What documentation do FSA and HSA administrators usually need?
An itemized receipt showing the date, provider or merchant, service or product, and amount, plus an LMN when the expense is not clearly medical.
A card statement alone is often not enough because it does not show what was purchased. Administrators typically want the itemized detail.
A complete package, with the receipt, provider details, and any required letter, helps avoid requests for more information.
Pending clinician sign-off. General education only, not medical, tax, or legal advice. Your plan administrator decides eligibility.
