Which coding system codes inpatient procedures?

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

Answer: (B)

Inpatient procedures are coded with ICD-10-PCS, a system created specifically for describing hospital procedures performed during an inpatient stay. It uses detailed seven-character codes that capture the procedure, body part, approach, device, and qualifiers. CPT is used for outpatient procedures and professional services, ICD-10-CM handles diagnoses, and HCPCS Level II covers non-wac itemized codes like supplies and equipment. So for the hospital inpatient setting, ICD-10-PCS is the appropriate coding system.
