Once your Letter of Medical Necessity (LMN) arrives by email, you can get reimbursed from your FSA or HSA for the purchase. You have two options.

Option 1: Let Burst file it for you

For a small fee, Burst files the claim with your FSA/HSA administrator for you. Funds typically land in your bank account within 1 to 3 days.

Upload your receipt

Add a photo or PDF of your receipt. Burst scans it and matches the item to your letter.

Confirm and submit

Check the details, review the fee, and submit. You can track the reimbursement in your Burst account.

Option 2: File it yourself

Find your FSA/HSA administrator

It’s usually the company named on your FSA/HSA card, or the benefits portal your employer pointed you to. Not sure? Ask your HR team.

Log in to their portal or app

Look for a section called Reimbursement, Claims, or Submit a claim.

Upload your LMN and receipt

Submit both documents. Some administrators take PDFs; others prefer photos through their mobile app.

Wait for approval

Processing times vary by administrator, from a few business days to a few weeks. Once approved, the money is deposited to you or applied to your balance.

Reuse your letter

Your letter covers future purchases from the same store for 12 months from the day you requested it. Keep a copy handy and file each new receipt the same way.

A letter can’t be backdated. It covers purchases made on or after the day you requested it, not before.

Burst can’t guarantee how an administrator will decide any individual claim.
