Dexcom will stop manufacturing the G6 on July 1, 2026, and is actively encouraging users to switch to the Dexcom G7 or the newer Dexcom G7 15 Day before that date. Supplies may linger at pharmacies and distributors for a short time after manufacturing ends, but Dexcom cannot guarantee availability past that point.
Why Dexcom Is Phasing Out the G6
Dexcom has stated it needs to phase out the G6 to focus on delivering its next generation of continuous glucose monitoring (CGM) technology, including the G7 15 Day sensor. This isn’t an abrupt shutdown. It’s a gradual wind-down designed to give users, doctors, and distributors time to transition. Starting April 1, 2026, new users won’t be able to start on the G6 at all, reserving remaining supply for existing G6 users who haven’t yet made the switch.
What Changes With the G7
The G7 combines the sensor and transmitter into a single unit, so you no longer need to manage a separate transmitter that gets swapped every few months. The device is smaller and has a shorter warm-up time than the G6. However, a few practical differences matter for the transition.
Your G6 receiver will not work with G7 sensors. If you rely on a standalone receiver rather than a smartphone app, you’ll need a new one. The G7 works with the Dexcom mobile app and also has its own compatible receiver, but the hardware is not interchangeable between generations.
Insulin Pump Compatibility
If you use the G6 as part of an automated insulin delivery system, compatibility with the G7 is the most important detail to check before switching. The Omnipod 5 system now works with both the Dexcom G6 and the Dexcom G7, so Omnipod users can transition without changing their pump setup. Omnipod has confirmed it will continue supporting G6 integration for as long as G6 sensors remain available.
If you use a different pump system, check directly with your pump manufacturer and diabetes care team. Compatibility clearances can vary by device and region, and you don’t want gaps in your automated delivery coverage during the switch.
How to Handle the Transition
Dexcom is working with healthcare teams to coordinate the move from G6 to G7. You may be contacted by a Dexcom transition team before your next clinic appointment, but the simplest step is to bring it up with your doctor or diabetes educator at your next visit. They can write a new prescription for G7 supplies and help you understand any changes to your setup.
There’s no need to rush if you still have G6 sensors and transmitters on hand. Use what you have. But don’t wait until mid-2026 to start the process either. Getting a new prescription, confirming insurance coverage, and making sure your phone or receiver is compatible all take time. Dexcom recommends completing the upgrade by July 2026 to avoid any interruption in your CGM supply.
Insurance and Coverage Considerations
Both the G6 and G7 generally require prior authorization through insurance. Some plans updated their formularies in 2025 to list both G6 and G7 components, with prior approval required for either. The specific requirements vary by insurer, but insulin use is a common criterion for CGM approval regardless of which generation you’re on. Your doctor’s office typically handles the prior authorization paperwork, so the switch from G6 to G7 shouldn’t create a fundamentally different insurance experience for most users. That said, it’s worth confirming with your plan that the G7 is covered at the same tier before you run out of G6 supplies.
Key Dates to Know
- April 1, 2026: New users can no longer start on the Dexcom G6. Remaining inventory is reserved for existing users still transitioning.
- July 1, 2026: Dexcom stops manufacturing the G6 entirely. Supplies may be available through distributors for a limited time after this date, but availability is not guaranteed.
If you’re currently on the G6 and it’s working well for you, the transition to the G7 doesn’t need to feel disruptive. The core functionality, real-time glucose readings sent to your phone or receiver, stays the same. The main action item is making sure you have a G7 prescription and compatible supplies in place before the manufacturing cutoff.
