Frequently asked questions

Will my treadmill actually be reimbursed?

An LMN documents medical necessity, then Burst files your reimbursement for you. Final approval is determined by your plan administrator, the same as any other eligible expense.

Does a treadmill qualify without a letter?

Home fitness equipment generally needs a Letter of Medical Necessity to be FSA/HSA eligible. Burst gets you a clinician-reviewed letter, usually the same day.

How fast do I get my letter?

Intake takes under two minutes and your letter is issued the same day in most cases.

Which FSA/HSA plans does this work with?

Burst works with every FSA/HSA admin.

Do I need my own doctor?

No. A licensed clinician in the Burst network reviews your information and issues the letter. You do not need an existing relationship with a provider.

What if my plan denies the claim?

Reimbursement is decided by your plan administrator. If a clinician determines an LMN is not appropriate for you, your $25 is refunded automatically. We also refund you if your claim is denied because of the LMN.
