Understanding Sub-Field Delimiters |
 | ||
|
Sub-Field Delimiters Sub-fields in a composite are delimited with a sub-field delimiter (^ in HL7). HL7 empty fields must still be represented with a place holder by outputting consecutive delimiter characters. For any sub-field that is empty, two subsequent delimiters will appear. | ||

Consider the following example:
33 WEST BURTON COURT^^CHICAGO^IL^98052^USA |
The above Patient Address field has six sub-fields:
Patient Address Field, Showing Six Sub-Fields
Since Field 2 - Other Designation is empty, it is represented by two consecutive delimiter characters.
