The sensors are worn on the skin and send glucose readings to a smartphone or other receiver for 10 days before they need replacing. Without insurance, the typical Dexcom G7 price is $579 for three sensors. There are no lower-priced generic versions, but there are ways to save money.

How much does Dexcom G7 cost without insurance?
Without health insurance, the average cash price for a 30-day supply of sensors (three sensors) is $579, about $190 per sensor. The annual Dexcom G7 sensor cost could add up to $6,900 or more. A receiver device that displays glucose data collected by the sensor is an optional part of the Dexcom G7 system; one’s cell phone can function in place of the receiver.
Although there are no lower-cost generic versions of the Dexcom G7 system, other continuous glucose monitor (CGM) sensors are available. These include the Dexcom G6, an earlier Dexcom CGM system without some of G7’s features. Other alternatives include Eversense, FreeStyle Libre, and Guardian personal CGM system sensors. While all these devices are effective options for glucose monitoring, the FreeStyle Libre CGM and Dexcom CGM are two of the most popular systems.
If the Dexcom cost is financially challenging, it’s likely that other CGM systems will be financially challenging, as well. The prescribing healthcare professional may have good medical advice about switching back to a standard blood glucose glucometer.

Is Dexcom G7 covered by insurance?
Dexcom G7 sensors are usually covered by insurance, Medicare, and Medicaid when certain criteria are met. Because of these qualifying criteria, it’s not uncommon for the insurance provider to require documentation from the prescriber (prior authorization) and a letter of medical necessity. Continued coverage often requires regularly visiting a healthcare provider for monitoring.
Insurance companies vary in how they cover Dexcom G7 sensors. Some insurance companies, such as Anthem, cover CGM systems as diabetic supplies, so they’re listed in a plan’s drug formulary. Other plans cover CGM systems as durable medical equipment (DME), such as Kaiser Permanente. These will be listed in a separate DME list. If you’re unsure or confused, contact an insurance representative directly.

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. The Dexcom Patient Assistance program can help some people, but not everyone is eligible. Fortunately, there are more certain ways you can lower the Dexcom G7 price if you don’t have insurance, starting with a SingleCare savings card:
1. Use a SingleCare prescription discount card
Using a SingleCare discount card can lower the retail price of three Dexcom G7 sensors from $579 to as low as $332 at Kroger. Discount prices, however, will vary by participating pharmacy. Keep in mind that you cannot use a SingleCare Dexcom G7 coupon with insurance; you can choose to use the coupon instead of insurance if your out-of-pocket expense is lower by doing so. For even more savings, sign up for SingleCare’s free bonus loyalty program and earn bigger discounts on refills or other future pharmacy purchases.
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. This is easy to do using the SingleCare app or website.
3. 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.
