OTC CGM HSA FSA Eligibility Checklist (2026) | HSA Tracker
The Dexcom Stelo and Levels Lingo are FDA-cleared over-the-counter continuous glucose monitors. For 2026, these devices are qualified medical expenses for HSA and FSA funds without a prescription, thanks to the CARES Act. This otc cgm hsa fsa eligibility checklist helps you confirm your plan's rules, purchase correctly, and save 20 to 30 percent on annual costs. We cover the steps for W-2 employees, self-employed individuals, and families to use pre-tax dollars for metabolic health tracking.
Verify Your Account and Plan Eligibility
Before spending, confirm your specific FSA or HSA plan covers OTC CGMs. While the CARES Act allows it, plan administrators set final rules. This section ensures you start on solid ground for otc cgm hsa fsa eligibility.
Confirm you have an active HSA or Healthcare FSA for the 2026 plan year.
You must be enrolled in a qualifying High Deductible Health Plan (HDHP) for an HSA or have elected an FSA through your employer. Without an active account, you cannot use pre-tax funds.
Check your plan's summary of benefits for OTC medical device coverage.
The plan document or SPD will state if over-the-counter devices are eligible. Look for language referencing IRS Section 213(d) and the CARES Act amendments.
Contact your FSA/HSA administrator (e.g., Fidelity, Lively, HealthEquity) to ask about OTC CGM eligibility.
A direct confirmation from your provider gives you a paper trail. Ask, 'Are over-the-counter continuous glucose monitors like Dexcom Stelo a qualified expense without a prescription?'
Verify your current account balance and available funds for the purchase.
Know how much you can spend. For an FSA, remember the 2026 limit is $3,400. For an HSA, the 2026 limits are $4,300 (self) or $8,750 (family).
Understand your plan's reimbursement process and required documentation.
Some plans require itemized receipts with product description, date, amount, and merchant. Knowing this upfront speeds up reimbursement if you cannot use a debit card.
Determine if your FSA allows the $680 carryover or has a grace period.
If you are planning a late-year purchase, this affects your timing. You may be able to use current-year funds or have a short window after December 31.
Ensure your HSA is not linked to a Limited Purpose FSA that restricts spending.
A Limited Purpose FSA only covers dental and vision. If you have one, you cannot use it for a CGM. You must use your general HSA funds instead.
Research and Select Your OTC CGM Device
Choose the right device based on cost, features, and vendor compatibility with FSA/HSA payments. This step locks in your annual expense and potential tax savings.
Compare the Dexcom Stelo and Levels Lingo for features and sensor life.
Both are FDA-cleared for adults 18+ without insulin use. Stelo has a 15-day sensor, Lingo a 14-day sensor. Choose based on app functionality and personal data preferences.
Calculate the annual cost based on subscription or per-pack pricing.
Dexcom Stelo is $89/month ($1,068/year) or $84/month on a 3-month plan. Levels Lingo is $89/month or $249 for 3 months. Pick the model that fits your budget and usage.
Confirm the device is intended for managing a metabolic health condition.
IRS eligibility requires the expense be for the 'diagnosis, cure, mitigation, treatment, or prevention of disease.' Using it for general wellness alone may not qualify.
Check retailer websites (e.g., stelo.com) for FSA/HSA payment indicators.
Legitimate vendors often display FSA/HSA badges or have help articles confirming eligibility. This adds confidence that your purchase will be approved for reimbursement.
Read independent reviews focusing on accuracy and user experience for non-diabetics.
As insurance does not cover these, you are paying out-of-pocket. Ensure the device meets your needs for tracking glucose trends related to prediabetes, PCOS, or diet response.
Look for promotional offers or starter kits that reduce initial cost.
Some vendors offer first-month discounts. Using FSA/HSA funds on a discounted starter kit can maximize your account's purchasing power.
Execute the Purchase Correctly
How you pay matters. Use your debit card directly or prepare for a reimbursement claim to ensure smooth otc cgm hsa fsa eligibility validation.
Use your FSA/HSA debit card at the online checkout if available.
This is the simplest method. The transaction is directly deducted from your pre-tax account, requiring no additional paperwork if the merchant code is correct.
If paying with a personal card, save the full itemized receipt immediately.
You will need this for reimbursement. The receipt must show the merchant name, date, product description (e.g., 'Dexcom Stelo Sensor Pack'), and total amount paid.
Ensure the receipt notes the device is an over-the-counter medical device.
This description helps your plan administrator quickly identify the expense as eligible under the CARES Act OTC expansion, reducing back-and-forth questions.
Submit your reimbursement claim through your provider's portal or app promptly.
Do not delay. FSA claims often have a deadline (usually 90 days after the plan year ends). Submitting quickly gets you your money back and uses your funds before they are lost.
Keep a digital and physical copy of all purchase and reimbursement records.
Maintain records for three years in case of an IRS audit. You must be able to prove the expense was qualified, which your receipts and approval confirm.
For subscription models, note the recurring charge date and amount.
