ICD-10-CM Volumes 1 and 2 are associated with coding diagnoses, signs, and symptoms.

ICD-10-CM Volumes 1 and 2 are associated with coding diagnoses, signs, and symptoms.

• A. Volumes 1 and 2
• B. Volume 3
• C. All volumes
• D. None

Answer: (A)

In ICD-10-CM, diagnosing codes (including codes for signs and symptoms) are organized into two volumes: the Alphabetic Index and the Tabular List. The Alphabetic Index guides you to a set of candidate codes, and the Tabular List provides the official codes with their full descriptions to verify the correct one. Volume 3, by contrast, is used for ICD-10-PCS procedural coding, not diagnoses. So the statement that diagnosing codes come from the first two volumes is accurate. The other options don’t fit because Volume 3 isn’t for diagnoses, and saying all volumes or none would misstate how ICD-10-CM is structured.
