How many volumes are included in the ICD-10 coding system?

The ICD-10 coding system consists of three main volumes, which is why the choice indicating three volumes is the correct answer.

The first volume contains the Tabular List of Diseases and Injuries, which includes the codes and rules for accurate coding. The second volume consists of the Alphabetic Index, which allows coders to look up diagnoses by keywords. The third volume is dedicated to procedures and contains code references for surgical and other procedures.

Understanding the structure of the ICD-10 is crucial for efficient coding and billing processes in the healthcare field, as it outlines the organization and uses of the codes that are essential for healthcare documentation and reimbursement.
