Dexcom is a widely used continuous glucose monitoring (CGM) system. For many patients living with Type 1 or Type 2 diabetes, wearing a Dexcom can almost eliminate finger sticks (although they may still be needed occasionally). Dexcom, like other CGMs, monitors your blood glucose, or blood sugar, throughout the day and night, giving you continuous updates on your glucose data in real time. 

How much does Dexcom cost?

Without insurance or discounts, Dexcom G7 (the newest version) can be expensive. The average cash price is about $577 for three boxes of 10-day sensors, a 30-day supply. (An even newer version of the G7, with sensors lasting 15 days, is expected to be available in the United States before the end of 2025, but pricing is not yet available.) 

If you have insurance, whether through a commercial insurance plan, Medicare, or Medicaid, your cost for Dexcom will vary. The drug’s manufacturer has an online tool you can use to see whether your plan covers Dexcom, noting that most people with Type 1 diabetes and commercial health insurance have coverage. 

Medicare Part B may provide coverage for Dexcom if you meet the criteria, such as using insulin or having hypoglycemic (low blood sugar) events. Medicaid coverage varies by state. You can reach out to your specific state plan for more information. 

You can contact your specific plan for more information on Dexcom coverage and cost. Note that some plans may require prior authorization in order to cover Dexcom. 

How to save money on Dexcom

If your insurance plan does not cover Dexcom, or if your price with insurance is still expensive, there are some other ways you can save money on the Dexcom CGM. 

1. Free Dexcom coupons

SingleCare is a savings program that is free to use. SingleCare cards and coupons are accepted at over 35,000 participating pharmacies in the U.S. and Puerto Rico. As mentioned above, the average retail price for 3 boxes of Dexcom G 7 sensors (a 30-day supply) costs about $577. However, you can use a free SingleCare coupon to pay as low as $321 for your prescription, a savings of $256 per month. What’s more, you can use the discount on your initial prescription fill as well as refills. 

Additionally, you can use the Dexcom G7 sensor with your mobile Dexcom Clarity app—but if you prefer, you can use a receiver instead of your smartphone or compatible smart device. You can use a SingleCare discount to save on this purchase, too. Without insurance, a Dexcom receiver for the G7 costs about $435, but you can use your SingleCare card or coupon to pay as low as $228, a savings of $207. 

Prices may vary depending on your specific prescription details, pharmacy, and location. You can check with your local participating pharmacy for more information about your discount with SingleCare. The table below shows example pricing for both G7 and G6 (the previous model) sensors and receivers.

Dexcom G7 receiver	$435 for 1, Dexcom G7 receiver	$228 for 1, Dexcom G7 receiver	Get coupons

Dexcom G6 transmitter*	$366 for 1, Dexcom G6 transmitter	$184 for 1, Dexcom G6 transmitter	Get coupons

*Dexcom G7 sensors include a built-in, disposable transmitter. Dexcom G6 sensors require a separate transmitter (replaced every three months) that is moved from one sensor to the next.

2. Medicare or Medicaid savings

Medicare Part B may provide CGM coverage if you meet certain criteria, such as using insulin or having low blood sugar episodes. Your healthcare provider will also need to confirm that you have been trained to use the device. This coverage can lower your costs significantly. 

Some people who qualify for Medicare Extra Help for prescription drug costs may also qualify for other programs, such as Medicaid, that can reduce or eliminate their costs for Dexcom. 

Medicaid coverage for Dexcom varies by state. Some states may cover only the G7 or G6, or both, and prior authorization may be required. 

Because benefits and copays can vary widely, it’s best to contact your insurance provider directly for more information about your exact coverage and costs. 

3. Manufacturer savings

You may be able to save on Dexcom through the manufacturer. First, you can check the website for a free sensor. This offer only applies to new Dexcom G7 users. You’ll need a prescription from a healthcare provider and you will have to meet certain criteria, which can be found on the manufacturer’s website. This may be a good option for those who want to try the Dexcom G7 to see if it is right for them before purchasing a larger quantity.

Dexcom also offers a savings card that can be used on Dexcom products (both G6 and G7), allowing you to save $210 on every 30-day supply of sensors. While this may be helpful, these offers can expire or have other restrictions. SingleCare discounts are free, do not expire, and can be used on your initial prescription as well as refills. Ask your pharmacy staff to compare the SingleCare price to the Dexcom savings card so you can choose the most affordable option.  

4. Patient assistance program

Patient assistance programs (PAPs) offer financial support or free products and medications to people who qualify based on income. Dexcom offers a PAP to residents of the U.S. who meet certain income eligibility criteria. An application and other information can be found through the Dexcom website. 

5. Ask about a 90-day supply

If you are paying out of pocket, some pharmacies may offer a discount if you purchase a three-month supply rather than a one-month supply. If you do not have insurance coverage, it may be a good idea to call around to a few local pharmacies to compare prices for a one-month versus a three-month supply.

Is there a cheaper alternative to Dexcom?

If you are interested in an alternative to Dexcom, there are some other options you can discuss with your healthcare provider. 

For example, the Freestyle Libre 3 is a CGM made by Abbott Diabetes Care, which may cost less than the Dexcom CGM system, depending on your coverage. Dexcom also makes the Stelo Glucose Biosensor System, a CGM that does not require a prescription and can be used in adults with Type 2 diabetes or prediabetes who do not use insulin or have a risk of hypoglycemia. 

You can use SingleCare to save over $250 per month on a Dexcom G7, or explore other savings options. Consult your healthcare provider if you are having trouble affording Dexcom, to review your options, or for medical advice on your condition and treatment.
