Which code set is used primarily for procedures in hospital inpatient settings?

• A. CPT
• B. ICD-9-CM
• C. ICD-10-PCS
• D. HCPCS

Answer: (C)

Procedures performed during a hospital stay are coded with ICD-10-PCS because it's the dedicated inpatient procedure coding system. ICD-10-PCS uses seven-character alphanumeric codes designed to describe the exact procedure, including the body system, the approach, any devices used or implanted, and other qualifiers. This detail is essential for inpatient billing, reporting, and data analysis in acute care settings. CPT codes are used mainly for professional services and many outpatient procedures performed by physicians. HCPCS covers supplies, equipment, and certain services not included in CPT. ICD-9-CM is an older system that preceded ICD-10-PCS for inpatient procedures and has largely been replaced. Thus, for hospital inpatient procedures, ICD-10-PCS is the appropriate code set.
