Question 1

Is the Stelo Glucose Biosensor definitely FSA and HSA eligible?

Accepted Answer

Yes, Dexcom explicitly states the Stelo Glucose Biosensor is a qualified medical expense eligible for FSA and HSA funds. This is because it is an FDA-cleared device used for diagnosing and managing glucose levels, which falls under the IRS Publication 502 definition. However, the final approval for reimbursement always rests with your specific plan administrator. They may have their own documentation requirements, so it's best to check with them before purchasing.

Question 2

What do I need to submit for FSA reimbursement for Stelo?

Accepted Answer

You typically need a detailed receipt that includes the date of purchase, the merchant name (Dexcom or the pharmacy), a clear item description like 'Stelo Glucose Sensor 2-pack', and the amount paid. Since Stelo is an OTC product, a prescription is not required for purchase. Some plan administrators might also ask for a Letter of Medical Necessity from your doctor, so confirming their specific rules upfront can prevent delays.

Question 3

How much does the Stelo Glucose Biosensor cost, and how does it fit into my FSA budget?

Accepted Answer

The Stelo starter pack costs $99 for a 30-day supply containing two sensors. The subscription model is $89 per month, which totals about $1,068 annually. With the 2026 health FSA contribution limit set at $3,400 per employee, an annual Stelo subscription would use approximately 31% of your total limit. This makes it a significant but manageable expense within a well-planned FSA budget, especially for those tracking glucose without insulin.

Question 4

Can I use my FSA for Stelo if I don't have diabetes?

Accepted Answer

Yes, you can. Stelo is approved for adults 18 and older who do not use insulin and do not have problematic hypoglycemia. This includes individuals with Type 2 diabetes, prediabetes, and non-diabetics who want to track their glucose responses to food and lifestyle. Since it is an FDA-cleared diagnostic device, its use for personal health monitoring qualifies as a medical expense under IRS rules, regardless of a formal diabetes diagnosis.

Question 5

Will my health insurance cover the Stelo Glucose Biosensor?

Accepted Answer

No, Stelo is not covered by traditional health insurance plans. It is marketed and sold as an over-the-counter product directly to consumers. This makes FSA and HSA funds the primary tax-advantaged payment methods available for purchasing it. You cannot submit a claim to your medical insurance for reimbursement, so planning to use your FSA or HSA is the correct financial strategy.

Question 6

What happens if my FSA plan administrator denies my Stelo reimbursement?

Accepted Answer

If your claim is denied, your first step should be to contact your plan administrator for a specific reason. Often, denials happen due to missing information on the receipt or a lack of prior confirmation that the expense is eligible. You can appeal the decision by providing Dexcom's marketing materials that state it's a qualified medical expense and referencing IRS Publication 502. Keeping clear records and pre-approving expenses when possible minimizes this risk.

Question 7

How does the Stelo's eligibility compare to a traditional CGM like the Dexcom G7?

Accepted Answer

Both devices are eligible as qualified medical expenses. The key difference is access and insurance. The Dexcom G7 requires a prescription and is often covered by insurance for individuals with diabetes using insulin. Stelo is available over-the-counter without a prescription but is not covered by insurance. For FSA/HSA users, the reimbursement process is similar, but Stelo offers a lower barrier to entry for those not using insulin, though it comes with a full out-of-pocket cost.

Question 8

What IRS rule makes the Stelo Glucose Biosensor FSA eligible?

Accepted Answer

Eligibility is grounded in IRS Publication 502, which defines qualified medical expenses to include devices and equipment used for the diagnosis, cure, mitigation, treatment, or prevention of disease. As an FDA-cleared device for monitoring glucose levels, the Stelo biosensor fits this definition for diagnosing and managing a health condition, making it an allowable expense.

Question 9

Does the 'over-the-counter' status affect FSA eligibility for Stelo?

Accepted Answer

No, the over-the-counter status does not affect eligibility. Since the passage of the CARES Act, many OTC medical products and devices no longer require a prescription to be FSA/HSA eligible. Stelo's FDA clearance as a medical device is the key factor, not its point-of-sale classification.

Question 10

Are there any income or health status restrictions for using FSA funds on Stelo?

