Table 0174: Nature 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.

Codes
| Code | Meaning | Definition |
|---|---|---|
P | Profile or battery consisting of many independent atomic observations (e.g., SMA12, electrolytes), usually done at one instrument on one specimen | |
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 | |
A | Atomic service/test/observation (test code or treatment code) | |
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 | 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. |
C | Single observation calculated via a rule or formula from other independent observations (e.g., Alveolar-arterial ratio, cardiac output) |

Elements with a dot (such as CX.5) are data type components, used wherever that data type appears.
