What it does not mean

The code identifies the observation or test, not the actual result.

Key facts

CT Head W contrast IV and CT Orbit - bilateral WO and W contrast IV

Multisection^W contrast IV && Multisection^WO & W contrast IV

This term represents a head CT with IV contrast performed in conjunction with a bilateral orbit CT without and with IV contrast. This is different from [LOINC82742-8], which represents a head CT without and with IV contrast performed in conjunction with a bilateral orbit CT with IV contrast.
