What does the prefix "Ab-" indicate in terms of location?

1. Away from

2. Toward; near

3. Through; complete

4. After

The correct answer is: Away from

The prefix "Ab-" is used in medical terminology to denote a location that is "away from" a specific reference point. For example, in anatomical terms, when describing structures or conditions in the body, "abduct" refers to moving a limb away from the midline of the body. This prefix helps clarify the direction or relationship of body parts in relation to one another. Understanding prefixes like "Ab-" is crucial for medical coders, as it aids in accurately interpreting medical terminology, which can affect coding decisions and documentation. Being familiar with such prefixes enhances one’s capability to effectively communicate and decode various medical reports, contributing to better clinical documentation and coding practice.
