Question 1

Is Dexcom Stelo officially HSA and FSA eligible?

Accepted Answer

Yes. Dexcom explicitly markets Stelo as eligible for use with Health Savings Accounts and Flexible Spending Accounts on its official product and provider pages. The company states it is a qualified medical expense. However, the final approval for reimbursement always depends on your specific plan administrator and the available balance in your account. You should verify with your administrator before purchasing.

Question 2

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

Accepted Answer

No. A major feature of the Stelo is its over-the-counter status. It received FDA clearance in 2024 and requires no prescription. Dexcom's provider materials also state no pre-authorization is needed. This simplifies the purchase process compared to prescription CGMs, making it a straightforward cash-pay item you can buy directly and seek reimbursement for, provided your plan allows it.

Question 3

What is the cost of Dexcom Stelo and can I use my HSA card?

Accepted Answer

At launch, consumer pricing was set at $99 for a 2-sensor, 30-day supply. A subscription option offers a 10% discount, bringing the cost to $89 per month. Dexcom also cited a potential price as low as $89.99 per 2-pack. Whether you can use your HSA debit card directly depends on your plan's rules for OTC medical devices. Some administrators allow direct card swipes at qualified retailers, while others require you to pay out-of-pocket and submit a receipt for reimbursement.

Question 4

Who is the Dexcom Stelo intended for?

Accepted Answer

Dexcom designed Stelo for adults 18 and older who are not on insulin. Its indication specifically excludes individuals with problematic hypoglycemia. The target user group includes people with prediabetes or type 2 diabetes who are not using insulin. If you use insulin, you likely need a prescription CGM. Ensuring you fall within the intended user group supports the argument that the expense is medically necessary for HSA/FSA purposes.

Question 5

What if my HSA/FSA plan administrator denies the Stelo purchase?

Accepted Answer

This is a valid concern. Even though Dexcom states it is eligible, individual plan administrators have the authority to set their own guidelines. If denied, your first step is to ask for the specific reason. You can then provide documentation from Dexcom's website that classifies Stelo as a qualified medical expense. If the denial stands, you may need to pay with after-tax dollars and keep the receipt in case IRS qualification guidelines change or for potential future appeals.

Question 6

How does Stelo's sensor wear time and reliability affect its value for HSA/FSA funds?

Accepted Answer

Each Stelo sensor is designed to last 15 days. A company study found 77.9% of sensors lasted the full 15 days, while about 20% may not last the full duration and roughly 10% may last less than 12 days. When using limited HSA/FSA funds, this reliability rate is a factor in cost-per-day value. A sensor that fails early might require a replacement purchase, so buying from a retailer with a good return policy is a smart financial move.

Question 7

Can I invest my HSA funds and still use them for Dexcom Stelo later?

Accepted Answer

Yes, this is a key HSA strategy. If your HSA provider like Fidelity or Lively offers investment options, you can invest a portion of your balance for growth. You can pay for Stelo out-of-pocket today, save the receipt, and reimburse yourself from the HSA years later. This allows your invested funds to grow tax-free while still covering the eligible expense, effectively making Stelo a tax-advantaged purchase that supports long-term retirement healthcare savings.

Question 8

Is Dexcom Stelo covered by health insurance?

Accepted Answer

At its launch in August 2024, Stelo was reported as not currently covered by health insurance plans. This fact makes HSA and FSA accounts the primary path for using tax-advantaged money to pay for it. For W2 employees with HDHPs, this highlights the value of contributing enough to your HSA to cover such eligible OTC healthcare products that fall outside standard insurance coverage.

Question 9

What makes Dexcom Stelo a qualified medical expense for HSA/FSA?

Accepted Answer

The IRS defines qualified medical expenses as costs for the diagnosis, cure, mitigation, treatment, or prevention of disease. Stelo is a glucose monitoring device for managing prediabetes and type 2 diabetes, which falls under 'mitigation' and 'treatment.' Its FDA clearance and OTC status for this specific medical purpose support its qualification. Dexcom's explicit marketing of it as HSA/FSA eligible reinforces this position.

Question 10

Can I buy Dexcom Stelo for a family member with my HSA?

Accepted Answer

Yes, you can use your HSA funds for qualified medical expenses for yourself, your spouse, and your tax dependents. If your spouse or dependent child meets the Stelo's intended user criteria (18+, not on insulin), purchasing it for them is an eligible expense. For FSAs, similar rules apply, but you should confirm dependent eligibility specifics with your plan.

Question 11

Does the IRS eligibility for CGMs like Stelo ever change?

Accepted Answer

Yes. Dexcom notes the IRS list of qualified medical expenses can change at any time. While glucose monitoring devices have a long history of eligibility, it is your responsibility to use funds for expenses that are qualified at the time of purchase. Checking the IRS Publication 502 annually or consulting a tax advisor before large purchases is a safe habit.

