0174Nature of Service/Test/Observation
Table of codes 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.
Values
| Value | Description |
|---|---|
A | Atomic service/test/observation (test code or treatment code) |
C | Single observation calculated via a rule or formula from other independent observations (e.g. Alveolar-arterial ratio cardiac output) |
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 |
P | Profile or battery consisting of many independent atomic observations (e.g. SMA12 electrolytes) usually done at one instrument on one specimen |
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 |
