Frequently Asked Questions

Important Note on Letters of Medical Necessity (LMN)

BuyFSA defines "FSA-approved expenses" as those where an FSA Card can transact the expense without the need for further documentation. Ineligible expenses may be approved with a doctor's note if there is a medical need. However, every FSA administrator has different auditing rules that often complicate the process for reimbursement. BuyFSA only lists guaranteed FSA-approved products and services that do not require additional LMN documentation.
