Diseases – Sorted by ICD-10

Clarity first: All categories are strictly organized according to the chapters of ICD-10—the International Classification of Diseases. As a diagnostic code and catalog of acute and chronic, congenital and acquired diseases, this code is valid worldwide.

Every medical finding can be precisely described using an ICD-10 code: What is affected? What is the cause of the disease or injury? How severe are the symptoms? Here you’ll find all disease categories—from respiratory and circulatory systems, muscles and bones, to the digestive system and injuries.
