Wearable health trackers like the Oura Ring have become hugely popular, and a familiar question tends to follow close behind: can I pay for one with my HSA or FSA? It is a fair thing to wonder. These accounts are meant for health, and a ring that tracks your sleep, heart rate, and activity certainly feels health-related.
The honest answer is "sometimes, but not automatically." Understanding why can save you from a surprise tax bill down the road, and it can help you decide whether there is a legitimate path to using those pre-tax dollars for a device like this.
Quick Answer
An Oura Ring, like most general wellness wearables, is usually not an HSA- or FSA-eligible expense on its own. The IRS only allows these accounts to pay for "qualified medical expenses," and a device that promotes general health does not qualify unless a licensed medical provider documents that you need it to treat or manage a specific medical condition, usually through a Letter of Medical Necessity. With a valid letter, it may become eligible.
What counts as a qualified medical expense
HSAs and FSAs can only be used tax-free for what the tax law calls qualified medical expenses. Under the Internal Revenue Code, that means costs for the diagnosis, cure, mitigation, treatment, or prevention of disease, or for affecting a structure or function of the body. The key idea is that the expense has to be tied to addressing a medical condition.
Items that simply promote general good health do not make the cut. That is why things like a standard gym membership, most vitamins and supplements, and general wellness gadgets are typically not reimbursable on their own. The IRS spells out the categories in Publication 502, and Publication 969 explains how HSAs and FSAs work.
Where wellness wearables fall
A general-purpose health tracker sits squarely in the "general wellness" bucket for most people. It is marketed to help you sleep better, move more, and understand your body, all of which are good things, but none of which the IRS treats as the treatment of a specific medical condition. So by default, a ring like this is not a qualified medical expense.
The line the IRS draws is between promoting general health, which does not qualify, and treating or managing a diagnosed condition, which can. Whether a particular wearable crosses that line depends entirely on your personal medical situation, not on the product itself.
How a Letter of Medical Necessity changes things
This is where a Letter of Medical Necessity, often shortened to LMN, comes in. If a licensed provider determines that you need a device to diagnose, treat, or manage a specific medical condition, they can write a letter saying so. With a valid LMN that ties the device to a genuine medical need, an item that would otherwise be ineligible may become reimbursable through your HSA or FSA.
A good letter generally names the condition, explains why the provider recommends the device, and notes how long it is needed. Keep that letter with your tax and account records in case your plan administrator or the IRS ever asks you to back up the expense.
What about Truemed, Flex, and similar services
You may have seen checkout options from companies such as Truemed or Flex that promise to help you buy wellness products with HSA or FSA funds. These services generally work by connecting you with a provider who evaluates whether you qualify for a Letter of Medical Necessity, and if you do, they help you use your account to pay.
Here is the important caveat: these services do not change the IRS rules. The Letter of Medical Necessity still has to reflect a real medical need. A letter obtained simply to get a discount on a gadget you wanted anyway can be challenged, and the responsibility for a proper expense ultimately falls on you, the account holder, not on the retailer or the service.
The cost of getting it wrong
If you use HSA or FSA money for something that turns out not to be a qualified expense, the amount is generally treated as taxable income. For an HSA, if you are under 65, an additional tax, currently 20 percent, can also apply on top of the regular tax. That is a steep price for guessing wrong, which is exactly why documentation and a little caution up front are worth it.
A few 2026 numbers worth knowing
For plan years beginning in 2026, the health FSA contribution limit is 3,400 dollars, and if your plan allows a carryover, up to 680 dollars can roll into the following plan year. FSAs are generally use-it-or-lose-it, so it helps to plan your spending. HSA contribution limits for 2026 are 4,400 dollars for self-only coverage and 8,750 dollars for family coverage, and HSA funds roll over year to year and stay yours to keep, even if you change jobs or plans.

How to check your own plan
Start by reading your plan documents or calling your HSA or FSA administrator and asking directly whether they accept a Letter of Medical Necessity and, if so, what form they need. Then have an honest conversation with your doctor about whether your situation actually supports a letter. Save your receipts and any letter you receive, and when something is unclear, ask a tax professional rather than relying on a product page. A little homework now is far easier than untangling a disallowed expense later.
A Note From Alisa
As an Enrolled Agent, the one thing I want people to walk away with is this: the phrase "HSA/FSA eligible" on a product page is a marketing line, not an IRS ruling. Whether something qualifies depends on your situation, not on the label the seller put on it. Having said that if you love the Oura ring, get it. They are cool!
Common Questions
Can I buy an Oura Ring with my HSA or FSA?
Usually only if a licensed provider gives you a Letter of Medical Necessity showing you need it to treat or manage a specific medical condition. Without that, a general wellness ring is typically not a qualified medical expense.
What is a Letter of Medical Necessity?
It is a written statement from a licensed medical provider explaining that a product or service is needed to diagnose, treat, or manage a specific medical condition. It is what can turn an otherwise-ineligible item into a qualified HSA or FSA expense.
A website says the Oura Ring is "HSA/FSA eligible" — is that enough?
Not by itself. "HSA/FSA eligible" is a marketing label. Actual eligibility depends on IRS rules and your own medical situation, and it is your plan administrator, not the retailer, who decides what gets reimbursed.
What happens if I use HSA or FSA funds for something that does not qualify?
The amount is generally treated as taxable income, and for an HSA, if you are under 65, an extra tax of currently 20 percent can apply. That is why keeping documentation and checking the rules first really matters.
How do I find out what my specific plan allows?
Check your plan documents or call your HSA or FSA administrator, ask whether they accept a Letter of Medical Necessity and in what form, and keep your receipts. A tax professional can help if you are unsure.