Each monthly payment is a separate eligible expense. Track these for accurate record-keeping and to ensure you have sufficient FSA/HSA funds available each month.
Maximize Long-Term Tax and Health Benefits
After your purchase, integrate the device into your health strategy and plan for future FSA/HSA contributions. This turns a one-time buy into ongoing tax-advantaged care.
Calculate your actual tax savings based on your marginal tax rate.
Estimate your savings of 20 to 30 percent. For a $1,068 annual cost, this is $250 to $270. Knowing this figure helps justify the expense and plan future health purchases.
Adjust your next open enrollment FSA contribution to cover the annual CGM cost.
If you spend $1,068 yearly, consider increasing your FSA election by at least that amount for the next plan year to cover it with pre-tax dollars again.
Explore investing your HSA funds if you pay for the CGM with other cash.
If your HSA balance is high, pay for the CGM out-of-pocket, save the receipt, and let your HSA funds grow tax-free. You can reimburse yourself years later.
Use CGM data to inform discussions with your doctor about metabolic health.
The device provides actionable data. Sharing trends with a healthcare professional can lead to better management of conditions like prediabetes, supporting the medical necessity of the expense.
Review other eligible OTC items you can purchase with remaining FSA funds.
The CARES Act also covers OTC medications, menstrual care products, and other devices. Use your balance wisely before it expires to maximize your tax advantage.
When You Complete This Checklist
By finishing this checklist, you will have successfully used your HSA or FSA to purchase an over-the-counter continuous glucose monitor, saving 20 to 30 percent on its cost. You will have a clear record for tax purposes and a plan to fund future metabolic health expenses with pre-tax dollars, turning confusion about otc cgm hsa fsa eligibility into confident, actionable steps.
Pro Tips
- Buy a multi-month supply before your plan year ends if you have FSA funds to use. The 3-month supply of Stelo costs $1,008, a solid way to spend down your balance.
- If your FSA/HSA card is declined at checkout, do not assume the item is ineligible. The merchant category code might be wrong. Pay normally and file for reimbursement with a detailed receipt.
- For maximum tax savings, self-employed individuals should fund an HSA directly, as contributions are deductible above the line, reducing both income and self-employment tax.
- Document your metabolic health condition (e.g., prediabetes, PCOS) in your personal records. While no prescription is needed, this supports the expense as 'diagnosis-related' if ever questioned.
- Set a calendar reminder for open enrollment to increase your FSA election if you plan to buy an OTC CGM next year. The 2026 FSA limit is $3,400 per employee.
Frequently Asked Questions
Are over-the-counter CGMs really FSA/HSA eligible without a prescription?
Yes. The CARES Act of 2020 permanently expanded eligibility to include OTC medical devices, including CGMs, without a prescription under IRS Code Section 213(d). This applies to the 2026 plan year. However, your specific FSA or HSA plan administrator must approve the expense, so you should verify with them before purchasing.
What is the difference between an OTC CGM and a prescription CGM for FSA/HSA?
Prescription CGMs like Dexcom G7 require a doctor's prescription and often a Letter of Medical Necessity for reimbursement. OTC CGMs like Stelo and Lingo, cleared for adults 18+ not using insulin, do not require these documents. Both are qualified expenses, but the OTC path removes the prescription barrier, simplifying the otc cgm hsa fsa eligibility process.
How much can I save using my HSA or FSA for an OTC CGM?
Using pre-tax funds typically yields a 20 to 30 percent savings based on your tax bracket. For the Dexcom Stelo's $1,068 annual subscription cost, this equates to $250 to $270 back. The exact amount depends on your federal and state income tax rates, plus FICA taxes if funded through a cafeteria plan.
Will my health insurance cover an OTC continuous glucose monitor?
Most standard insurance plans do not cover OTC CGMs for non-diabetic or prediabetic users. Insurance typically only covers prescription CGMs for individuals with diabetes. Therefore, FSA and HSA funds are the primary way to pay for OTC devices like Stelo and Lingo with tax-advantaged dollars.
Can I use my FSA or HSA debit card to buy an OTC CGM online?
Yes, if the online retailer is coded as a medical supplier. Vendors like stelo.com and hellolingo.com accept FSA/HSA debit cards. Major retailers like Amazon and Walgreens also have designated FSA/HSA storefronts. If your card is declined, pay with a regular card and submit the itemized receipt for reimbursement from your account.
What happens to my FSA money if I don't use it all by year-end?
FSA rules vary. Your plan may offer a grace period of up to 2.5 months or allow a carryover of up to $680 into the next plan year (2026). You must check your plan documents. HSA funds have no use-it-or-lose-it rule; they roll over indefinitely and can be invested for future healthcare or retirement costs.
Are OTC CGM supplies like sensors and subscriptions also eligible?
Yes. Recurring costs for sensors and monthly subscriptions for FDA-cleared OTC CGMs are qualified medical expenses. Keep all receipts and subscription confirmations. For subscription models, each monthly charge is an eligible expense that you can pay for or reimburse from your FSA or HSA.
