How FSA/HSA Spending Works
Save up to 30% on health-related purchases by using pre-tax dollars
What is FSA/HSA?
FSA (Flexible Spending Account)
Employer-sponsored account where you set aside pre-tax money for medical expenses. Funds typically expire at year-end (use it or lose it).
HSA (Health Savings Account)
Personal account for those with high-deductible health plans. Funds roll over year to year and can be invested.
How to Use Your Funds
1. Check Eligibility
Search for any product on CanIExpenseThis to see if it's FSA/HSA eligible. Products are either automatically eligible, conditionally eligible (needs LOMN), or not eligible.
Search now2. Get LOMN (If Needed)
For conditionally eligible items, you'll need a Letter of Medical Necessity from your doctor. This letter certifies the item is medically necessary for treating a specific condition.
We provide templates for every conditional item to make this easy.
3. Purchase & Submit
Buy the item using your FSA/HSA card directly, or pay out-of-pocket and submit for reimbursement. Keep your receipt and LOMN (if applicable) for your records.
4. Save Up to 30%
Because FSA/HSA funds are pre-tax, you effectively save your marginal tax rate on every purchase. For most people, that's 22-37% in federal taxes, plus state taxes.
What is a Letter of Medical Necessity (LOMN)?
A LOMN is a document signed by your doctor that certifies a product is medically necessary to treat, mitigate, or prevent a diagnosed medical condition. It's required for "conditional" items.
A valid LOMN must include:
- Your name and diagnosis (ICD-10 code)
- The specific product being prescribed
- How the product treats or helps manage your condition
- Doctor's signature, credentials, and contact info
Browse any conditional product on our site to get a customized LOMN template.
