We see all kinds of interesting ineligible expenses your FSA, HSA, or HRA won’t cover. It can be confusing because something might seem obviously eligible, but how do we know for sure? This article highlights some of the most surprising ineligible expenses, explains why they’re not covered, and offers practical tips to keep your plan compliant and your employees informed.
FSAs, HSAs, and HRAs help employees stretch every healthcare dollar and help employers offer more competitive benefits in a tax-efficient way. But even with a long list of eligible expenses, there are still plenty of costs that feel “medical” but don’t qualify under IRS rules. That’s where confusion—and sometimes costly mistakes—tend to show up.
Why Some “Medical” Expenses Are Still Ineligible
FSAs, HSAs, and HRAs don’t get to make up their own eligibility rules. They’re tied to the IRS definition of “medical care” in Section 213(d) of the Internal Revenue Code.
In simple terms, an expense must be primarily to diagnose, cure, mitigate, treat, or prevent a disease, or affect a structure or function of the body. If the main purpose is general health, appearance, convenience, or something non-medical, it usually will not qualify.
Publication 502 (Medical and Dental Expenses) is the IRS’ reference guide, and most plans follow it closely. That’s why FSAs, HSAs, and HRAs tend to agree on what is and isn’t eligible—even though they differ in who owns the funds, how contributions work, and whether the money rolls over.
Understanding that framework makes the following “interesting” ineligible expenses easier to explain to employees.
Interesting Expenses Your Plan Won’t Cover
Medical marijuana and other controlled substances
Even in states where medical or recreational marijuana is legal, the IRS still treats marijuana as an illegal controlled substance under federal law. Because FSAs, HSAs, and HRAs are governed by federal tax rules, marijuana-related products and dispensary purchases are not eligible expenses—even with a doctor’s recommendation.
Treatment programs for substance use disorders, however, generally are eligible when they meet the normal rules for medical care.
Prescriptions from non-U.S. or unlicensed pharmacies
Employees may try to save money by ordering prescriptions from foreign or online pharmacies. But if the drugs are imported into the U.S. in a way that’s not allowed under federal law, those purchases usually cannot be reimbursed.
In most cases, your plan should not reimburse:
- Drugs imported from overseas pharmacies, or
- Drugs that are not legal in the U.S., even if they’re legal elsewhere.
Some expenses may be eligible when a person legally purchases and uses medication while physically in another country, but you’ll want clear documentation and typically a conservative plan rule here.
Prepaid treatment packages and “visit credits”
Chiropractors, physical therapists, and wellness clinics often sell bundles of visits at a discount. It may feel like one big medical expense, but the IRS cares about when services are actually received.
Prepayments for services not yet provided are typically not eligible at the time of purchase. Instead, each visit becomes an eligible expense as it occurs. That means claims should be reimbursed one visit at a time, based on documentation showing the date of service and amount applied.
Marriage counseling and non-medical therapy
Mental health treatment is generally considered medical care when it’s used to treat a diagnosed condition. Counseling or therapy for depression, anxiety, or another diagnosable disorder often qualifies.
Marriage counseling and therapy used for general personal development or relationship improvement do not. Even if a licensed professional provides the service, if it isn’t tied to a diagnosed medical condition, it typically won’t be eligible.
Child support and non-qualifying dependent care
Dependent Care FSAs only reimburse expenses that allow the employee (and spouse, if applicable) to work or look for work. That excludes several costs that parents often ask about:
- Child support payments
- Daycare paid by a non-custodial parent
- School tuition for kindergarten and above
Before- and after-school care may be eligible, but payments that are more about education or legal obligations than care so the parent can work will not qualify.
Insurance premiums (with narrow exceptions)
Insurance premiums are one of the most misunderstood categories.
- Health FSA: Health insurance premiums are not eligible expenses.
- HSA: Most health insurance premiums are not qualified, with limited exceptions such as COBRA premiums, certain premiums while unemployed, and specific Medicare premiums after age 65.
- HRA: Some HRAs can reimburse premiums, but only if they are designed to do so (for example, ICHRAs or QSEHRAs) and meet strict IRS and ACA requirements.
For a standard Health FSA, assume premiums are ineligible unless your documents clearly say otherwise and your legal advisors sign off.
Teeth whitening, cosmetics, and everyday toiletries
If an expense is primarily cosmetic or for general grooming, it’s usually not eligible—even if it’s purchased at a pharmacy.
Typical ineligible items include:
- Teeth whitening for cosmetic reasons
- Cosmetic surgery that doesn’t treat a disease or deformity
- Toiletries like shampoo, toothpaste, soap, and makeup
Medically necessary procedures and prescription-strength medicated products may be eligible, but you’ll need documentation that they’re being used to treat a specific condition.
Other Gray Area Expenses to Watch
Gym memberships and general wellness
Gym memberships, fitness classes, and sports leagues are almost always ineligible when used for general health. Even if a doctor says “You should exercise more,” that recommendation alone doesn’t make a gym membership a medical expense.
In rare cases, a membership might be eligible if it is prescribed to treat a diagnosed condition and is used solely for that purpose, but most employers choose a conservative approach and treat gym memberships as ineligible across the board.
Vitamins, supplements, and nutrition programs
Over-the-counter vitamins and supplements are typically not eligible when taken for general wellness. Weight-loss programs are generally ineligible when they’re about appearance or general health.
These costs may become eligible when there is a diagnosed condition (for example, obesity or a specific deficiency) and the program or supplement is prescribed as part of a treatment plan. In those situations, a letter of medical necessity is critical.
What Happens If Employees Use Funds for Ineligible Expenses?
Ineligible expenses are more than a customer service hassle—they can create tax and compliance problems.
For employees:
- FSA and HRA reimbursements for ineligible expenses can be treated as taxable income if not corrected.
- HSA distributions used for non-qualified expenses are taxable and generally subject to an additional penalty for account holders under age 65.
For employers:
- Consistently reimbursing ineligible expenses or failing to properly substantiate claims can jeopardize the tax-favored status of the entire cafeteria plan, potentially creating payroll tax exposure.
- The IRS expects robust substantiation; “rubber-stamping” claims or allowing self-certification isn’t compliant.
Getting eligibility right protects both employees and the plan.
How Employers Can Reduce Ineligible Claims (and How Flyte Helps)
You can’t prevent every questionable receipt, but you can dramatically reduce ineligible claims with a few practical steps:
- Educate at open enrollment. Clearly explain what these accounts can and can’t pay for, and highlight common problem categories like premiums, gym memberships, and cosmetic services.
- Leverage your administrator’s tools. Use debit card controls, mobile apps, and reporting to help employees make informed choices and to spot trends in denied claims.
- Train HR and payroll on red flags. Give your internal teams simple guidelines for when to approve, when to deny, and when to escalate questions.
