Notes:

1. Trace numbers assigned at the subscriber level are intended to allow tracing of an eligibility/benefit transaction when the subscriber is the patient.
2. The information receiver may assign one TRN segment in this loop if the subscriber is the patient. A clearinghouse may assign one TRN segment in this loop if the subscriber is the patient. See Section 1.3.6 Information Linkage.
