Which volume of the ICD-10 code system is organized in chapters based on disease?

This organization allows healthcare professionals to efficiently locate and classify diagnoses in a systematic manner, facilitating accurate coding for billing, reporting, and statistical purposes. Each chapter of Volume 1 focuses on a specific category of diseases, such as infectious diseases, cancers, or respiratory conditions, making it easier for coders and medical practitioners to navigate through the various codes as they relate to specific medical conditions.
