Continuous Glucose Monitors (CGMs) are wearable devices that track your blood sugar levels throughout the day and night without finger pricks. A small sensor inserted under the skin measures glucose in interstitial fluid and transmits readings to a receiver or smartphone app every few minutes. CGMs show trends and patterns, alert you to highs and lows, and help you and your doctor make better treatment decisions. Popular CGMs include Dexcom and FreeStyle Libre. CGM coverage varies by insurance; Medicare covers CGMs for qualifying patients. Contact Specialty Medical Equipment to check your eligibility.
