Where is specific coding information about each section located?

The correct choice is indeed the guidelines that are at the beginning of each section, as they provide essential coding information tailored to the specific group of codes you’ll be working with. These guidelines include important instructions, definitions, and recommendations that help clarify how to apply the coding in practice. They outline pertinent details such as the correct use of codes, coding conventions, and any additional notes that can aid in accurate coding.

In contrast, the end of the manual typically contains summary information, while the index serves as a navigational tool for locating codes but does not provide detailed guidance on coding specifics. Appendices may contain supplementary information or additional resources, but do not detail coding instructions for each section like the guidelines do.
