Nature of Service/Test/Observation
2015-07-13
Definition: This field indicates whether the definition entry identifies 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. Refer to User-defined Table 0174 - Nature of Service/Test/Observation in Chapter 2C, Code Tables, for suggested values.

A | Atomic service/test/observation (test code or treatment code)(can be associated with one or more OM4 (specimen) segments<p>a single direct observation and would usually be associated with an OM2 and/or OM3 segments) |
C | Single observation calculated via a rule or formula from other independent observations (e.g., Alveolar-arterial ratio, cardiac output)(can be associated with one or more OM4 (specimen) segments<p>a derived quantity and would usually be associated with an OM6 segment) |
F | Functional procedure that may consist of one or more interrelated measures (e.g., glucose tolerance test, creatinine clearance), usually done at different times and/or on different specimens(can be associated with one or more OM4 (specimen) segments<p>See comment for value S) |
P | Profile or battery consisting of many independent atomic observations (e.g., SMA12, electrolytes), usually done at one instrument on one specimen(can be associated with one or more OM4 (specimen) segments<p>See comment for value S) |
S | Superset-a set of batteries or procedures ordered under a single code unit but processed as separate batteries (e.g., routines = CBC, UA, electrolytes)<p>This set indicates that the code being described is used to order multiple service/test/observation b(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 observation) |
