Original Libre 3 and Lingo each have up to 14-day wear, but are distinct devices. Original Libre 3 has 7.8% MARD for ages ≥6 versus YSI in Alva 2023. Lingo’s six selected bin values in FDA K233655 range from 8.1% to 10.7% using Libre 2 data; this is not overall MARD or a cross-study ranking. Check current prices with the manufacturer or pharmacy.
| Device | Price | Prescription | Sensor | MARD |
|---|---|---|---|---|
| Abbott Lingo | Check price | No (OTC) | 14 days | 8.1–10.7% (by glucose range) |
| FreeStyle Libre 3 | Check price retail | Yes | 14 days | 7.8% |
The FreeStyle Libre 3 cash price depends on your pharmacy — ask for today's price. It requires a prescription and is cleared for adults and children with diabetes.
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.
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) is priced by the pharmacy; cash prices vary by pharmacy, can be lowered with discount cards at some pharmacies, and change frequently — verify before filling.
Abbott’s savings program. Eligible commercially-insured and uninsured patients can reduce their cost through Abbott's savings program (see freestyle.abbott for current terms — eligibility applies). Check whether the program applies to your model and circumstances before comparing the final purchase cost. Our CGM cost without insurance hub compares every device's cash route.
Abbott Lingo is sold as 14-day sensors, requires no prescription, and is priced by Abbott (see hellolingo.com). Its sensor is based on the FreeStyle Libre 2 (FDA K233655) and it is FDA-cleared for adults aged 18 and older who do not use insulin (including people without diabetes).
Lingo is available without a prescription (FDA-reported range: 8.1–10.7% MARD (by glucose range)). Dexcom Stelo's published range (7.3–9.1% MARD (by wear period)) comes from a separate study and is not directly comparable. Check with your insurer whether your plan covers the device.
| Device | Monthly cost | Prescription | Insurance coverage | MARD |
|---|---|---|---|---|
| Abbott Lingo | Check price | No | Unlikely | 8.1–10.7% (by glucose range) |
| Dexcom Stelo | Check price | No | Unlikely | 7.3–9.1% (historical adults, by wear period) |
| FreeStyle Libre 3 | Check price | Yes | Often covered | 7.8% |
| Dexcom G7 | Check price | Yes | Often covered | 8.2% |
