FSA Eligible Diabetes Supplies: The Complete 2025 List

If you're managing diabetes, your Flexible Spending Account (FSA) is one of the most powerful — and most underused — tools in your financial arsenal. Every year, millions of Americans with diabetes leave hundreds or even thousands of dollars on the table simply because they don't know what qualifies. This guide fixes that. Below is the most comprehensive, up-to-date list of FSA eligible diabetes supplies for 2025, plus everything you need to know about deadlines, rollovers, and how to spend your FSA dollars wisely before they disappear.

What Is a Flexible Spending Account (FSA)?

A Flexible Spending Account (FSA) is an employer-sponsored benefit account that lets you set aside pre-tax dollars to pay for eligible healthcare expenses. In 2025, the IRS contribution limit for a healthcare FSA is $3,300 per person (up from $3,050 in 2024). Because contributions come out of your paycheck before federal income tax, Social Security tax, and Medicare tax are applied, most participants save between 25–40% on every qualifying purchase depending on their tax bracket.

According to the Employee Benefit Research Institute, approximately 35 million Americans have access to an FSA through their employer — yet a significant portion of those accounts lose money each year due to the "use it or lose it" rule. For people with diabetes who have predictable, recurring supply needs, an FSA is an exceptional way to reduce out-of-pocket costs dramatically.

FSA vs. HSA for Diabetics: What's the Difference?

Both FSAs and Health Savings Accounts (HSAs) let you spend pre-tax money on eligible medical expenses, but they work very differently. Understanding which account you have — and its specific rules — is critical before you start shopping for diabetes supplies.

Bottom line for diabetics: If you have access to an HSA, it's generally superior for long-term savings because funds roll over indefinitely. However, FSAs still offer significant tax savings for annual supply purchases. The eligible items are virtually identical under IRS rules — so this guide applies to both.

The Complete 2025 List of FSA Eligible Diabetes Supplies

The following items are FSA eligible for people with diabetes in 2025. Thanks to the CARES Act, most of these no longer require a Letter of Medical Necessity (LMN) or prescription to purchase with FSA funds — though some employers may still request documentation. Always check with your FSA administrator if you're uncertain.

Continuous Glucose Monitors (CGMs) and Sensors

CGM systems — including the Dexcom G7, Libre 2, Libre 3, and Medtronic Guardian — are fully FSA eligible. This includes:

• The CGM receiver or reader device
• Replacement CGM sensors
• CGM transmitters
• CGM overpatch adhesive covers (used to extend sensor wear and prevent premature detachment)

CGM sensors are among the highest-cost recurring expenses for people with diabetes, making FSA purchasing especially impactful. A 3-month supply of Libre 3 sensors, for example, can cost $250–$400 without insurance — purchasing with FSA dollars saves real money.

Blood Glucose Meters and Test Strips

• Blood glucose meters (glucometers)
• Blood glucose test strips (all brands)
• Lancets and lancing devices
• Control solution (used to verify meter accuracy)

Test strips and lancets are the most commonly purchased FSA-eligible diabetes items. The American Diabetes Association estimates that people who test multiple times daily can spend $600–$1,200 per year on strips alone — all of which can be paid with pre-tax FSA dollars.

Insulin and Insulin Delivery Supplies

• Insulin (all types: rapid-acting, long-acting, premixed)
• Insulin syringes
• Insulin pen needles
• Insulin pump supplies (cartridges, infusion sets, reservoirs)
• Insulin pump devices (with LMN in most cases)
• Sharps containers for safe disposal

Important note on GLP-1 medications: Medications like Ozempic, Mounjaro, Victoza, and Trulicity are FSA eligible when prescribed for diabetes management. However, if prescribed solely for weight loss without a diabetes diagnosis, eligibility may vary by FSA plan administrator.

Insulin Storage and Travel Accessories

Proper insulin storage is medically necessary for people with diabetes — which is why insulin coolers and travel cases qualify as FSA eligible medical devices when they are designed and marketed specifically for insulin storage.

• Insulin cooling cases and travel wallets
• Medical-grade insulin refrigeration devices
• TSA-approved insulin travel organizers

Glucose Tablets and Hypoglycemia Treatment

• Glucose tablets (all brands)
• Glucose gels
• Glucagon emergency kits (prescription required)
• Fruit juice and regular soda used to treat hypoglycemia (generally not FSA eligible as they are food items — glucagon and glucose tablets are the correct FSA-eligible alternatives)

Medical Alert Identification

• Medical alert bracelets and necklaces that identify the wearer as having diabetes
• Medical ID cards

Medical alert IDs are a critical safety item for people with diabetes, particularly those who use insulin. If you lose consciousness due to hypoglycemia, a medical alert ID can tell first responders what's wrong and what treatment you need. These qualify as FSA eligible medical devices.

Other FSA Eligible Diabetes Items

• Diabetic compression socks and stockings (designed for therapeutic use)
• Monofilament testing tools for neuropathy screening
• Diabetic wound care supplies
• Continuous glucose monitor overpatch adhesives
• Alcohol swabs (for injection site preparation)
• Diabetes education programs and classes
• Visits to a Certified Diabetes Care and Education Specialist (CDCES)
• Prescription copays for diabetes medications

What Is NOT FSA Eligible for Diabetes?

Just as important as knowing what qualifies is knowing what doesn't. The following items are generally not FSA eligible, even for people with diabetes:

• General health foods, vitamins, or supplements — even if marketed "for diabetics" (cinnamon supplements, chromium, alpha-lipoic acid, etc. do not qualify without a specific prescription)
• Exercise equipment — treadmills, fitness trackers, gym memberships (even though exercise is medically recommended for diabetes management)
• Cosmetic items — even if marketed for people with diabetes
• Convenience foods labeled "diabetic-friendly" — food is not a qualifying medical expense
• Smartwatches that display CGM data (the watch itself does not qualify; the CGM does)
• Insurance premiums — generally not FSA eligible (HSA holders have more flexibility here)
• Teeth whitening or cosmetic dental procedures

When in doubt, check with your FSA administrator or look up the item in the IRS Publication 502, which outlines all eligible medical and dental expenses.

