ICD Codes, or International Classification of Diseases codes, are a standardized system used by healthcare providers to classify and code diagnoses, symptoms, and procedures. These codes help in documenting patient information, facilitating billing, and conducting health statistics. The codes are maintained by the World Health Organization (WHO) and are updated periodically to reflect new medical knowledge. The current version, known as ICD-10, includes thousands of codes that cover a wide range of health conditions. Each code consists of alphanumeric characters that provide specific information about a patient's diagnosis, allowing for better communication among healthcare professionals and improving patient care.
