Medical Coding Practice Test

Which volume of ICD-9-CM contains the Alphabetic Index?

1. Volume One

2. Volume Two

3. Volume Three

4. Volume Four

The correct answer is: Volume Two

Volume Two of the ICD-9-CM contains the Alphabetic Index. This volume is crucial for medical coders as it lists codes in an alphabetical order by diseases, conditions, and terms, providing a convenient way to look up codes based on the diagnosis or condition. Volume One contains the Tabular List of the ICD-9-CM, Volume Three includes procedures, and Volume Four is the Tabular List and Alphabetic Index of Procedures. Having access to the Alphabetic Index in Volume Two allows medical coders to efficiently find the appropriate codes for diagnoses encountered during medical coding and billing processes.
