With insurance: FreeStyle Libre 3 is commonly covered by Medicare Part B and most private insurance plans for qualifying patients with diabetes. Out-of-pocket costs after insurance typically range from $0–40/month depending on your plan.

Abbott Lingo costs approximately $49/month for two 14-day sensors and requires no prescription. It uses virtually identical sensor technology to the FreeStyle Libre 3 but is marketed as a wellness product for people without diabetes.
At $49/month, Lingo is the cheapest CGM available without a prescription and has the best published accuracy of any OTC device (7.8% MARD). Insurance does not typically cover Lingo as it is an OTC wellness product.
| Device | Monthly cost | Prescription | Insurance coverage | MARD |
|---|---|---|---|---|
| Abbott Lingo | ~$49 | No | Unlikely | 7.8% |
| Dexcom Stelo | ~$99 | No | Unlikely | 8.7% |
| FreeStyle Libre 3 | ~$130 | Yes | Often covered | 7.9% |
| Dexcom G7 | ~$350 | Yes | Often covered | 8.2% |
