What Can I Use My HSA For?

I tend to be a bit of a workout nut. For those of you who know me personally, you may remember that I’m usually up before 4:00 a.m. for my morning workouts, a routine that started years ago as temporary insomnia and somehow evolved into a decade-long habit. It probably also has something to do with the fact that I’m still trying to keep up with my dad, who happens to be a CrossFit trainer in his 70s.

And before you start assuming I’m some completely sleep-deprived lunatic, I’ll have you know that I’m also fighting to keep my eyes open by Final Jeopardy most nights.

Ironically, this schedule has actually worked pretty well since adding an infant to our lives. It’s allowed me to maintain a long-standing commitment to my workouts while still being available to help my wife in the mornings once our little girl wakes up.

I’m also a bit of a gear junkie, so when a new piece of home fitness or recovery equipment hits the market, I usually notice. Lately, the thing grabbing my attention has been the nonstop wave of advertisements for massage guns, recovery systems, and fitness products all claiming to be “HSA-eligible.” As an HSA saver myself, my interest was immediately piqued.

A lot of people think of their Health Savings Account as little more than a medical debit card. Money goes in, prescriptions come out, maybe you pay for a doctor’s visit here and there, and that’s about it.

But HSAs can be significantly more powerful than that if they’re used strategically.

In the right situations, an HSA can function as a healthcare reserve fund, a long-term investment account, a retirement income planning tool, and one of the most tax-efficient accounts available under current law. The challenge is that most people never really get shown the full menu of options.

And honestly, that’s understandable. Healthcare planning already feels complicated enough without trying to decode IRS reimbursement rules at the same time. Sometimes it feels like every healthcare form was intentionally designed by someone who enjoys watching people sigh heavily at kitchen tables.

Still, once you understand the flexibility built into these accounts, the value becomes clearer.

Why HSAs Are So Valuable

Most investment accounts get one major tax benefit.

Traditional retirement accounts may provide a deduction upfront, but withdrawals are taxable later. Roth accounts are funded with after-tax dollars, but qualified withdrawals are tax-free down the road.

HSAs are one of the few accounts that may allow all three benefits simultaneously.

Contributions may be deductible. Investments can grow tax deferred. Qualified medical withdrawals are tax-free.

That combination creates a unique planning opportunity, particularly for higher earners who are already maximizing retirement plans and looking for additional ways to improve long-term tax efficiency.

While it’s important to understand who’s eligible for an HSA, how to invest the funds, what the contribution limits are, and how it pairs with your employer’s medical plan, this article is about something more fun. Spending it.

The Long-Term Investment Approach

Many people contribute to an HSA and immediately spend the balance on current medical expenses. There’s nothing inherently wrong with that approach. But for households that can comfortably cash flow healthcare costs from their regular income, there may be a more efficient strategy available.

Instead of spending the HSA balance each year, some people choose to invest the account and leave it untouched for years or even decades. Current medical expenses are paid out of pocket while the HSA compounds in the background alongside retirement assets.

And under current rules, there is generally no required deadline to reimburse yourself for qualified medical expenses, provided the expense occurred after the HSA was established and proper documentation is maintained.

That means a $3,000 medical bill paid today from your checking account could potentially become a tax-free reimbursement years down the road.

Some households take this strategy even further by paying eligible medical expenses with a rewards credit card first. They collect the travel points, cashback, or other rewards today, pay the balance off from cash flow, and allow the HSA to continue growing untouched. Then later in retirement, particularly during years when markets are down or taxable income is elevated, they may choose to reimburse themselves tax-free using years of accumulated medical receipts. In effect, the HSA can quietly become a reserve of future tax-free distributions.

Of course, recordkeeping matters here.

You want organized, digital copies of receipts, invoices, explanation of benefits statements, and proof of payment. A random pile of faded pharmacy receipts stuffed into a kitchen drawer next to expired takeout menus is probably not the system we’re aiming for.

What HSAs Can Actually Pay For

Most people know HSAs can cover deductibles, copays, prescriptions, and doctor visits. But the list of eligible expenses is often much broader than you might think.

Depending on the circumstances, HSA funds may be used for dental work, orthodontics, vision exams, LASIK surgery, hearing aids, physical therapy, chiropractic care, mental health counseling, fertility treatments, smoking cessation programs, CPAP machines, blood pressure monitors, orthopedic supports, and various forms of medical equipment.

Certain medically necessary home modifications may partially qualify as well, in some situations.

But this is also where we need to be careful.

One of the most common mistakes is assuming an item qualifies simply because it sounds health-related or because a company markets the product as “HSA eligible.”

Lately, there has been a major increase in fitness and recovery products advertising HSA compatibility. Things like Normatec compression systems, massage guns, recovery boots, specialized ergonomic products, and even certain exercise equipment are often marketed this way online.

In some cases, those expenses may absolutely qualify. But many of them require proper medical documentation, particularly a Letter of Medical Necessity (LMN) from a physician.

The IRS generally looks at whether the item is being used to treat or alleviate a diagnosed medical condition rather than simply improve general wellness or athletic performance.

That’s an important line to understand.

A physician prescribing specific equipment as part of rehabilitation after surgery or treatment for a chronic condition is very different from somebody trying to classify their garage gym as preventive medicine because deadlifts are technically healthy (a line of thinking I admittedly appreciate).

If that standard worked universally, half the country would be trying to reimburse golf memberships and pickleball paddles.

Before making larger purchases or assuming reimbursement eligibility, it’s smart to confirm requirements directly with your HSA provider or tax professional. Some HSA administrators have different documentation standards, and obtaining pre-approval or physician documentation ahead of time can help avoid reimbursement issues later.

Using an HSA for Insurance Premiums

One of the most overlooked uses for HSAs involves healthcare premiums themselves.

Under certain circumstances, HSA funds can be used tax-free for COBRA coverage, health insurance premiums during periods of unemployment, long-term care insurance within IRS limits, and Medicare-related healthcare expenses.

Someone retiring before Medicare eligibility may spend several years purchasing healthcare coverage through the Affordable Care Act marketplace. Having a pool of tax-free HSA dollars available to help cover deductibles and co-pays on these plans can create meaningful flexibility while managing taxable income and portfolio withdrawals during the early retirement years, especially if out-of-pocket expenses come up. I’m not one to speculate on what percentage of future healthcare costs individuals may ultimately bear two decades from now, but I will say that our family is planning with the assumption that we may need to shoulder more of that responsibility ourselves once we come off company healthcare plans.

Then after age 65, the HSA becomes even more useful.

HSA funds can generally be used tax-free for Medicare Part B premiums, Medicare Part D prescription drug plans, and Medicare Advantage premiums. One important exception is Medicare supplement policies, commonly referred to as Medigap plans, which generally are not considered qualified HSA expenses.

Still, for many retirees, healthcare becomes one of the largest ongoing expenses they face outside of housing. Having a dedicated pool of tax-advantaged dollars specifically earmarked for those costs can significantly improve retirement flexibility over time.
