FAQ: What is the difference between ICD-10-PCS codes and ICD-10-CM codes?
ICD-10-CM codes are diagnosis codes. They are defined globally by the World Health Organization (WHO), but are modified for use in the United States by the National Center for Health Statistics (NCHS). Most professional, outpatient and ambulatory practices will use ICD-10-CM codes.
By contrast, ICD-10-PCS codes are procedure codes. These codes are created by the Centers for Medicare and Medicaid Services (CMS) and are only used on inpatient, facility-based claims. Ambulatory practices will continue to use CPT procedure codes, just as they do now, when ICD-10 takes effect.
