This action is specifically related to handling a nonsufficient funds (NSF) check. When a check bounces due to insufficient funds in the payer's account, the previously recorded payment must be reversed. This is done by adding the amount of the check back into the patient's account as if the payment was never made, which is accurately described by the process for handling a nonsufficient funds check.
