Which coding system is specifically used for inpatient procedures?

The coding system specifically used for inpatient procedures is ICD-10-PCS (International Classification of Diseases, 10th Revision, Procedure Coding System). This system was developed for the purpose of capturing procedure information for inpatient hospital settings, and it is utilized primarily in the United States. ICD-10-PCS contains a comprehensive set of codes that precisely describe surgical and other procedures performed during an inpatient stay, allowing for accurate billing and data collection within the healthcare system.

The structure of ICD-10-PCS codes is unique, incorporating seven alphanumeric characters that provide detailed information about the procedure, including the section, body system, root operation, body part, approach, device, and qualifier. This level of granularity is necessary for effective management of inpatient services and for fulfilling reporting requirements for healthcare facilities.

In contrast, the other coding systems mentioned serve different purposes or settings. For instance, the CCS (Clinical Classifications Software) is used for grouping ICD codes into clinically meaningful categories, while ICD-10-CM (Clinical Modification) is primarily intended for outpatient coding. HCPCS (Healthcare Common Procedure Coding System) includes codes for services not covered by the CPT (Current Procedural Terminology) codes and primarily pertains to outpatient and non-physician services.
