Continuous Glucose Monitors (CGM)

A continuous glucose monitor is a small sensor worn on the arm or abdomen that checks your glucose every few minutes, day and night, and sends readings to your phone or a reader. Most people no longer need routine fingersticks once they are using one.

Why a CGM helps

• See how food, exercise, stress, and medications affect your glucose in real time.

• Get alerts for highs and lows, including overnight.

• Track "time in range," a simple target you and your doctor can follow between visits.

• Share data with your care team, which makes telemedicine visits more productive.

Common options

The main prescription systems in the US come from Dexcom (the G7 family) and Abbott (the FreeStyle Libre family). Some people who do not use insulin may also consider over-the-counter sensors. The right choice depends on your treatment, your phone, your insurance, and whether you use an insulin pump.

Insurance coverage

Many commercial plans and Medicare cover a CGM for people with diabetes who use insulin or have a history of problematic low blood sugars, and coverage is expanding. Coverage rules and copays vary by plan, so we will help check yours. Manufacturer programs can also lower the cost; see our Savings Programs.
