C001 Composite Unit of Measure
To identify a composite unit of measure (See Figures Appendix for examples of use.)
Figures Appendix
Usage
The structure of composite data element C001 permits reporting a unit of measurement that does not appear in the DE355 code list, but is composed of entries from the DE355 code list. For example, if DE355 does not contain a code for “pounds per square foot,” but does contain codes for “pound” and “foot,” the composite data element C001 permits the reporting of “pounds per square foot” without requesting an addition to DE355. Therefore, use of this composite data element structure reduces the need for additional codes in DE355.
For codes already existing in DE355, composite data element C001 equates to DE355 and no subelement delimiter is used.
Defaults
If not specified, the value of the exponent defaults to 1. If not specified, the value of the multiplier defaults to 1.
Examples
The following examples are current DE355 codes. If these codes had not already existed, C001 could have been utilized, instead, as follows:
