Dexcom is a widely used continuous glucose monitoring (CGM) system. For many people living with diabetes, wearing a Dexcom sensor can almost eliminate finger sticks. Dexcom, like other CGMs, monitors your blood glucose (blood sugar) throughout the day and night, providing real-time updates.
How much does Dexcom cost?
Without insurance or discounts, Dexcom G7 (the newest version) can be expensive. The average cash price is about $581 for three 10-day sensors, a 30-day supply. There are 15-day sensors now available for $545 per month without insurance.
The total monthly cost of Dexcom G7 with a receiver and sensors is about $1,000 without insurance.

Does insurance cover Dexcom?
The majority of commercial health insurance plans cover Dexcom for people with Type 1 diabetes, according to Dexcom’s manufacturer.

Medicare Part B usually covers CGMs if you meet certain criteria. Criteria may include insulin use or low blood sugar episodes. Your healthcare provider will also need to confirm that you have been trained to use the device. This coverage can significantly lower your costs. People with Part B coverage will often pay a 20% coinsurance.
RELATED: Does Medicare cover diabetic supplies?
Note: Medicare Extra Help does not apply to Dexcom, but it can help reduce the cost of your diabetes medication. People who qualify for Extra Help may also qualify for other income-driven programs, such as Medicaid.
Medicaid coverage of Dexcom varies by state. Coverage of Dexcom may be limited to people with Type 1 diabetes or pediatric patients. Contact your plan provider for more information.
Benefits and copays vary widely across plans. Contact your insurance provider directly for more information about your exact coverage and costs.

2. Compare prices at local pharmacies
Prices may vary depending on your specific prescription details, pharmacy, and location. Use SingleCare’s app or website to find the pharmacy near you with the best price for your Dexcom device. For instance, in Hampton, VA (zip code 23666), you could save $88 on G7 sensors by simply switching pharmacies.
3. Skip the G7 receiver
Dexcom G7 sensors are compatible with smartphones, smartwatches, mobile tablets, or insulin pumps. Use a compatible device instead of buying a receiver to eliminate up to $581.
3. Manufacturer programs
The Dexcom Pharmacy Savings Program is limited to cash-paying customers who are uninsured or opt out of insurance coverage. The Dexcom Patient Assistance Program is income-based.
While manufacturer programs can be helpful, these offers can expire or be subject to other restrictions, like savings limits. SingleCare discounts are free, do not expire, and can be used on all refills with a valid prescription.
4. Switch to a cheaper alternative
There are many Dexcom alternatives available. Freestyle Libre is another popular option and may be cheaper than Dexcom G7.
Dexcom also makes the Stelo Glucose Biosensor System, an over-the-counter (OTC) CGM which doesn’t require a prescription. People who don’t typically meet coverage requirements, like those who don’t use insulin or have a risk of hypoglycemia, can use it.
Use SingleCare to save hundreds of dollars per month on a Dexcom G7, or to compare cheaper CGM systems. Ask your healthcare provider before you switch CGM systems.
Expert takeaway
“Managing diabetes can be overwhelming, and often people look for ways to simplify their treatment. Convenience is a huge factor for many people,” says Stephanie Melby, Pharm.D., a member of SingleCare’s Medical Review Board.
“Dexcom has some new improvements that may make it a better fit than other CGM brands,” says Melby. “Dexcom G7 has less parts to manage as the sensor and transmitter are now combined, and Dexcom G7 now has sensors that can be used for 15 days versus the previous 10 days.”
“Another huge factor is cost and access to CGMs like Dexcom. Communication with your diabetes healthcare provider is key to determining coverage and finding cost-saving opportunities,” she says.
