Dexcom Stelo: Who It Is For, Price and Coverage

The facts at a glance

Each fact is from the maker’s own page, checked Dexcom Stelo: 2026-11-01. “Not stated” means the maker’s page did not say. Prices and coverage change; confirm with the maker.

Who it is cleared for

Adults 18 and older who are not on insulin. Dexcom says not to use it if you have problematic hypoglycemia. A CGM is cleared by the FDA for specific uses, and the maker’s label is the final word. Over-the-counter sensors are built for people who do not use insulin. If you take insulin, a prescription system is the kind cleared for that.

Wear time and warm-up

Wear time: About 15 days. Warm-up: Not stated on Stelo's page. A warm-up is the period after you start a sensor when it does not yet show glucose readings. Start a sensor when you can wait that long, and keep a backup meter if your care team advises one.

Phone and app

Stelo says a compatible smartphone is required to pair a new sensor with an Apple Watch and points to a compatibility page for app details. We did not read minimum versions.

Insulin pump and AID compatibility

Not for people on insulin, so not used with pumps. Compatibility depends on the pump model and software, so check the pump maker’s page too.

Price

$89.00 per month on subscription (listed as down from $99.00). HSA/FSA eligible. A one-time purchase price was not shown.

Medicare

Stelo is sold over the counter. Medicare's CGM rules (LCD L33822) cover prescribed CGMs for insulin-treated people or those with problematic lows, and Stelo is not for people on insulin. We found no statement from Medicare or Dexcom that Part B pays for Stelo.

Medicare’s own rules are on Does Medicare cover a CGM?

More from the maker

• Stelo's footnote says 77.9% of sensors lasted the full 15 days, so roughly one in five may not.
• Dexcom says the device is not intended to be used to take medical action without talking with a healthcare professional.

What to do with the readings

A CGM report lets you work out a GMI and time in range, and you can keep notes in the private blood sugar log. Bring the report to your care team. See every device side by side in the CGM comparison.
