Placeholder Table Representation

Used as a 'placeholder' in the several datatypes for any table (may be external, local, or may vary). If the field is of data type CQ, CE, CF, CNE or CWE and one or more externally or locally defined tables may be used, the number 9999 will appear as a placeholder for the actual table in the segment table column. This is to indicate that table values are used, but no HL7/User-defined table has been allocated. The narrative may constrain which external tables can be used.
