Final answer:
For codes related to an appendectomy, refer to the 'Surgery' section of the medical coding manual, such as CPT. Appendectomies are surgical procedures, hence the relevance of this section.
Step-by-step explanation:
If you are looking for codes related to an appendectomy (removal of the appendix), the correct section to refer to is the "Surgery" section. Appendectomies are surgical procedures, and thus the codes are categorized under this section. Medical coding, such as the codes found in the Current Procedural Terminology (CPT) manual, provides a uniform language for reporting medical services and procedures. The surgery section in these manuals includes codes for all the different surgical procedures grouped according to the body system or anatomical site.
