Question 1

Is the Dexcom Stelo CGM FSA eligible in 2026?

Accepted Answer

Yes, based on Dexcom's official statements. The company's FAQ for Stelo explicitly states the glucose biosensor is a qualified medical expense for purchase with FSA or HSA funds. This classification stems from its status as an FDA-cleared medical device for monitoring glucose levels. However, final approval for reimbursement rests with your specific FSA plan administrator.

Question 2

How much does Stelo cost and what are the subscription options?

Accepted Answer

Dexcom lists the Stelo starter pack at $99 for a one-time purchase, which includes two sensors for 30 days of monitoring. A subscription model is also available for $89 per month for the same two-sensor pack. This recurring cost makes it a predictable expense you can plan for with your FSA funds. Remember, the 2026 health FSA contribution limit is $3,400 per employee, so you can allocate a portion of your annual election to cover several months of Stelo use.

Question 3

Do I need a prescription or Letter of Medical Necessity to use FSA funds for Stelo?

Accepted Answer

Typically, no. Stelo is an over-the-counter product, so a prescription is not required to buy it. For FSA reimbursement, a detailed receipt showing the date, merchant, item description, and amount paid is usually the primary requirement. However, some conservative plan administrators might still ask for a doctor's note or prescription to substantiate the medical necessity, especially if their system is geared for prescription CGMs.

Question 4

Who is the Dexcom Stelo designed for?

Accepted Answer

Stelo is designed for adults 18 and older who do not use insulin and do not experience hypoglycemia. According to the Association of Diabetes Care & Education Specialists (ADCES), it is appropriate for adults with prediabetes, type 2 diabetes not using insulin, or even individuals without diabetes who want to track glucose responses to diet and exercise. This broad intended use supports its FSA eligibility as a general health monitoring tool, not solely a diabetes management device.

Question 5

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

Accepted Answer

Yes, you likely can. The IRS defines eligible medical expenses broadly as costs for the diagnosis, cure, mitigation, treatment, or prevention of disease. Since Stelo is an FDA-cleared device for glucose monitoring, using it to understand your metabolic health can fall under 'prevention' or 'diagnosis.' Your FSA provider may approve the expense based on the device's qualified status.

Question 6

What is the difference between Stelo and prescription CGMs like Dexcom G7 for FSA purposes?

Accepted Answer

The main difference is the purchase channel. Prescription CGMs like the G7 require a doctor's order and are often billed through insurance. Stelo is bought directly by the consumer over the counter. For your FSA, this changes the reimbursement paperwork. With Stelo, you pay out-of-pocket and submit a receipt. With a prescription CGM, you might submit an Explanation of Benefits (EOB) from your insurer.

Question 7

What proof do I need for FSA reimbursement of Stelo?

Accepted Answer

You need a detailed receipt that includes the date of purchase, the merchant's name (e.g., pharmacy or Dexcom website), a clear description of the item (e.g., 'Dexcom Stelo Glucose Sensor Starter Pack'), and the amount you paid. Since Stelo is OTC, this receipt is often sufficient. Some administrators may also accept a copy of your credit card statement showing the charge, but a receipt is better. Always check your plan's specific substantiation requirements.

Question 8

Can I use my FSA debit card to buy Stelo online?

Accepted Answer

Yes, if the online retailer is coded as a qualified medical merchant. Many major pharmacies and the Dexcom direct store should accept FSA debit cards. However, sometimes transactions are flagged for review. If your card is declined, you may need to pay with another method and submit for manual reimbursement. Keep the emailed receipt as your documentation. Contact your FSA card provider beforehand to confirm which merchants are pre-approved.

Question 9

What if my FSA plan administrator denies my Stelo claim?

Accepted Answer

First, ask for the specific reason for denial. Common reasons include missing information on the receipt or the administrator not recognizing the product. You can appeal by providing Dexcom's official material stating Stelo is a qualified medical expense. Reference IRS Publication 502, which lists blood sugar test kits as eligible. If denied again, you may need a Letter of Medical Necessity from your doctor, even though Stelo is OTC, to satisfy the administrator's rules.

Question 10

Are Stelo subscription payments FSA eligible?

Accepted Answer

Yes, recurring payments for a qualified medical device are eligible. Each monthly $89 charge can be reimbursed from your FSA. The best practice is to save every monthly receipt or invoice from Dexcom. For easier tracking, consider using your FSA debit card for the subscription if possible. Alternatively, set aside a portion of your annual FSA contribution to cover the expected yearly total of $1,068 for the subscription.

Question 11

How does Stelo's FSA eligibility compare to Abbott Lingo?

