Test/Observations Included within an Ordered Test Battery

Definition: This field contains the codes and names of all tests/observations included within a single battery (nature code P, as described in OM1-18 - Nature of service/test/observation), a single functional procedure (nature code F), or a given superset (nature code S). When a segment includes a list of component elements, the sending system should be sure that the segments defining all of the components are sent before the segment that references them. An entry in this list can itself be a battery.
