ICD-10, or the International Classification of Diseases, 10th Revision, is a coding system used by healthcare providers to classify and document diseases, conditions, and other health-related issues. Developed by the World Health Organization (WHO), it provides a standardized way to record diagnoses, which helps in research, billing, and health statistics. The ICD-10 system includes codes for a wide range of health conditions, from infectious diseases to injuries and chronic illnesses. Each code consists of alphanumeric characters, allowing for detailed categorization. This system is essential for improving patient care and facilitating communication among healthcare professionals globally.
