What is ICD-10-CM?
ICD-10-CM (International Classification of Diseases, 10th Revision, Clinical Modification) is the U.S. standard for diagnosis codes used in medical billing, quality reporting, and clinical documentation. Each code maps to a condition or reason for encounter; many codes indicate whether they are billable on a claim.
