Stelo and Lingo are the two OTC devices covered here, not an exhaustive FDA clearance list. Compare their model-specific instructions, packs and current manufacturer plans.

What you pay for a prescription CGM depends on your insurance coverage, so compare your own out-of-pocket prices with OTC options in the cost calculator. If you have a qualifying diagnosis and insurance coverage, what you pay out of pocket for a prescription CGM depends on your plan; compare it with OTC options in the cost calculator.
Prescription CGM pricing — before and after insurance
Compare the exact prescription CGM’s supplier price and your plan’s approved coverage and cost sharing. Prescription status alone does not establish a higher or lower purchase cost.
FreeStyle Libre 3 — prescription option
Price set by Abbott and your pharmacy or plan. 14-day sensor, 7.8% MARD, real-time streaming. With insurance, out-of-pocket cost can be much lower depending on your plan. Read full review →
Dexcom G7 — check current manufacturer information
Price is set by Dexcom and your pharmacy or plan. Published MARD is study-specific and does not establish superior performance in low glucose. Check current prices and coverage with the manufacturer, pharmacy or insurer.
CGM subscription platform pricing — app + sensor bundles
CGM subscription platforms bundle sensors with proprietary apps and, in some cases, coaching. They bundle sensors with an app or coaching layer, so compare the membership price with buying sensors directly.
Levels Health — app membership
Levels currently supplies Dexcom Stelo. It also supports bringing a Dexcom G7 or G7 15 Day through a connected Dexcom account; those readings reach Levels with about a one-hour delay. Use the Dexcom app for real-time readings. Service eligibility and device labeling are separate. Read full review → · Compare vs Nutrisense →
Nutrisense — sensors + RD coaching
Nutrisense currently lists Dexcom Stelo among its products. Coaching plans provide access to registered dietitians. Check the selected plan for sensor quantity, coaching and service eligibility; the device’s FDA indication does not determine eligibility for the service. Read full review →
7 days, 30 days, 90 days, or a full year — with or without prescription.
CGM cost with insurance — what to expect
Insurance coverage for CGMs depends entirely on your plan, your diagnosis, and whether the device is considered medically necessary. Here's how it typically breaks down:
Medicare coverage
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. With supplier assignment, Original Medicare cost sharing is 20% of the Medicare-approved amount after the Part B deductible; Medigap help depends on the policy.
Private insurance
Private insurance has its own device, indication, supplier and prior-authorization rules. Diagnosis or insulin use alone does not guarantee payment.
OTC devices and insurance
Ask your insurer whether your plan covers the specific OTC device before buying it; over-the-counter availability does not establish coverage. Some HSA/FSA accounts may cover them — check with your plan administrator.
Compare the actual approved benefit and cost sharing with the OTC price before buying. A diagnosis and prescription alone do not guarantee coverage or a lower bill.
What does a full year of CGM monitoring cost?
Annual cost depends on the manufacturer's current price, the sensor wear time and whether insurance applies. To estimate it: take the current monthly (or per-sensor) price from the manufacturer's site, multiply by the months you plan to monitor, and subtract any coverage. Prescription CGMs covered by insurance can cost far less than the same device bought at retail. Open the cost calculator →
Ways to use a CGM — by situation
No prescription, no insurance
Abbott Lingo is an over-the-counter CGM that needs no prescription — check Abbott for the current price. Built on the FreeStyle Libre 2 sensor (FDA K233655), simplified app, no Rx required.
Have a prescription, have insurance
Check whether your plan covers the exact prescribed Libre model and compare the approved cost sharing. No brand is guaranteed to be the cheapest covered option.
Want coaching alongside data
The CGM Program lists monthly Stelo glucose biosensors, 1:1 video-call coaching with registered dietitians or certified nutrition specialists (insurance-covered for most eligible members, self-pay options available), the Nutrisense app and a private community; an app-only membership exists for people with their own sensor. Check the provider for current plan inclusions and pricing.
