The US inpatient procedure coding system, developed by CMS. Required for every procedure on inpatient hospital claims. Over 78,000 seven-character alphanumeric codes, where each character position has a distinct classification axis covering surgical, imaging, and therapeutic procedures. Use alongside ICD-10-CM for diagnosis coding. For outpatient procedures, use CPT instead.
