You may need to refund the patient after the 90-day refund window has closed. When this happens, you can cut a check to the patient and mark the invoice in Hint as externally refunded via check. Please see the below on how to do so:
Navigate to the invoice where you are processing the refund
Click 'Process Refund'
Select 'Check' or 'Other'
As a note, you are responsible for refunding the patient outside of the Hint platform.
Once you select the refund method, you can input a memo for revision and process refund
