What Can I Use FSA with HSA Rules? Understanding the Guidelines for Healthcare Spending Accounts

If you have both a Flexible Spending Account (FSA) and a Health Savings Account (HSA), it's important to understand how you can use them in accordance with the rules. Each account has its own set of guidelines and restrictions, and knowing the differences can help you maximize your healthcare spending benefits. Here's a breakdown of what you need to know:

Using FSA with HSA Rules:

  • Prescription Medications: Both FSA and HSA can typically be used to cover the cost of prescription medications.
  • Over-the-Counter (OTC) Medications: FSA funds can be used for OTC medications without a prescription, but as of 2020, HSA funds require a doctor's prescription for OTC purchases.
  • Medical Supplies: FSA and HSA can generally be used for medical supplies like bandages, crutches, and more.
  • Doctor Visits: Both accounts can cover co-pays, deductibles, and other out-of-pocket costs for doctor visits.

It's important to note that IRS regulations dictate what expenses are eligible for FSA and HSA reimbursement. Be sure to keep receipts and documentation for all healthcare expenses to ensure compliance with the rules.


When navigating your healthcare expenses, understanding how to effectively use both a Flexible Spending Account (FSA) and a Health Savings Account (HSA) can help you get the most out of your benefits.
