Dexcom G6 Discontinuation in 2026: Why & What Happens Next

If you rely on the Dexcom G6 to manage your diabetes, you’ll be shocked by the news that Dexcom G6 is being discontinued after years of trusted service. Many long-term G6 users are worried. Will their current supplies still work? Will insurance cover the upgrade? What comes next?

This guide answers every question you have, clearly and without confusion. You’ll learn exactly when the G6 phases out, why Dexcom made this decision, and how to make a smooth transition before it’s too late.

When Will Dexcom G6 Phase Out?

Dexcom G6 production ends on July 1, 2026. After that date, no new G6 sensors or transmitters will be manufactured. Limited stock may remain available through pharmacies and DME distributors for a short time after July 2026, but Dexcom cannot guarantee availability beyond that point.

Does Dexcom G6 still work after July 1, 2026? Yes, any existing G6 devices will continue to function normally after the production cutoff. The sensors, transmitters, and app will still operate. But once your supply runs out, no new stock will be available. This makes planning ahead critical.

Why Is Dexcom G6 Being Discontinued?

Dexcom’s decision isn’t arbitrary. Three clear reasons are driving the G6 phase-out:

1. Focus on future technology: Dexcom is discontinuing the G6 as part of its long-term product roadmap to prioritize the newer G7 and G7 15-Day CGM systems, which are designed to provide easier use, updated features, and improved overall performance.
2. Natural product evolution: As with past models, the G6 is being phased out when a next generation product (G7) becomes widely available, just like past Dexcom sensors were replaced by newer versions.
3. Official framing: Dexcom states that discontinuing the older model allows the company to focus on delivering the latest technology that supports users’ needs more efficiently.

Comparison of Dexcom G6 vs Standard G7 vs G7 15 Day

Before you switch, here’s exactly what’s different across all three sensors:

Important Notes:

• Dexcom G7 and G7 15 Day are marketed by Dexcom as “the most accurate on the market,” designed to replace the G6 line completely. It is only used for adults (18+), and for paediatrics, you can use a 10-day standard Dexcom G6.
• G7 has a faster warm up time and a smaller size compared to G6, enhancing comfort and convenience. Children of the age 2 and adults can use this standard sensor.
• G7 15 Day is cleared by the FDA for adult users and offers one of the longest continuous wear times in CGM systems.

Note for long-term G6 users:

The G6 allowed off-label sensor restarts, extending sensor life. The G7 doesn’t support sensor restarts, so long time G6 users should account for this when planning the transition.

What Happens to Dexcom G6 Pro After Discontinuation?

The G6 Pro is used in clinical and professional diabetes management settings for blinded glucose monitoring during patient assessments.
Unlike the consumer G6, there is currently no announced direct replacement for the G6 Pro. Healthcare providers relying on the G6 Pro should contact Dexcom directly to discuss their transition timeline. Clinics should plan their inventory accordingly and begin conversations with Dexcom’s professional team now.

How to Switch from Dexcom G6 to G7 or G7 15 Day

1. Talk to your doctor now about writing a new prescription for G7 or G7 15 Day before July 2026.
2. Check insurance coverage, most plans cover both G7 and G7 15 Day at parity with G6.
3. Order overlapping supplies to build a buffer so you don’t run out mid-transition.
4. Update the app/receiver if needed, update or replace your receiver for G7 compatibility.
5. Avoid gaps, use up remaining G6 supplies while gradually transitioning to the new system.

Tips for a Smooth Switch:

• Ask for a 90-day supply to reduce refill frequency.
• Make sure your pharmacy or DME supplier knows you want G7 15 Day sensors if eligible.
• If coverage is delayed, consider monthly refills with CGM Monitors.

Is Dexcom G7 Covered by Insurance If I Had G6?

In most cases, yes. Most commercial insurance plans, Medicare, and Medicaid cover the standard G7 and the 15 days G7, but prior authorization is often required. Dexcom’s provider resources state that most plans provide coverage parity for both systems, and Medicare patients using insulin or with a severe hypoglycemia history have full coverage for G7 15 Day.

CGM Monitors can help handle the full prior authorization process for you. Just fill out the free benefit check form on our website, and we’ll verify your eligibility and confirm your coverage so your G7 supplies can be shipped directly to you.

Can You Still Get Dexcom G6 Supplies Before They Run Out?

CGM Monitors currently stocks Dexcom G6 sensors, transmitters, and starter kits, available now with free nationwide delivery. If you want to bridge the gap before switching to G7, ordering through us is your most reliable option because CGM Monitors is the trusted DME supplier. On the other hand, retail pharmacies may have limited or inconsistent G6 availability as production winds down.

Smart Stocking Tips

1. Order a 1-2 month buffer now.
2. Set up a monthly refill subscription.
3. Check your insurance. Many plans will still cover G6 until July 2026.

What’s Next After the Dexcom G6 Phase-Out?

The Dexcom G7 is the natural upgrade for most G6 users. It’s smaller, more accurate, and faster to start than the older G6. For adults 18+, the G7 15 Day sensor cuts the replacement frequency nearly in half, a real convenience upgrade for daily diabetes management.

Other CGM Options Worth Knowing About

Not every user will want the G7, and that’s valid. Two strong alternatives exist:

• Abbott Freestyle Libre 3 Plus: A highly accurate CGM with a 15-day wear time and no separate receiver required. Available at CGM Monitors.
• Medtronic Guardian Sensor 4: Integrates tightly with the Medtronic 780 G insulin pump for a closed-loop experience.

Do you know?

Dexcom is already developing the G8, its next-generation CGM. The G6 phase-out is part of a long-term product roadmap, not just a reactive decision. G8 is in development and expected to push CGM accuracy and performance even further, making the G7 family a solid bridge towards future innovations.
