Best FSA Coverage Stelo CGM Alternatives (2026)
Dexcom's Stelo, launched in August 2024 as the first FDA-cleared over-the-counter glucose sensor, costs $99 for a 30-day pack. While marketed as HSA and FSA eligible, its specific user criteria and out-of-pocket cost make it just one option. For W2 employees, the self-employed, and families using HDHPs, finding the best FSA coverage Stelo CGM alternative involves balancing cost, eligibility, and medical need. This guide compares other CGMs and monitoring strategies you can buy with your 2026 health FSA, which has a $3,400 contribution limit.
Why Consider Alternatives
Users explore Stelo CGM alternatives primarily due to cost, as the $89-$99 monthly outlay adds up quickly. Others find Stelo's lack of real-time hypoglycemia alerts or its non-insulin user criteria doesn't fit their health needs. There's also administrative friction; while Stelo is OTC and marketed as FSA eligible, individual plan substantiation rules can create reimbursement hurdles.

Pro Tips
Before buying any CGM with FSA funds, call your FSA administrator or check your plan's online eligible items list. Ask specifically if the product code for Stelo or its alternatives is pre-approved to avoid reimbursement delays.
If you have a prescription for a CGM, submit a claim for reimbursement under your health FSA instead of using a debit card. This creates a paper trail and can help if the IRS ever questions the expense.
Consider the total annual cost. A $99 monthly Stelo subscription uses about $1,188 of your $3,400 FSA. Compare this to a prescription CGM's copay after insurance; you might save FSA funds for other eligible expenses.
Set a calendar reminder for open enrollment to adjust your FSA contribution based on expected CGM costs. If you start a CGM mid-year, you can only use funds already contributed up to that point.
For mixed dental/vision and general medical needs, see if your employer offers a Limited-Purpose FSA (LPFSA) paired with an HSA. The 2026 LPFSA limit is $3,400 and can cover eligible dental and vision expenses, freeing up HSA funds for CGMs.
Frequently Asked Questions
Is Dexcom Stelo definitely FSA and HSA eligible?
Dexcom markets Stelo as a qualified medical expense for FSA and HSA purchase. However, actual reimbursement depends on your specific plan administrator's rules and your ability to provide a detailed receipt. Some administrators may require additional documentation, even for this OTC product. Always check with your plan before purchasing to confirm you can get reimbursed.
What are the main reasons to look for a Stelo CGM alternative?
You might seek alternatives if you use insulin or experience hypoglycemia, as Stelo is not intended for those users. Cost is another factor; at roughly $100 per month out-of-pocket, other options might be more affordable or covered by insurance. You may also need different features, like real-time alerts or integration with an insulin pump, which Stelo does not provide.
Can I use my FSA for prescription continuous glucose monitors?
Yes, prescription CGMs like the Dexcom G7 or Abbott FreeStyle Libre systems are qualified medical expenses. Using FSA funds for them often requires a prescription and a Letter of Medical Necessity from your doctor for reimbursement. If you have insurance, your plan may cover a portion, reducing your out-of-pocket FSA cost significantly compared to an OTC purchase like Stelo.
What is the 2026 FSA contribution limit and carryover amount?
For 2026, the health FSA contribution limit is $3,400 per employee, a $100 increase from 2025. The maximum amount you can carry over from 2026 into 2027 is $680, assuming your employer's plan allows carryovers. These limits are set by the IRS and apply to most employer-sponsored health FSAs.
Are there other over-the-counter CGMs besides Stelo?
Yes. As of late 2024, Abbott's Lingo is another notable OTC glucose biosensor available without a prescription. Like Stelo, it is also described as FSA-eligible. The market for OTC CGMs is new and may expand, so it is wise to compare the sensor wear time, app features, and pricing between Stelo and Lingo before using FSA funds.
What receipts do I need for FSA reimbursement for a CGM?
You typically need a detailed receipt showing the date of purchase, merchant name, a clear description of the item (e.g., 'Dexcom Stelo Glucose Sensor 30-day pack'), and the amount paid. For subscription purchases, keep the initial order confirmation and monthly statements. For prescription CGMs, your plan may also require the prescription and an itemized invoice from the medical supplier.
Who is the Dexcom Stelo actually designed for?
Stelo is designed for adults 18 and older who are not using insulin and do not experience hypoglycemia. Health experts state it is appropriate for adults with prediabetes, type 2 diabetes not meeting prescription-CGM criteria, or even individuals without diabetes who want to track glucose responses to diet and exercise.
