What is one function of the CPT index for medical coding?

The function of the CPT index in medical coding is to identify main terms in boldface. This feature is particularly useful for coders as it allows them to quickly find relevant codes associated with specific medical terms or procedures. The bolding of main terms helps to emphasize important concepts, making navigation through the index more efficient.

While the CPT index does include alphabetical listings and may provide symbols and modifiers, its primary role is to serve as a quick reference guide that highlights key terms for coding, thereby facilitating easier retrieval of information. This distinction is crucial for coders who need to find correct procedural codes efficiently.