Accepted Answer

Both Dexcom Stelo and Abbott Lingo are over-the-counter CGMs marketed as FSA-eligible. The reimbursement process and eligibility are essentially the same for both devices. Your choice may come down to cost, sensor wear time, or app features. For FSA purposes, ensure you get a detailed receipt for whichever you buy. Market guides note these two as the main OTC CGM options, both qualifying as medical expenses under current interpretations.

Question 12

What is the health FSA contribution limit for 2026?

Accepted Answer

The health FSA contribution limit for 2026 is $3,400 per employee. This is an increase of $100 from the 2025 limit of $3,300. This is the maximum pre-tax salary you can elect to set aside for qualified medical expenses, including devices like the Stelo CGM. If your spouse also has an FSA through their employer, they have a separate $3,400 limit.

Question 13

How much can I carry over from my 2026 FSA to 2027?

Accepted Answer

If your employer's FSA plan allows the carryover option, you can carry over up to $680 of unused funds from 2026 into the 2027 plan year. This is a useful feature for planning Stelo purchases. For example, if you have $500 left in December 2026, you could use it in January 2027 to buy a Stelo starter pack or cover subscription costs, effectively extending your buying power.

Question 14

What is a Limited Purpose FSA (LPFSA) and can it pay for Stelo?

Accepted Answer

A Limited Purpose FSA is designed to work alongside an HSA and typically only covers dental and vision expenses initially. However, once you meet your health plan deductible, it often expands to cover all qualified medical expenses. The 2026 LPFSA contribution limit is also $3,400. Stelo, as a medical device, would be an eligible expense under an LPFSA after the deductible is met, but check your specific plan documents for confirmation.

Question 15

What is the dependent care FSA limit for 2026?

Accepted Answer

The dependent care FSA limit for 2026 is $7,500 per household ($3,750 if married filing separately). This account is separate from your health FSA and cannot be used for medical expenses like Stelo. It is only for eligible dependent care costs. Do not confuse these two accounts when budgeting for healthcare purchases.

Question 16

Should I increase my FSA contribution for 2026 to cover Stelo?

Accepted Answer

If you plan to use Stelo regularly, factor its cost into your FSA election. The subscription costs $1,068 per year ($89 x 12). Adding this to other expected expenses can help you decide if you need the full $3,400 limit. Remember the 'use-it-or-lose-it' rule; only elect what you will spend. The $680 carryover provides a buffer, but it's better to estimate accurately to maximize tax savings without forfeiting funds.

Question 17

Is Stelo covered by health insurance?

Accepted Answer

No, Dexcom states that Stelo is not covered by health insurance. It is designed as a direct-to-consumer, over-the-counter product. This is why using FSA or HSA funds is a primary method to pay for it with pre-tax dollars. You pay the full retail price out-of-pocket and then seek reimbursement from your FSA, effectively getting a discount equal to your tax rate.

Question 18

Can someone with type 2 diabetes using insulin get Stelo with FSA?

Accepted Answer

Dexcom specifies Stelo is for adults not using insulin. From a medical appropriateness standpoint, a person using insulin likely needs a prescription CGM with alerts. However, from a strict FSA eligibility perspective, the device itself is still a qualified medical expense. Your FSA might reimburse the purchase, but it is important to follow the intended use guidelines for your health and safety. Discuss with your doctor.

Question 19

How long does a Stelo sensor last and what's in the pack?

Accepted Answer

Each Stelo sensor is worn for 15 days. The standard pack contains two sensors, providing a total of 30 days of continuous glucose monitoring. The $99 one-time purchase or the $89 monthly subscription both provide this 2-sensor, 30-day supply. This predictable usage makes it easy to calculate annual FSA needs: four packs cover a quarter, twelve packs cover a full year.

Question 20

What makes Stelo different from a blood glucose meter for FSA?

Accepted Answer

Both are eligible FSA expenses. Traditional blood glucose meters and test strips are explicitly listed in IRS guidance. Stelo offers continuous data without fingersticks. For FSA purposes, the key is that both are for monitoring glucose. Stelo's higher upfront cost may require more planning within your annual FSA limit, but it provides a different type of data that may be valuable for understanding glucose trends.

Question 21

Can I buy Stelo for my spouse or child with my FSA?

Accepted Answer

Yes, you can use your FSA funds to pay for qualified medical expenses for your spouse and tax dependents. If your spouse or dependent child (under 19 or a full-time student under 24) meets the intended use criteria for Stelo, you can purchase it for them. The same receipt and reimbursement rules apply. Just ensure the expense is for a qualifying individual under your tax household.
