Continuous Glucose Monitoring (CGM) devices have become a cornerstone for diabetes management in the United States, offering real-time blood glucose data, enhanced safety, and convenience for millions with Type 1 and Type 2 diabetes. They also appeal to a broader audience seeking proactive health monitoring.

Costs and Insurance Coverage (2025)

Without insurance: Typical costs range from $89/month for over-the-counter sensors to $270/month for premium app-integrated plans. Annual costs generally fall between $1,200 and $3,600, though premium programs can be higher.

With insurance: Most plans (including Medicare) now cover mainline CGMs (Dexcom, FreeStyle Libre) for eligible patients with diabetes at little or no out-of-pocket cost. Coverage varies for non-diabetic or "wellness" users.

Discounts: GoodRx, manufacturer copay programs, and patient assistance are widely available for Dexcom, FreeStyle Libre, and others
