fsa coverage stelo cgm Checklist (2026) | HSA Tracker

Dexcom Stelo launched in August 2024 as the first FDA-cleared over-the-counter glucose sensor, priced at $99 for a 30-day pack. Its direct-to-consumer model means it's not covered by insurance, but the manufacturer states it is a qualified medical expense for FSA and HSA funds. This creates a specific opportunity and a potential administrative hurdle for users. This fsa coverage stelo cgm checklist is designed for W2 employees, the self-employed, and families who want to use pre-tax dollars for this new health tool while avoiding IRS issues. We cover the exact steps to verify eligibility, make the purchase correctly, and document it for reimbursement under the 2026 FSA limits.

Pre-Purchase Verification for FSA Coverage of Stelo CGM

Before you spend any money, confirm that your specific FSA or HSA plan will reimburse for the Dexcom Stelo. This step prevents the headache of being stuck with a non-reimbursable expense. These checks address common pain points like plan administrator confusion and fear of audit.

Contact your FSA/HSA administrator or check your plan's online eligible expenses list.

Eligibility can vary by employer plan. The administrator has the final say, even if Dexcom says it's qualified. Getting confirmation in writing (email) provides a paper trail if your claim is later questioned.

CriticalVerification

Ask if a prescription or Letter of Medical Necessity (LMN) is required for OTC CGMs.

Some administrators treat all CGMs the same and require a prescription for substantiation. Knowing this upfront lets you get the document from your doctor before buying, avoiding reimbursement delays.

CriticalVerification

Verify your 2026 FSA election and current account balance.

The 2026 health FSA limit is $3,400. You need to ensure you've elected enough funds and that money is available. A Stelo subscription costs about $89/month, so plan your annual budget accordingly.

ImportantVerification

Determine if your FSA is a 'use-it-or-lose-it' plan or offers the $680 carryover.

If you have a carryover provision, you can use prior-year funds for Stelo. If not, you must spend all funds within the plan year, making a subscription a good way to use consistent amounts.

ImportantVerification

Confirm the exact reimbursement process: debit card, claim form, or app submission.

Each plan has a different method. Knowing whether you can use a debit card at checkout or must file a manual claim dictates how you shop and track paperwork.

How to Purchase Stelo for Optimal FSA/HSA Reimbursement

How you buy Stelo impacts your ability to get reimbursed smoothly. This section covers purchase methods, pricing choices, and documentation collection to satisfy IRS substantiation rules and avoid missing tax deductions.

Decide between the one-time purchase ($99) or subscription ($89/month).

A one-time purchase gives a single, straightforward receipt. A subscription provides regular monthly receipts, which can help spend down your FSA evenly but requires tracking multiple transactions.

ImportantPurchase

Buy directly from Dexcom's website or an authorized retailer.

Purchasing from an official source ensures you get a valid receipt with the proper merchant name and item description, which is required for reimbursement. Third-party marketplaces may not provide adequate documentation.

CriticalPurchase

Use your FSA debit card if your plan allows direct payment for Stelo.

This is the easiest method, as the transaction is automatically deducted from your FSA. If the card is declined, it's an immediate flag that you need to submit a manual claim with documentation.

ImportantPurchase

If paying personally, save the digital order confirmation email immediately.

This email is your primary receipt. It must show date, seller, item description (Dexcom Stelo), and amount paid. Print a PDF copy and store it in your tax records folder.

CriticalPurchase

Also save the shipping confirmation or any packing slip.

The shipping document corroborates the purchase date and final cost, adding a second layer of proof for your FSA administrator if the initial receipt is questioned.

Nice to HavePurchase

Consider buying a 3-month supply upfront if you have expiring FSA funds.

If you have 'use-it-or-lose-it' funds at year-end, a larger one-time purchase can help avoid forfeiting money. Check if Dexcom offers multi-pack discounts.

Documentation and Submission for Your FSA Claim

Substantiation is key to IRS compliance. This checklist ensures you have all the required documents and submit them correctly to get your money back without triggering an audit flag. It addresses the pain point of fear of IRS audits.

Ensure your receipt has date, merchant name, item description, and price.

IRS rules require this information to prove the expense was for a qualified medical item. A vague receipt like 'online purchase' will be rejected by your FSA administrator.

CriticalDocumentation

Attach a copy of any required prescription or Letter of Medical Necessity.

Even though Stelo is OTC, your plan may require this. Submitting it with your initial claim prevents back-and-forth requests and speeds up reimbursement.

ImportantDocumentation

Complete your plan's reimbursement claim form fully and accurately.

Missing information on the form is a common reason for denial. Double-check your member ID, dates, and amount requested against your receipt.

CriticalDocumentation

Submit the claim via your plan's portal, app, or email as instructed.

Using the wrong submission channel can delay processing. Follow your administrator's specific guidelines to ensure your claim enters their workflow correctly.

ImportantDocumentation

Record the claim submission date and any confirmation number.

This creates a log for you to follow up if reimbursement takes longer than the stated processing time (often 7-14 business days).

Nice to HaveDocumentation

File all documents (receipts, forms, approvals) in your permanent tax records.

The IRS can audit HSA/FSA distributions for up to three years after filing. Having organized records proves the expense was qualified and protects you from penalties.

CriticalDocumentation

Ongoing Management and Year-End FSA Coordination

Using Stelo is a recurring expense. This section helps you integrate it into your annual FSA strategy, align with contribution limits, and coordinate with other healthcare costs to maximize your tax-advantaged dollars.

