Table 0174 - Nature of Service/Test/Observation
5 coded values. Used by OM1-18.
| Code | Meaning |
|---|---|
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 |
