Dexcom G7 without insurance: price set by your pharmacy or plan. Dexcom Stelo (OTC) without insurance: price set by Dexcom. No prescription needed for Stelo. G7 requires a prescription but may be covered by insurance for qualifying patients.
| Device | Price without insurance | Prescription | Sensor life | MARD |
|---|---|---|---|---|
| Dexcom G7 | Check price retail | Yes (required) | Up to 10 days + 12-hour grace | 8.2% adult arm study |
| Dexcom Stelo | Check price | No (OTC) | 15 days | 7.3–9.1% (historical adults, by wear period) |
Check Dexcom and your pharmacy for current model information, prescription requirements and prices. A device's prescription status is not an accuracy ranking.
Ways to reduce G7 cost without insurance:
Dexcom Cares program: Dexcom offers a patient savings program for uninsured or underinsured patients. Eligibility is income-based. Apply at dexcom.com.
GoodRx: GoodRx discount cards can reduce G7 cost at participating pharmacies. Savings vary by location and pharmacy — check goodrx.com for current pricing in your area.
Ask your plan administrator whether the specific purchase qualifies for HSA/FSA reimbursement. FDA clearance and OTC availability alone do not establish eligibility.
The Dexcom Stelo price is set by Dexcom (see dexcom.com/stelo) and it requires no prescription. It is the OTC version of Dexcom's CGM technology, cleared for people aged 2 years and older (children under adult supervision) who do not use insulin. Check the selected offer’s sensor quantity and replacement terms. Up to 15-day labeled wear per sensor does not guarantee a full calendar month of continuous readings.
Compare the current Stelo and G7 supplier prices. Stelo is available at major pharmacies and online retailers without a doctor visit. Check with your insurer whether your plan covers the device.
| Device | Monthly cost | Prescription | Notes |
|---|---|---|---|
| Abbott Lingo | Check price | No | OTC CGM: study-specific MARD figures; separate studies do not establish clinical accuracy superiority |
| Dexcom Stelo | Check price | No | Dexcom platform, Clarity integration, 15-day sensor |
| FreeStyle Libre 3 | Check price | Yes | Manufacturer-reported accuracy from a separate study. Cost with insurance depends on your plan |
| Dexcom G7 | Check price | Yes | Check current manufacturer specifications; no independently established quality ranking is presented here. |
If you do not have insulin-treated diabetes and want to try CGM monitoring: consider Dexcom Stelo or Abbott Lingo. Both are OTC, require no prescription, and use similar sensor technology to the G7.
Coverage depends on the exact device, plan, documentation and supplier. Medicare requires all applicable criteria, including diabetes, a prescription, training, FDA-consistent use, required visits and insulin treatment or documented problematic hypoglycemia. Ask your insurer and prescriber about your situation.