Accepted Answer

There are no income restrictions. Your eligibility to contribute to an FSA is based on your employer offering the plan. For using the funds, the only restriction is that the expense must be qualified. Your personal health status or reason for using Stelo (e.g., diabetes management vs. general wellness) does not impact the eligibility of the device itself under IRS rules.

Question 11

If my spouse or dependent uses the Stelo, can I use my FSA?

Accepted Answer

Yes, you can use your FSA funds to pay for qualified medical expenses for yourself, your spouse, and your tax dependents. If your spouse or a dependent child uses the Stelo Glucose Biosensor, the cost is eligible for reimbursement from your FSA, as long as you can provide the required receipt documentation.

Question 12

How does the 'final approval' from my plan administrator work?

Accepted Answer

While the IRS sets broad categories, your FSA plan administrator has the final say on what they will reimburse. They interpret the rules and manage the plan's funds. They may require specific documentation beyond a basic receipt. Always check your plan's Summary Plan Description or contact them directly to confirm their process for a device like Stelo before you rely on reimbursement.

Question 13

Can I use FSA funds for the Stelo app or subscription service fee?

Accepted Answer

Yes, the associated software and service fees required to operate a medical device are typically considered part of the cost of that device. The $89 monthly subscription fee for Stelo, which includes sensor data access and analysis through the app, should be eligible as part of the overall expense for the glucose monitoring system. Bundle this on your receipt if possible.

Question 14

What is the 2026 FSA contribution limit and carryover amount?

Accepted Answer

For 2026, the health FSA contribution limit is $3,400 per employee. Plans that allow a carryover from the previous year can permit a maximum of $680 to roll over. This means your total potential spending power for 2026 could be $4,080 if you maxed out your 2025 contribution and carried over the full $680.

Question 15

Is the full annual cost of a Stelo subscription ($1,068) deductible from my taxes?

Accepted Answer

No, FSA contributions are made with pre-tax dollars through payroll deduction, so you get the tax benefit upfront. The $1,068 is not an additional tax deduction. You avoid paying income and payroll taxes on the money you contribute to your FSA, which effectively reduces the net cost of the Stelo by your marginal tax rate.

Question 16

What happens if I leave my job and have an FSA debit card charge for Stelo pending?

Accepted Answer

If you leave your job, you typically lose access to your FSA funds unless you elect COBRA continuation for the FSA. Any charges made before your termination date for eligible expenses are valid. However, if you make a purchase after your termination, you may be personally liable for the charge. It's best to use all planned FSA funds for items like Stelo before your last day.

Question 17

Can I use both FSA and HSA money to pay for Stelo?

Accepted Answer

You generally cannot contribute to both a general purpose FSA and an HSA in the same year. However, if you have a Limited Purpose FSA (for dental/vision only) with an HSA, you cannot use the LPFSA for Stelo. If you only have an HSA, you can use those funds. You cannot 'double-dip' by reimbursing the same Stelo purchase from both an FSA and an HSA.

Question 18

How should I budget for Stelo within my annual FSA election?

Accepted Answer

During your employer's open enrollment, estimate your total qualified medical expenses for the year. If you plan a Stelo subscription ($1,068), add other expected costs like copays, dental work, and eligible OTC items. Ensure your total election does not exceed the $3,400 limit. If you have funds left from the prior year ($680 max carryover), you can factor that in to lower your new election.

Question 19

What if the cost of Stelo increases after I set my FSA election?

Accepted Answer

Your FSA election is generally locked for the plan year unless you have a qualifying life event (like marriage or birth of a child). A price increase in a product is not a qualifying event. This is why it's wise to build a buffer into your FSA election for unexpected medical costs or price changes on planned purchases like a yearly sensor supply.

Question 20

Where can I buy the Stelo Glucose Biosensor with FSA funds?

Accepted Answer

You can purchase Stelo directly from the official Stelo website (Stelo.com) or from participating pharmacies and retailers. When buying online, ensure the checkout process allows you to get a detailed receipt. Some major pharmacy chains with FSA stores online are also likely to carry it, which can simplify the purchase if you use your FSA debit card there.

Question 21

What specific details must be on my receipt for FSA reimbursement?

