A continuous glucose monitor is a small wearable device system that tracks your glucose throughout the day and night, notifying you of highs and lows so you can take action when needed. Continuous glucose monitoring (CGM) helps many people with diabetes obtain greater insight into what is happening with their blood sugar levels and trends.
Benefits of CGM
- The CGM system monitors blood glucose levels in the interstitial tissue every five minutes, offering much more information than four to eight finger sticks per day.
- CGM is very useful when you are struggling with nighttime lows, providing alarms and alerts.
- Continuous glucose monitoring is great for pediatrics because their parents and caregivers can remotely monitor the CGM data from their smartphones.
- Both Medtronic and Dexcom sensors and transmitters are water-resistant, if not waterproof. They are both relatively small and discreet to wear.
CGM & Insurance Coverage
- Most commercial insurances cover CGM, and the end of the year is a good time to consider CGM since at this time deductibles are often satisfied.
- Most insurances require a prior authorization on file, so it is essential that patients meet with their endocrinologist to discuss CGM. This is a good first step for obtaining a CGM system.
- Currently, no Michigan Medicaid plans consistently approve CGM, and plans will require a pre-authorization if the CGM is covered.
Starting with CGM
- It is easy to begin using CGM, and you don’t have to commit to an insulin pump. Many patients using multiple daily injections (MDI) report that they get tighter blood glucose through the combination of MDI and CGM.
- From start to finish, a CGM enrollment will take commercial members roughly 1-14 days and Medicaid members 2-4 weeks.
