Go to Charges from the main menu and choose Edit Charges.

Search for the Patient and select the Patient DOS.

Use the  button on corresponding CPT line.

Now, over the posting activity screen, enter the amount to be reversed under the PAID field.

Here we have two options, either to use the REVERSE or the REVERSE/REFUND button. The REVERSE/REFUND button should reverse the payment and take us to the refund screen where we could confirm and save the refund operation.

Another option is to use REVERSE button and later complete the refund transaction from Enter/Edit Payment screen.
