Dexcom G7 is a prescription-only, wearable, continuous glucose monitor (CGM) system that sends instantaneous glucose readings to a smartphone or other receiver every five minutes. It is approved for adults and children two years and older with Type 1 or Type 2 diabetes and women with gestational diabetes who are at risk of hypoglycemia (low blood glucose). The sensor is applied to the back of the upper arm, the abdomen, or, for use in children ages two to six years, the upper buttocks, and provides real-time glucose readings for 10 days. With the Dexcom G7 system, the sensor and transmitter are combined. You may also need to purchase a receiver, which displays your blood glucose values, or you can use an app on a compatible smart device, such as a smartphone. The typical cash price, without insurance, of a Dexcom G7 three-pack is $572. There is not a less expensive generic version of Dexcom G7, but there are ways to make CGM systems like the Dexcom G7 system more affordable.

How to get Dexcom G7 without insurance
CGMs, including the Dexcom G7, can cost more than traditional blood glucose monitors that require a finger stick. Manufacturer coupons and patient assistance programs are sometimes available, but not everyone is eligible for these discounts. Fortunately, there are ways you can lower the price of Dexcom G7 systems if you don’t have insurance. Here are ways to save money on Dexcom G7:
1. Use a SingleCare prescription discount card
Using a SingleCare discount card can lower the retail price of three Dexcom G7 systems from $550 to $301. A discount coupon is valid at over 35,000 pharmacies nationwide.
2. Compare pharmacy prices
The price of Dexcom G7 systems can vary from pharmacy to pharmacy. To find the lowest price, shop around and compare prices to find the most affordable option.
3. Manufacturer copay assistance and patient assistance programs
Dexcom G7 systems may be affordable even for those without insurance coverage. Dexcom, the manufacturer, offers a coupon, and qualifying patients can save $200 or more on the Dexcom G7 system. The Dexcom Patient Assistance Program offers discounts to eligible US residents who meet certain income criteria.
4. Discuss other continuous monitoring systems with your healthcare provider
While CGMs are convenient for blood sugar monitoring, they can be expensive without insurance coverage. Talk to your healthcare professional about competitors’ CGM systems, which may be less costly than the Dexcom G7. Also, traditional fingerstick blood glucose meters cost diabetes patients significantly less than CGMs. Your healthcare professional can provide medical advice and help you determine which blood glucose monitoring product is best for you.
