Introduction

ICD-10-CM (the International Classification of Diseases, Tenth Revision, Clinical Modification) is a standardized system used to code diseases and medical conditions (morbidity) data. Healthcare providers use ICD-10-CM codes when diagnosing patients. ICD-10-CM builds on ICD-10 (the International Classification of Diseases, Tenth Revision)— the system used to code causes of death on death certificates.

CDC's National Center for Health Statistics (NCHS) is responsible for the clinical modification of ICD-10 for use in the United States. The , which owns and publishes ICD-10, authorized NCHS to develop ICD-10-CM. All modifications to ICD-10 must conform to WHO's established ICD structure and conventions.
