Which statement describes ICD-10-CM?

ICD-10-CM is the diagnosis coding system used in U.S. health care to document diseases and other health conditions for patient records and insurance claims. This makes it primarily used for billing diagnoses, translating the clinician’s documented conditions into standardized codes that justify medical necessity and determine reimbursement. While these codes also support epidemiology and health statistics, the central role is coding diagnoses for billing. Codes for clinical labs are typically handled by other systems (like LOINC for lab values) and scheduling isn’t done with ICD-10-CM codes.
