What does the semicolon of a cpt entry mean?

In a Current Procedural Terminology (CPT) entry, a semicolon indicates that the code following it is a component of a more comprehensive procedure described before the semicolon. This means that the specific procedure is part of a larger set of related services, and the description after the semicolon provides additional detail about the specific aspects or variations of the primary procedure. It helps to streamline coding by allowing multiple related procedures to be grouped together under a single code.