Mark your calendar for monthly subscription charges if you chose that plan.

Monitoring charges ensures you catch any billing errors and can match each transaction to an FSA reimbursement claim, keeping your accounting accurate throughout the year.

ImportantManagement

Track your total annual FSA spending on Stelo against your $3,400 limit.

A $89/month subscription totals $1,068 per year. You need to budget the remaining $2,332 for other eligible expenses like dental work, vision care, or co-pays.

ImportantManagement

Re-evaluate Stelo's value during your next Open Enrollment period.

Your health needs or financial situation may change. Decide if continuing Stelo is the best use of your FSA dollars compared to other anticipated medical expenses for the upcoming year.

Nice to HaveManagement

If you have an HSA, decide between immediate reimbursement or letting funds grow.

HSAs allow you to pay out-of-pocket now and reimburse yourself later tax-free. Letting the HSA funds invest and grow can be a powerful retirement healthcare strategy.

ImportantManagement

Coordinate Stelo expenses with a Limited-Purpose FSA (LPFSA) if you have one.

An LPFSA, also with a $3,400 limit for 2026, covers only dental and vision. Stelo is a medical expense, so it must be paid from your general health FSA, not your LPFSA.

ImportantManagement

Plan for the $100 FSA limit increase from 2025 to 2026 when budgeting.

The 2026 limit is $3,400, up from $3,300 in 2025. This extra $100 can cover more than one month of a Stelo subscription, giving you slightly more flexibility in your annual healthcare budget.

When You Complete This Checklist

By following this checklist, you will confidently use your FSA or HSA to purchase the Dexcom Stelo CGM, ensuring full tax savings and compliance. You'll have a clear system for verification, purchase, documentation, and ongoing management, turning a potentially confusing expense into a smooth, optimized part of your healthcare financial plan.

Pro Tips

  • Buy your first Stelo pack as a one-time purchase for $99 before setting up a subscription. This gives you a clean, single receipt for your FSA claim and lets you test the system without a recurring charge.
  • If your FSA uses a debit card, try using it directly on Dexcom's website. If the transaction is declined, it's a quick signal that your administrator may require pre-approval or extra paperwork.
  • For the self-employed using an HSA, the Stelo cost is an eligible medical expense you can reimburse yourself for tax-free at any time, even years later. Keep perfect records in your tax files.
  • HR managers: consider sending a plan communication specifically about OTC CGMs if employees ask. Clarify if a Letter of Medical Necessity from a doctor is needed to streamline approvals and reduce help desk tickets.

Frequently Asked Questions

Is Dexcom Stelo definitely FSA and HSA eligible?

Dexcom markets Stelo as HSA/FSA eligible and states on its FAQ that the glucose biosensor is a qualified medical expense. However, actual reimbursement depends on your specific plan administrator's rules. Some administrators may require additional documentation, like a prescription or Letter of Medical Necessity, even for this OTC product. Always check with your plan before purchasing.

What's the difference between Stelo and prescription CGMs like Dexcom G7 for FSA use?

Stelo is available over-the-counter without a prescription, while Dexcom G7 requires one. Stelo is intended for adults 18+ who do not use insulin and do not experience hypoglycemia, including those with prediabetes or type 2 diabetes not on insulin. For FSA/HSA, a prescription CGM like the G7 almost always requires a prescription receipt for reimbursement. Stelo's OTC status changes the documentation needed, but plan rules vary.

How much does Stelo cost, and how does it fit within FSA contribution limits?

Stelo costs $99 for a one-time purchase of a 2-sensor, 30-day pack, or $89 per month with a subscription. The 2026 health FSA contribution limit is $3,400 per employee. A year of Stelo on the subscription plan would cost about $1,068, which uses a significant portion of your FSA but is a fully eligible expense if your plan approves it.

What receipt do I need for FSA reimbursement for Stelo?

You need a detailed receipt showing the date of purchase, merchant name (e.g., Dexcom), a clear item description (e.g., 'Dexcom Stelo Glucose Sensor 30-day pack'), and the amount paid. Save both the order confirmation email and any shipping receipt. Since Stelo is OTC, a prescription is not inherently required, but your administrator might ask for one or a Letter of Medical Necessity to substantiate the medical purpose.

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

According to the Association of Diabetes Care & Education Specialists (ADCES), Stelo is appropriate for adults without diabetes who want to track glucose responses. For FSA/HSA purposes, the expense must be for the diagnosis, cure, mitigation, treatment, or prevention of disease. Using it for general wellness without a medical condition may not qualify. It's designed for those with prediabetes or managing metabolic health, which typically meets the IRS standard.

What are the other OTC CGM options besides Stelo?

As of late 2024, market analysis points to two main OTC CGM products: Dexcom Stelo and Abbott Lingo. Both are marketed as FSA-eligible. If your plan denies Stelo, you could inquire about Lingo as an alternative. Always verify directly with your FSA/HSA provider and compare the devices' features, costs, and intended user profiles before switching.

How does the 2026 FSA carryover rule affect buying a Stelo subscription?

For plans that allow it, the 2026 health FSA carryover limit is $680. If you have funds left over from 2025, you could use that carryover amount to pay for several months of Stelo upfront in early 2026. This helps if you want to start monitoring but haven't funded your new year's FSA yet. Check if your specific plan uses the carryover option or the grace period.
