Abbott makes two CGM devices under different brand names at very different price points — the prescription FreeStyle Libre 3 ($130/month) and the OTC Abbott Lingo ($89/month). Both use the same core sensor technology. This guide covers every pricing option in 2026.

FreeStyle Libre 3: ~$130/month retail (prescription required). Abbott Lingo: ~$89/month (OTC, no prescription). Both use Abbott's 14-day sensor. FreeStyle Libre 3's published pivotal-trial MARD is 7.8%; Lingo's FDA submission reports a 8.1–10.7% MARD range rather than a single figure.
| Device | Price | Prescription | Sensor | MARD |
|---|---|---|---|---|
| Abbott Lingo | ~$89/month | No (OTC) | 14 days | 8.1–10.7% |
| FreeStyle Libre 3 | ~$130/month retail | Yes | 14 days | 7.8% |
The FreeStyle Libre 3 retails for approximately $130/month without insurance — significantly cheaper than the Dexcom G7 ($350/month). It requires a prescription and is cleared for adults and children with diabetes.
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 savings programs: Abbott offers the myFreeStyle program with savings cards for eligible patients. Check freestylelibre.us for current eligibility and savings amounts.
The newer Libre 3 Plus (15-day wear) carries a higher cash price: published pharmacy averages run about $240 per two-sensor month as of July 2026, with pharmacy discount coupons (SingleCare/GoodRx-class) bringing it down to roughly $162 at participating pharmacies. Cash prices vary by pharmacy and change frequently — verify before filling.
The biggest lever: Abbott's copay program. Eligible commercially-insured and uninsured patients pay no more than $75 per two sensors through Abbott's savings program (per freestyle.abbott, July 2026 — eligibility terms apply). If you're paying cash for any Libre sensor without checking this program first, you're likely overpaying. Our CGM cost without insurance hub compares every device's cash route.
Abbott Lingo costs approximately $89/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 $89/month, Lingo is the cheapest CGM available without a prescription (FDA-reported range: 8.1–10.7% MARD). Dexcom Stelo's published range (7.3–9.1% MARD) is lower. Insurance does not typically cover Lingo as it is an OTC wellness product.
| Device | Monthly cost | Prescription | Insurance coverage | MARD |
|---|---|---|---|---|
| Abbott Lingo | ~$89 | No | Unlikely | 8.1–10.7% |
| Dexcom Stelo | ~$99 | No | Unlikely | 7.3–9.1% |
| FreeStyle Libre 3 | ~$130 | Yes | Often covered | 7.8% |
| Dexcom G7 | ~$350 | Yes | Often covered | 8.2% |
