Code system of concepts specifying an identification of a test battery, an entire functional procedure or study, a single test value (observation), multiple test batteries or functional procedures as an orderable unit (profile), or a single test value (observation) calculated from other independent observations, typically used as an indicator for Master Files. Used in HL7 Version 2.x messaging in the OM1 segment.

Superset—a set of batteries or procedures ordered under a single code unit but processed as separate batteries (e.g., routines = CBC, UA, electrolytes) This set indicates that the code being described is used to order multiple service/test/observation batteries. For example, a client who routinely orders a CBC, a differential, and a thyroxine as an outpatient profile might use a single, special code to order all three test batteries, instead of having to submit three separate order codes.

can be associated with one or more OM4 (specimen) segments Codes P, F, and S identify sets (batteries) and should be associated with an OM5 segment that defines the list of elements. The definitions for the contained elements would have to be sent in other independent OMx segments, one for each contained element. In the ASTM context, most text reports – such as discharge summaries, admission H&Ps, and chest X-ray reports – are considered as sets, in which each section of the report (e.g., description, impression, and recommendation of an X-ray report) is considered a separate observationcan be associated with one or more OM4 (specimen) segments Codes P, F, and S identify sets (batteries) and should be associated with an OM5 segment that defines the list of elements.
