What is major diagnosis category?

Major diagnosis categories are groupings of medical conditions based on the classification system used by healthcare professionals. The most commonly used classification system is the International Classification of Diseases (ICD) maintained by the World Health Organization (WHO).

There are 21 major diagnosis categories recognized by the ICD, including infectious and parasitic diseases, neoplasms (cancer), endocrine, nutritional, and metabolic diseases, mental and behavioral disorders, diseases of the nervous system, circulatory system, respiratory system, digestive system, and musculoskeletal system, among others.

These categories help to organize and group medical conditions based on their symptoms, causes, and treatments. This classification system also makes it easier for healthcare professionals to communicate and share information about a patient's diagnosis and treatment plan.

Understanding major diagnosis categories is important for healthcare professionals to accurately diagnose and treat patients. It is also helpful for patients to understand their own medical conditions and to communicate effectively with their healthcare providers.
