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

ICD-10-PCS, or the International Classification of Diseases, Tenth Revision, Procedure Coding System, is designed specifically for coding and classifying procedures performed in inpatient hospital settings. This system provides a comprehensive classification of surgical and diagnostic procedures that are conducted during a hospital stay.

The primary focus is on procedure data, which means it is utilized exclusively for inpatient settings where patients undergo procedures that require an elevated level of care, often involving higher complexities that differentiate them from outpatient or ambulatory settings. Each code in the ICD-10-PCS system reflects a specific intervention or procedure performed during the patient's inpatient care.

In contrast, options relating to ambulatory records, outpatient records, and patient demographic data do not fall under the purview of ICD-10-PCS. Ambulatory and outpatient care is typically coded using different systems, such as Current Procedural Terminology (CPT), which is suited for services provided that do not require an overnight hospital stay. Similarly, patient demographic data is not part of procedural coding and instead involves information related to the patient's identification and characteristics. This delineation solidifies the appropriateness of the correct answer, emphasizing ICD-10-PCS's dedicated role in inpatient procedure coding.
