ICD-10-PCS is used to code what type of data?

• A. Inpatient setting.
• B. Outpatient clinics.
• C. Pharmacy benefit management.
• D. Home health services.

Answer: (A)

ICD-10-PCS is a procedure coding system used specifically for hospital inpatient procedures. It is designed to capture the work performed during an inpatient stay and is used for billing and data collection tied to that admission. This code set is not used for outpatient services, pharmacy management, or home health services, which rely on CPT/HCPCS or other coding schemes. Diagnoses in ICD-10-CM, not ICD-10-PCS, cover the patient’s condition, while the inpatient procedures themselves are coded with ICD-10-PCS. For example, a gallbladder removal done during an inpatient admission would be coded with ICD-10-PCS, whereas the same procedure in an outpatient setting would use CPT codes.
