I used my card. Why Do I Need to Submit Documentation?

How to submit documentation for an Ameriflex Debit Mastercard transaction.

You've just received a notification that a card transaction for your Ameriflex Debit Mastercard needs additional documentation. We'll briefly explain the reason why and how you can clear it.  

If you've swiped your card and the transaction cannot be auto-verified at the point of purchase, this is normally because the merchant’s (e.g. hospital) payment terminal can’t distinguish if the transaction was for an eligible expense (e.g. surgery) or an ineligible expense (e.g. flowers from the hospital gift store). 

Note: The IRS requires all claims, including debit card transactions, to be substantiated to verify eligibility under the tax code. Successful verification allows you to enjoy the tax benefits associated with flexible spending accounts and health reimbursement arrangements. You will receive a notification from Ameriflex requesting additional documentation from you if we can't auto-verify the expense.  

If Ameriflex cannot auto-verify your expense, you will receive a notification prompting you to log in to your account and provide additional documentation for the transaction, such as an itemized receipt, Explanation of Benefits (EOB), or a letter of medical necessity.
