Continuous Glucose
Monitoring Systems
Dexcom empowers people with diabetes through two industry-leading CGM systems. Real-time glucose data without fingersticks, covered by Medicare, and fully integrated with the CCN Health platform.

How It Works
Easy 1-2-3 Setup
Apply the sensor, start tracking, and let the data guide treatment decisions.
Apply the Sensor
A small, water-resistant sensor is applied to the back of the upper arm or abdomen. The auto-applicator makes insertion quick and virtually painless.
Continuous Glucose Tracking
The sensor measures glucose levels every five minutes, streaming real-time data to the patient’s compatible device and the CCN Health platform.
See and Act on Data
Patients and clinicians view trends, set customizable high/low alerts, and make informed treatment decisions based on continuous data.
Live Data
Continuous Glucose Stream
Every five minutes, the Dexcom sensor captures a new glucose reading and streams it to the CCN Health platform. Clinicians see real-time trends, time-in-range analytics, and predictive alerts without waiting for a patient office visit.
- Readings every 5 minutes — no fingersticks
- Customizable high/low glucose alerts
- Trend arrows show where levels are heading
- 8.2% MARD — industry-leading accuracy

Why Dexcom
Key Benefits
Continuous glucose data that transforms diabetes care for patients and providers.
No Fingersticks
Eliminate painful fingerstick tests. The sensor continuously measures glucose levels through a tiny filament just beneath the skin. Patients can check their levels with a glance at their phone or watch.
Real-Time Insights
Glucose readings every five minutes with trend arrows showing where levels are heading. Customizable alerts warn of highs and lows before they become critical — day or night.

FAQ
Frequently Asked Questions
Common questions about Dexcom CGM for RPM programs.
Yes. Dexcom continuous glucose monitors are FDA-cleared devices that qualify for RPM billing under CPT 99454. Glucose readings are captured every 5 minutes and transmitted to the CCN Health platform for clinical review.
Dexcom sensors transmit glucose readings to the patient's smartphone app, which syncs with the Dexcom cloud. CCN Health pulls data from the Dexcom API, providing clinical staff with real-time glucose trends, time-in-range metrics, and alert notifications.
Dexcom provides 288 readings per day (every 5 minutes) from a sensor worn for 10-15 days, versus 1-4 daily finger-stick readings with a traditional meter. CGM reveals glucose patterns, overnight trends, and postprandial spikes that finger sticks miss.
Type 1 diabetes, Type 2 diabetes on insulin therapy, gestational diabetes, and patients with hypoglycemic unawareness benefit most. The continuous data stream enables precise medication titration and early detection of dangerous glucose excursions.
Yes. Dexcom CGMs require a compatible smartphone for data relay. This differs from cellular RPM devices that transmit independently. For patients without smartphones, CCN Health offers standalone cellular glucose meters as an alternative.
