Question 1

Is Stelo officially FSA and HSA eligible?

Accepted Answer

Yes. Dexcom explicitly states the Stelo glucose biosensor is HSA and FSA eligible. The company classifies it as a qualified medical expense under IRS guidelines because it is an FDA-cleared device used for diagnosing and managing glucose levels. This classification is based on IRS Publication 502, which lists medical care expenses for the diagnosis, cure, mitigation, treatment, or prevention of disease. Since Stelo is designed for adults monitoring glucose, it meets this definition.

Question 2

Do I need a prescription to use FSA funds for Stelo?

Accepted Answer

A prescription is generally not required because Stelo is sold as an over-the-counter product directly to consumers. Dexcom markets it as an OTC device. However, some FSA or HSA plan administrators, especially those with strict interpretation rules, may request a Letter of Medical Necessity from your doctor. This letter should explain that the device is for managing a medical condition. To avoid reimbursement delays, check your plan's documentation requirements before purchasing.

Question 3

What documentation do I need for FSA reimbursement of Stelo?

Accepted Answer

You typically need a detailed receipt that includes several key pieces of information. The receipt must show the date of purchase, the merchant name (Dexcom), a clear item description such as 'Stelo Glucose Sensor 2-pack' or 'Stelo Starter Pack', and the exact amount paid. A generic credit card statement is usually insufficient. The receipt should prove the expense is for a medical device.

Question 4

Can I use my FSA for the Stelo monthly subscription?

Accepted Answer

This depends entirely on your FSA plan administrator's rules. Some administrators allow reimbursement for recurring subscription payments, treating each monthly charge as a separate eligible expense. Others only reimburse for one-time purchases. A common and safe method is to pay for the subscription with a personal credit card and then submit the monthly receipt from Dexcom for reimbursement from your FSA. Do not assume your FSA debit card will work for automatic monthly deductions from Dexcom.

Question 5

How much of my 2026 FSA will Stelo use?

Accepted Answer

The Stelo subscription costs $89 per month, which totals $1,068 for a full year. The 2026 annual health FSA contribution limit is $3,400 per employee. Therefore, a year of Stelo would use approximately 31% of your total available FSA funds. The one-time starter pack costs $99. If you have the maximum potential carryover of $680 from 2025, you could cover the first several months without impacting your new 2026 contributions.

Question 6

What are the 2026 HSA contribution limits if I use an HSA for Stelo?

Accepted Answer

For 2026, the HSA annual contribution limits are $4,300 for individuals with self-only High-Deductible Health Plan coverage and $8,550 for those with family HDHP coverage. These limits are higher than the FSA limit of $3,400. If you use an HSA, the $1,068 annual cost for Stelo would consume about 25% of the individual limit or 12.5% of the family limit.

Question 7

Who is the Stelo device intended for, according to experts?

Accepted Answer

The Association of Diabetes Care & Education Specialists states that Stelo is appropriate for adults aged 18 and older who are not using insulin and do not experience hypoglycemia (low blood sugar). This defines the target user as someone managing their glucose levels through diet, exercise, or non-insulin medications. If you fall into this category, the device is considered a legitimate medical expense.

Question 8

What makes a device like Stelo FSA eligible under IRS rules?

Accepted Answer

The IRS allows reimbursement for expenses for the diagnosis, cure, mitigation, treatment, or prevention of disease. Devices like the Stelo glucose biosensor, which is FDA-cleared for monitoring glucose levels, fall under 'diagnosis' and 'mitigation'. It provides data used to manage a health condition. The key is that the expense must be primarily for medical care. Cosmetic or general health items without a diagnosed condition are not eligible.

Question 9

Are all over-the-counter health devices FSA eligible?

Accepted Answer

No. The IRS changed rules with the CARES Act, reinstating eligibility for OTC medications and devices without a prescription, but the product must still be for medical care. A basic pedometer for general fitness is not eligible. A blood pressure monitor for managing hypertension is eligible. The distinction is the intended medical use for diagnosis or treatment of a specific condition. Stelo qualifies because it is a biosensor for glucose data, a key health metric.

Question 10

Could using FSA funds for Stelo trigger an IRS audit?

Accepted Answer

Any FSA reimbursement could be scrutinized in an audit, but using funds for an FDA-cleared medical device like Stelo is a strong, defensible position. The risk increases if you lack proper documentation or if the purchase seems inconsistent with your health profile. To protect yourself, keep the detailed receipt, a printout of Dexcom's product page stating its medical use, and if applicable, a Letter of Medical Necessity.

Question 11

Is there a difference between 'FSA eligible' and 'FSA approved'?

Accepted Answer

Yes, this is a critical nuance. 'FSA eligible' is a general classification based on IRS rules, which Dexcom claims for Stelo. 'FSA approved' means your specific employer's plan administrator has pre-vetted and confirmed they will reimburse for it. Many administrators have an online store or list of pre-approved items. Stelo may be eligible per the IRS but not on your plan's pre-approved list.

