What is true about instructional notes in the Index and Tabular?

• A. They Must Be Read and Guide Code Selection
• B. They Can Be Ignored
• C. They Are Optional for Experienced Coders
• D. They Apply Only to Inpatient Coding

Answer: (C)

Instructional notes in the Index and Tabular are there to guide how you choose and sequence codes. They tell you when a condition must be coded first, when an additional code is needed for manifestations or severity, and how to handle exclusions or cross-references. Because these notes directly influence which code(s) you assign, they must be read and followed by coders at all levels and in all settings, not just for beginners or in one setting. They apply to inpatient and outpatient coding alike, and they’re not optional. In short, they provide essential direction for accurate code selection and reporting.
