What does a “parenthetical note” in the CPT manual signify?

A parenthetical note in the CPT manual provides additional information or instructions related to a specific code. These notes can clarify the definition of a procedure, indicate when certain codes should or should not be used, or provide helpful context that ensures accurate coding. They are essential for coders as they contain vital details that enhance understanding and proper application of the codes.

While a mandatory coding instruction may be presented in the CPT manual, this is typically found in specific sections or guidelines without the use of parentheses. Other formats, such as standalone statements, may indicate mandatory requirements. The section for frequently asked questions is usually not represented as a parenthetical note but rather contained in separate guidance or instructional materials. Moreover, examples of how to use the code may be provided in different areas of the manual but are not specifically indicated by parenthetical notes, which focus on supplemental information rather than explicit examples.
