Dexcom CGM Cost: G7, G7 15-Day, and Stelo Pricing
Dexcom G7 and G7 15-Day Pricing
The Dexcom G7 and G7 15-Day share the same pricing structure: $20 to $40 per month with commercial insurance, and $250 to $350 per month without insurance. Medicare covers both devices with a typical patient copay of $20 to $50 per month. The G7 15-Day may offer slightly lower per-month costs over time because patients use 2 sensors per month instead of 3 (for the 10-day G7), reducing the total number of sensors purchased annually from approximately 37 to 25. This translates to an estimated $800 to $1,200 annual savings at uninsured retail pricing.

Dexcom Stelo OTC Pricing
The Dexcom Stelo is an over-the-counter product priced at $49 to $99 per month, purchased directly by consumers without insurance involvement. Each month includes 2 sensors (15 days each). The Stelo cannot be covered by insurance or Medicare because it is classified as a consumer wellness device, not a prescription medical device. Dexcom offers subscription pricing on its website with multi-month commitments that may reduce the per-month cost.
Dexcom Savings Programs
The Dexcom Savings Card is available to commercially insured patients and can reduce G7 or G7 15-Day copays by up to $200 per month. This program is not available to patients with Medicare, Medicaid, or other government insurance. Dexcom also maintains a patient assistance program for uninsured or underinsured patients who meet income eligibility criteria.

Dexcom G7 vs G7 15-Day: Cost Difference
The Dexcom G7 15-Day sensor costs approximately the same per-sensor as the standard G7, but you need fewer sensors per year — 24 sensors (15-day wear) versus 36 sensors (10-day wear). This reduces annual sensor consumption by 33% and translates to $800-1,200 less per year without insurance. With insurance, the copay difference is smaller because most plans charge per prescription fill (typically a 90-day supply) rather than per individual sensor. If your insurer covers the G7 15-Day, it is almost always the more economical choice.
