            If the 278 notification transaction passes through more than one clearinghouse, the second (and subsequent) clearinghouse may choose one of the following options: If the second or subsequent clearinghouse needs to assign their own TRN segment they may replace the received TRN segment belonging to the sending clearinghouse with their own TRN segment. Upon returning a 278 acknowledgment to the sending clearinghouse, they must remove their TRN segment and replace it with the sending clearinghouse's TRN segment. If the second or subsequent clearinghouse does not need to assign their own TRN segment, they should merely pass all TRN segments received in the 278 acknowledgment transaction.
            If the 278 notification passes through a clearinghouse that adds their own TRN in addition to an information source TRN, the clearinghouse will receive an acknowledgment from the information receiver containing two TRN segments that contain the value "2" (Referenced Transaction Trace Number) in TRN01. If the information receiver has assigned a TRN, the information receiver's TRN will contain the value "1" (Current Transaction Trace Number) in TRN01. If the clearinghouse chooses to pass their own TRN values to the information source, the clearinghouse must change the value in their TRN01 to "1" because, from the information source's perspective, this is not a referenced transaction trace number.
            Required when this loop is returned and the notification contained a tracking number at this level on the notification, or if the receiver or clearinghouse assigns a trace number to this patient event in the acknowledgment for tracking purposes.

               Any trace numbers provided at this level on the notification must be returned by the information receiver at this level of the 278 acknowledgment response if one is returned.
               If the 278 notification transaction passes through more than one clearinghouse, the second (and subsequent) clearinghouse may choose one of the following options: If the second or subsequent clearinghouse needs to assign their own TRN segment they may replace the received TRN segment belonging to the sending clearinghouse with their own TRN segment. Upon returning a 278 acknowledgment to the sending clearinghouse, they must remove their TRN segment and replace it with the sending clearinghouse's TRN segment. If the second or subsequent clearinghouse does not need to assign their own TRN segment, they should merely pass all TRN segments received in the 278 notification in the 278 acknowledgment response transaction.
               Required when this loop is returned and the notification contained a tracking number at this level on the notification, or if the receiver or clearinghouse assigns a trace number to this patient event in the acknowledgment for tracking purposes.

                      Required when this service level is returned and any trace numbers were provided at this level on the notification, or if the information receiver or clearinghouse assigns a trace number to this service in the acknowledgment for tracking purposes. If not required by this implementation guide, do not send.
                      Any trace numbers provided at this level on the notification must be returned by the information receiver at this level of the 278 notification.
                      If the 278 notification transaction passed through more than one clearinghouse, the second (and subsequent) clearinghouse may choose one of the following options: If the second or subsequent clearinghouse needs to assign their own TRN segment they may replace the received TRN segment belonging to the sending clearinghouse with their own TRN segment. Upon returning a 278 acknowledgment to the sending clearinghouse, they must remove their TRN segment and replace it with the sending clearinghouse's TRN segment. If the second or subsequent clearinghouse does not need to assign their own TRN segment, they should merely pass all TRN segments received in the 278 acknowledgment transaction.
                      If the 278 notification passed through a clearinghouse that adds their own TRN in addition to the information source's TRN, the clearinghouse will receive an acknowledgment from the information source containing two TRN segments that contain the value "2" (Referenced Transaction Trace Number) in TRN01. If the information source has assigned a TRN, the information source's TRN will contain the value "1" (Current Transaction Trace Number) in TRN01. If the clearinghouse chooses to pass their own TRN values to the acknowledgment's information receiver, the clearinghouse must change the value in their TRN01 to "1" because, from the information receiver's perspective, this is not a referenced transaction trace number.
