Medical Coding Practice Test

How many volumes does ICD-9-CM contain?

1. One

2. Two

3. Three

4. Four

The correct answer is: Three

ICD-9-CM (International Classification of Diseases, 9th Revision, Clinical Modification) contains three volumes Volume 1 - Tabular List, Volume 2 - Instruction Manual, and Volume 3 - Alphabetical Index. These volumes provide specific coding guidelines and instructions for medical diagnoses and procedures. Option A is incorrect because ICD-9-CM is not just one book, but three separate volumes. Option B is incorrect because while there are technically two books (a tabular list and an index), there is also an instruction manual included in the set. Option D is incorrect because ICD-9-CM does not contain four volumes, only three.
