Should You Pay for Hip Replacement with Your HSA - or Invest and Reimburse Later?

Hip Replacement typically costs $30,000
Range: $20,000 – $40,000. Here's how each strategy plays out.

The Verdict
For a $30,000 expense like Hip Replacement, the shoebox strategy wins if you can afford to pay out of pocket. By keeping that $30,000 invested in your HSA at 7% annual returns, you could earn an additional $29,015 over 10 years or $86,091 over 20 years - all tax-free.
You still get the same $9,000 tax deduction either way. The only difference is when you take it. Meanwhile, your HSA money compounds untouched.

30% combined tax rate
Federal + state income tax + FICA
Compounding annually
Actual returns will vary year to year
When to Pay with Your HSA Instead
The shoebox strategy is not for everyone. Paying directly with your HSA makes more sense when:
- You do not have cash on hand. If paying $30,000 out of pocket would strain your budget or emergency fund, use your HSA. That is what it is for.
- The amount is small. For expenses under $200-300, the potential investment growth may not be worth the effort of saving receipts and tracking reimbursements.
- You need the money now. If you are facing a financial emergency or carrying high-interest debt, preserving cash by using your HSA is the smarter move.
- You are not investing your HSA. The shoebox strategy only works if your HSA is invested. Money sitting in a savings account earning 0.1% does not benefit from deferral.