Accepted Answer

Your receipt must clearly show: 1) The date of purchase. 2) The name and address of the seller (e.g., Dexcom, Inc.). 3) A description that matches a qualified expense, such as 'Stelo Glucose Biosensor System' or 'Continuous Glucose Monitor Sensor'. 4) The item price and total amount paid. A bank statement alone is usually insufficient.

Question 22

How long does FSA reimbursement for a Stelo purchase typically take?

Accepted Answer

Reimbursement time varies by plan administrator. If you submit a complete claim with a proper receipt, many providers process payments within 7 to 14 business days via direct deposit or check. Using an FSA debit card for the purchase is instant, but you should still save your receipt in case your plan requires post-purchase verification or audit.

Question 23

What is a Letter of Medical Necessity, and do I need one for Stelo?

Accepted Answer

A Letter of Medical Necessity (LMN) is a document from your doctor stating that a device or service is required to treat a medical condition. While not always required for Stelo because it's OTC, some conservative FSA administrators may request it. Having one prepared can prevent delays, especially if your use case is for prediabetes or metabolic health tracking.

Question 24

Can I be audited for my Stelo FSA reimbursement?

Accepted Answer

Yes, the IRS can audit any tax-related claim, and your FSA plan administrator may perform random audits. This is why keeping meticulous records for at least 3 years is critical. Save your detailed receipt, any LMN, and a copy of your reimbursement approval. The fear of an audit is a common pain point, but proper documentation makes the process simple.

Question 25

What's the difference in process between FSA and HSA reimbursement for Stelo?

Accepted Answer

The eligibility is the same. The process differs: With an FSA, you often file a claim with your employer's third-party administrator after purchase. With an HSA, you typically manage the account yourself (e.g., at Fidelity). You can pay directly with an HSA debit card or pay out-of-pocket and later reimburse yourself from the HSA account online, uploading the same receipt.

Question 26

Who is the Stelo Glucose Biosensor designed for?

Accepted Answer

Stelo is designed for adults 18 and over who do not use insulin and do not experience problematic hypoglycemia. This includes the large group of people with Type 2 diabetes managing their condition without insulin, individuals with prediabetes, and non-diabetics interested in understanding how diet and exercise affect their glucose levels for general wellness.

Question 27

How is Stelo different from a regular blood glucose meter and test strips?

Accepted Answer

Traditional meters require finger-prick blood samples at specific moments. Stelo is a continuous glucose monitor (CGM) with a sensor worn on the arm that automatically reads glucose levels from interstitial fluid every 15 minutes, providing real-time trends and patterns. Both are FSA/HSA eligible, but Stelo offers constant data without daily finger sticks.

Question 28

Should I choose an FSA or HSA to pay for Stelo?

Accepted Answer

This depends on your health plan. You need a High Deductible Health Plan to qualify for an HSA. HSAs have higher contribution limits, funds roll over forever, and can be invested. FSAs are use-it-or-lose-it (with limited carryover) but are available with many non-HDHP plans. If you have both options, an HSA is often more flexible for long-term savings, even for expenses like Stelo.

Question 29

Can I use my Dependent Care FSA for Stelo?

Accepted Answer

No, a Dependent Care FSA is strictly for childcare or adult dependent care expenses so that you can work. It cannot be used for medical devices or healthcare expenses like the Stelo Glucose Biosensor. You must have a Health Care FSA or an HSA to cover this type of purchase.

Question 30

What if my doctor recommends Stelo but I have an FSA that requires a prescription?

Accepted Answer

Even though Stelo is OTC, if your FSA plan's internal rules require a prescription for all medical devices, get one from your doctor. Have them write a prescription for 'continuous glucose monitoring sensor, Stelo by Dexcom.' Submit this with your receipt. This satisfies the plan's requirement while aligning with the product's marketing and IRS rules.

Question 31

Are there any other new OTC health monitors that are FSA eligible like Stelo?

Accepted Answer

Stelo is a pioneer as the first OTC CGM. Other OTC health tech, like certain smartwatches with FDA-cleared ECG features, may also be eligible if used for a diagnosed condition. The landscape is evolving. The rule of thumb: if a device is FDA-cleared/approved for a medical purpose and not merely general wellness, it has a strong case for FSA/HSA eligibility.