Question 12

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

Accepted Answer

First, request a clear explanation for the denial in writing. Common reasons include insufficient receipt detail or the administrator not recognizing the product as medical. Then, you can appeal. For your appeal, compile evidence: the detailed receipt, Dexcom's webpage stating Stelo is 'HSA/FSA eligible' and for 'glucose monitoring', the FDA clearance information, and a doctor's note if you have one. Submit this packet through your plan's formal appeals process.

Question 13

How does the $1,068 annual cost for Stelo compare to common FSA expenses?

Accepted Answer

At $1,068, Stelo is a major FSA expense. For comparison, a typical dental cleaning might cost $150-$300, a year's supply of prescription eyeglasses $200-$600, and a doctor's visit copay $30-$50. Using 31% of your $3,400 FSA on one device means you need to plan your other medical spending carefully. List all expected expenses: deductibles, copays, dental work, vision, and other eligible items like over-the-counter medications.

Question 14

What is the FSA carryover rule and how can it help with Stelo?

Accepted Answer

Many FSA plans allow you to carry over up to $680 of unused funds from one plan year to the next. This rollover amount is set by the IRS. If you had $680 carried over from 2025, you could apply it to your first Stelo purchase in 2026 without touching your new $3,400 annual contribution. This effectively gives you $4,080 to spend in early 2026. You could buy the $99 starter pack and several monthly subscriptions using just carryover funds, preserving your new contributions for other expenses.

Question 15

If I have a family HDHP, can I use my HSA for Stelo for my spouse?

Accepted Answer

Yes. If you have family HSA coverage, you can use your HSA funds for qualified medical expenses for yourself, your spouse, and your tax dependents, regardless of which family member's HDHP provides the coverage. So, if your spouse needs the Stelo device, purchasing it with HSA funds is perfectly allowable. The same documentation rules apply-keep the receipt showing the purchase.

Question 16

Should I max out my FSA if I plan to buy Stelo?

Accepted Answer

If you are certain you will purchase Stelo and have other predictable medical expenses, contributing the annual maximum of $3,400 to your FSA is a smart tax move. Your contributions are made pre-tax, reducing your taxable income. The $1,068 for Stelo, plus other costs, could easily use a large portion of that. However, remember the 'use-it-or-lose-it' rule (minus any carryover). Only max out your FSA if you are confident in your annual medical spending estimates.

Question 17

Can I use both FSA and HSA funds for Stelo in the same year?

Accepted Answer

Generally, no. You cannot be covered by a general-purpose FSA and contribute to an HSA in the same year. It creates a conflict in IRS rules. However, you can have a Limited Purpose FSA (for dental and vision only) alongside an HSA. In that setup, you could not use the Limited Purpose FSA for Stelo, as it is not a dental or vision expense. You would need to use your HSA funds. If you only have an FSA, you must use that.

Question 18

What is the safest way to pay for Stelo to ensure reimbursement?

Accepted Answer

The most straightforward method is to use a personal credit card or debit card for the purchase. Then, log into your FSA or HSA provider's website or app and submit a claim for reimbursement. Attach the detailed receipt from Dexcom. This method gives you clear proof of payment and a receipt you control. Avoid using your FSA debit card directly on the Dexcom site unless your plan's card system is known to work smoothly with merchant category codes for medical devices.

Question 19

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

Accepted Answer

Processing times vary by administrator but generally range from a few business days to two weeks after you submit a complete claim. Electronic submission with a clear, legible receipt is fastest. If your claim is flagged for manual review because Stelo is not on a pre-approved list, it could take longer. To avoid delays, ensure your receipt has all required details: date, merchant, description, and amount.

Question 20

Can I buy Stelo from a retailer like CVS and use my FSA?

Accepted Answer

Stelo is currently sold directly by Dexcom through their website, not through traditional retail pharmacies like CVS. Therefore, you must purchase it from Dexcom. If Dexcom ever expands to retail partners, the same rules would apply: you would need a receipt from that retailer clearly identifying the product as a Stelo glucose biosensor. A receipt that just says 'CVS' with a generic SKU number might not be sufficient. The receipt must link the purchase to the specific medical device.

Question 21

What should I do if my FSA debit card is declined on the Dexcom site?

Accepted Answer

Do not assume the decline means Stelo is ineligible. FSA debit cards are tied to merchant category codes (MCCs). The Dexcom online store might be coded under a general retail category instead of a medical supply category, triggering an automatic decline. Contact your FSA card provider's customer service. Explain you are trying to buy an FDA-cleared glucose monitor (Stelo) from the manufacturer's website. They may be able to pre-approve the transaction or provide a one-time override.

Question 22

How do I handle FSA reimbursement for the Stelo starter pack versus the subscription?

Accepted Answer

Treat them as separate expenses. For the one-time $99 starter pack, submit the single receipt you receive after purchase. For the $89 monthly subscription, you will receive a new receipt each month via email. You must submit each monthly receipt individually as a separate reimbursement claim, unless your plan has a special process for recurring expenses. Some plan portals let you set up a recurring claim, but you often still need to upload the new receipt each period.
