What You Need to Know About
ICD-10
ICD-10 is a diagnostic coding system created by the World Health Organization (WHO) in the late 1990’s. It was intended to replace ICD-9 in order to more accurately capture diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases. The ICD-10 is significant because the new code system will allow for better analysis of disease patterns and treatment outcomes, which will theoretically advance medical care.
NUMBER OF CODES
ICD-10 will have over 68,000 codes versus the 13,000 currently in use for ICD-9
COMBINATION CODES