Question 12

Is there a difference between HSA and FSA eligibility for Stelo?

Accepted Answer

Typically, no. Both accounts follow the same IRS rules for qualified medical expenses. The practical difference lies in plan administration. Your specific FSA might have a different approval process or documentation requirement than your HSA. Some FSAs may have stricter lists of pre-approved items. Always check with each plan's administrator separately.

Question 13

What documentation do I need to keep for IRS audit proof?

Accepted Answer

Keep the itemized receipt showing the purchase of Dexcom Stelo, the date, and the amount. Also, save a copy of your plan statement showing the reimbursement or debit. It is wise to also keep a screenshot from Dexcom's website from around your purchase date stating it is HSA/FSA eligible. This package proves the expense was for a qualified medical device.

Question 14

What are the steps to buy Stelo with my HSA debit card?

Accepted Answer

First, confirm your card is activated for merchant category codes (MCC) for medical supplies. Second, verify the retailer (like a pharmacy or Dexcom's site) is coded correctly. Third, ensure your HSA has sufficient available cash (not invested funds) to cover the charge. At checkout, run the card as credit. If it's declined, pay another way and submit for reimbursement instead.

Question 15

How do I submit a receipt for HSA/FSA reimbursement?

Accepted Answer

Log into your HSA or FSA provider's online portal. Find the 'Submit Reimbursement' or 'Claims' section. You will need to upload a clear image of your receipt, enter the date of service (purchase date), the provider (store name), and the amount. For the expense type, select 'Medical Equipment' or 'Medical Supplies' and specify 'glucose monitor' in the description.

Question 16

How long does HSA/FSA reimbursement for Stelo typically take?

Accepted Answer

Processing times vary by administrator but often range from 3 to 10 business days after claim submission. Some providers offer direct deposit to your bank account, while others mail a check. Submitting a clean, legible receipt with all required information speeds up the process. Check your plan's website for their specific timeline.

Question 17

Can I buy the Stelo subscription with my HSA/FSA?

Accepted Answer

Yes, the monthly $89 subscription fee is an eligible recurring expense. You can set up automatic reimbursements if your plan allows it. Alternatively, pay the subscription with a personal card and submit the monthly charge as a claim. Keep each monthly receipt. Make sure your subscription agreement clearly states it is for the Dexcom Stelo device.

Question 18

What if the store receipt just says 'sensor' and not 'Dexcom Stelo'?

Accepted Answer

This is a common issue that can cause claim denial. Before leaving the store, ask the cashier to print a detailed receipt. If you have an online order, the email confirmation usually has details. If your receipt is vague, you may need to attach a copy of the product packaging or the online order summary that shows the product name to your reimbursement claim.

Question 19

Is Dexcom Stelo a good value for my HSA dollars compared to a prescription CGM?

Accepted Answer

It depends on your insurance. Prescription CGMs like Dexcom G7 can cost $0 per month with good insurance but often involve prior authorization, co-pays, and deductible requirements. Stelo, at roughly $45 per sensor, is a predictable cash cost. For someone with a high-deductible plan not yet met, or with insurance that doesn't cover CGMs, paying directly with HSA funds for Stelo can be simpler and more cost-effective.

Question 20

How does Stelo's $99 cost impact my HDHP deductible and out-of-pocket max?

Accepted Answer

Purchasing Stelo with your HSA does not count toward your health plan's deductible or out-of-pocket maximum. HSA funds are separate from insurance claims. You are paying directly for a medical expense outside your insurance plan. This is a key point of confusion: HSA purchases are independent, while payments applied to your deductible are processed through your health insurer.

Question 21

Can I deduct Stelo on my taxes if I don't use my HSA?

Accepted Answer

Potentially, yes. Medical expenses, including the cost of Stelo, are deductible on Schedule A if you itemize deductions and your total qualified medical expenses exceed 7.5% of your Adjusted Gross Income. This is a high bar, so most people find the immediate tax benefit of using HSA/FSA funds more advantageous than hoping for a year-end itemized deduction.

Question 22

Should I prioritize funding my HSA over other accounts to pay for devices like Stelo?

Accepted Answer

If you anticipate regular health expenses like Stelo, maximizing your HSA contributions is a smart move. HSA funds are triple tax-advantaged: tax-deductible going in, tax-free growth, and tax-free withdrawal for qualified expenses. This makes it one of the most efficient accounts for funding current and future healthcare needs, often prioritized above taxable investment accounts after capturing a 401(k) match.

Question 23

Are there any hidden costs with Stelo that my HSA can cover?

Accepted Answer

The primary ongoing cost is the sensor itself. The Stelo reader app is free. Your HSA cannot cover a smartphone used to run the app unless it is purchased specifically for medical monitoring and a doctor recommends it. Standard data plans for your phone are also not eligible. The eligible expense is strictly the sensor device.
