What are ICD-10 Codes?
ICD-10 refers to the tenth edition of the International Classification of Diseases, which is a medical coding system chiefly designed by the World Health Organization (WHO) to catalog health conditions by categories of similar diseases under which more specific conditions are listed, thus mapping nuanced diseases to broader morbidities.
ICD-10 codes used for medical claim reporting in all healthcare settings. ICD-10 is a standardized classification system of diagnosis codes that represent conditions and diseases, related health problems, abnormal findings, signs and symptoms, injuries, external causes of injuries and diseases, and social circumstances. For a medical provider to receive reimbursement for medical services, ICD-10-CM codes are required to be submitted to the payer. While CPT® codes depict the services provided to the patient, ICD-10 codes depict the patient’s diagnoses that justify the services rendered as medically necessary.
