ICD-10-PCS Body System: ICD-10-PCS Body System 0W - Anatomical Regions, General

Within the ICD-10-PCS Medical and Surgical section, the root operations under the General Anatomical Regions classification (0W) encompass a variety of procedures involving manipulation of body parts without limiting to a specific organ or system.

The 0W code group includes diverse root operations such as Alteration (0W0), which modifies an anatomical structure without changing its function, and Bypass (0W1), which alters the passage route inside a tubular body part. Other important operations include Inspection (0WJ) for visual or manual examination, Insertion (0WH) of non-biological appliances supporting physiological functions, and Repair (0WQ) aimed at restoring normal anatomy and function. Additionally, codes cover procedures like Drainage (0W9), Excision (0WB), and Transplantation (0WY), each targeting specific clinical goals. These key ICD-10-PCS root operations enable precise coding of procedures affecting general anatomical regions, supporting accurate clinical documentation and billing across multiple surgical interventions.
