Dexcom Stelo HSA FSA Eligibility Tips (2026)

Before spending any money, contact your HSA or FSA provider directly. Ask if they currently reimburse for the Dexcom Stelo as an OTC glucose monitor. Policies can vary even though the product is marketed as eligible.

The IRS may request proof that your HSA distribution was for a qualified medical expense. Your receipt is primary evidence. Ensure it shows the date, merchant name, product name 'Dexcom Stelo,' and amount paid.

Many HSA/FSA administrators handle recurring subscriptions differently than one time purchases. Some may not allow automatic debit card charges for subscriptions. You may need to pay manually each month and submit for reimbursement.

For an expense to be qualified, it must be for medical care. Having a documented health condition that Stelo addresses strengthens your position. This is especially important for those with prediabetes without a formal insulin dependent diagnosis.

HSAs are individually owned and funds roll over forever. FSAs are often employer sponsored with a use it or lose it rule (with possible grace period or carryover). This affects when you should buy Stelo to avoid losing FSA money.

HSA distributions are reported on Form 8889. Non qualified distributions are taxable and subject to a 20 percent penalty. Properly documenting your Stelo purchase ensures you report it correctly as a qualified distribution on line 15 of Form 8889.

Stelo's OTC and HSA eligible status sets a precedent. As more health tech devices gain OTC FDA clearance, the process you learn for Stelo can be applied. Always start with the manufacturer's marketing and then verify with your plan administrator.
