Details
Over-the-counter glucose biosensors such as Dexcom Stelo and Abbott Lingo are sold without a prescription. They can qualify when you use them mainly to monitor a condition such as diabetes or prediabetes under a doctor's care, because devices used in diagnosing and treating illness are medical expenses. Tracking glucose for general wellness, fitness, or curiosity does not qualify. Prescription CGMs such as Dexcom G7 and FreeStyle Libre are covered by the Blood Glucose Monitor decision.

Frequently Asked Questions
Is a Stelo or Lingo HSA-eligible?
Only when it is used mainly to diagnose, treat, or prevent a specific condition, such as diabetes or prediabetes your doctor is managing. Buying one to track glucose for general wellness does not qualify.
How is this different from a prescription CGM?
A prescription CGM such as Dexcom G7 or FreeStyle Libre is prescribed to manage a diagnosed condition and follows the Blood Glucose Monitor decision. An over-the-counter biosensor needs your own records showing its medical purpose.
What should I keep with the receipt?
Keep a physician's diagnosis or a letter of medical necessity that ties the monitor to your condition, along with proof of payment.