How to Use Your FSA at MDS Diabetes

MDS Diabetes (mdsdiabetes.com) offers a curated selection of FSA eligible diabetes supplies, including CGM accessories, insulin cooling cases, overpatch adhesives, medical IDs, and more. Here's how to use your FSA when shopping:

1. Use your FSA debit card at checkout — most FSA administrators issue a Visa or Mastercard debit card that can be used anywhere eligible items are sold. Simply enter your FSA card details at checkout like a regular debit card.
2. Save your receipts — your FSA administrator may request itemized receipts for substantiation. Keep records of every purchase.
3. Check your FSA balance before year-end — log into your FSA portal and check exactly how much you have remaining before December 31.
4. Contact your FSA administrator if an item is declined — sometimes eligible items are declined due to incorrect product category codes (merchant category codes). You may be able to submit for manual reimbursement.

The December 31 Deadline: Don't Lose Your FSA Money

The most critical rule of FSAs is the "use it or lose it" provision. If you don't spend your FSA funds by the deadline — typically December 31 — you forfeit whatever remains in the account. The IRS reported that Americans forfeit an estimated $400 million in FSA funds each year. For people with diabetes who have predictable, ongoing supply needs, there is absolutely no reason to leave money behind.

Year-end FSA shopping checklist for diabetics:

• Stock up on 3–6 months of test strips and lancets
• Order replacement CGM sensors
• Purchase CGM overpatches and adhesive accessories
• Buy a high-quality insulin travel cooler
• Replace your medical alert ID if it's worn or outdated
• Purchase glucose tablets in bulk
• Schedule any overdue diabetes-related medical appointments

FSA Grace Period and Rollover Rules

The strict December 31 deadline has important exceptions you should know about:

Grace Period Option

Some employers offer a 2.5-month grace period, extending your spending window to March 15 of the following year. During this grace period, you can continue spending prior-year FSA funds. Ask your HR department or FSA administrator whether your plan includes this provision.

Rollover Option

Under IRS rules updated in 2021, employers may allow FSA participants to roll over up to $640 in 2025 (indexed annually for inflation) into the next plan year. This is separate from the grace period — an employer can offer one or the other, but not both.

FSA Rollover Comparison

Action item: Right now, log into your FSA account online or call the number on your FSA card to find out (1) your exact balance, (2) whether your plan has a grace period or rollover, and (3) your specific spending deadline.

How Much Can You Save Using FSA for Diabetes Supplies?

The tax savings from using an FSA are significant. Consider a person with diabetes who spends $2,500 per year on supplies and is in the 22% federal tax bracket:

• Without FSA: $2,500 spent with after-tax dollars
• With FSA: $2,500 spent with pre-tax dollars = effective cost of approximately $1,850 (saving ~$650)

When you factor in state income taxes and FICA taxes, the savings can be even greater — often 30–40% on every dollar spent. Over a lifetime of diabetes management, this adds up to tens of thousands of dollars.

Frequently Asked Questions: FSA Eligible Diabetes Supplies

Are CGM sensors FSA eligible?

Yes. CGM sensors, transmitters, and receivers for systems like Dexcom G7, FreeStyle Libre 2 and 3, and Medtronic Guardian are all FSA eligible. You do not need a prescription to use FSA funds for CGM supplies under current IRS rules, though your FSA administrator may request documentation.

Can I use my FSA to buy insulin?

Yes. All forms of insulin are FSA eligible — including rapid-acting (Humalog, NovoLog, Admelog), long-acting (Lantus, Basaglar, Toujeo), and premixed formulations. Injectable GLP-1 medications like Ozempic and Victoza prescribed for Type 2 diabetes management are also FSA eligible.

Are insulin coolers FSA eligible?

Yes, insulin coolers that are specifically designed for medical use — such as the VIVI CAP — are FSA eligible as medical devices. General-purpose coolers or lunch bags would not qualify, but purpose-built insulin storage accessories do.

What happens to my FSA money if I don't use it by December 31?

In a standard FSA with no grace period or rollover, unused funds are forfeited to your employer at the plan year's end. Some plans offer a 2.5-month grace period (until March 15) or allow a rollover of up to $640 into the next year. Check with your HR department or FSA administrator to understand your specific plan rules.

Can I use FSA for diabetic shoes or compression socks?

Therapeutic diabetic compression socks prescribed for a medical condition (such as diabetic peripheral neuropathy or edema) are FSA eligible. Standard compression socks without a medical recommendation are generally not eligible. Custom diabetic shoes prescribed by a physician for a diabetes-related foot condition are also FSA eligible.

Do I need a prescription to buy diabetes supplies with my FSA?

For most diabetes supplies — including test strips, lancets, glucose tablets, and CGM sensors — you no longer need a prescription thanks to the CARES Act of 2020, which permanently expanded FSA eligibility for OTC medical products. Prescription medications like insulin, glucagon, and injectable diabetes drugs still require a valid prescription to purchase, but that prescription is part of your normal diabetes care anyway.

Is the FSA the same as insurance? Can I use both?

No — your FSA is separate from your health insurance. You can absolutely use both: pay your insurance copay or deductible with your FSA, and also use FSA funds to purchase diabetes supplies that your insurance doesn't fully cover. Many people with diabetes use their FSA to cover the "gap" between what insurance pays and what they owe out of pocket.
