About the 04N Code Range

The ICD-10-PCS root operation Release (Code 04N) involves freeing a body part from abnormal constraint by cutting or otherwise removing the restricting tissue. This operation is performed within the Medical and Surgical section and typically targets arteries to restore their normal function.

Release in the context of arteries focuses on removing obstructions or adhesions that limit blood flow. The provided codes cover various lower arteries, such as the Abdominal Aorta, Celiac Artery, Hepatic Artery, and peripheral arteries like the Femoral and Popliteal Arteries. Approaches include Open, Percutaneous, and Percutaneous Endoscopic, reflecting different procedural techniques. For example, code 04N00ZZ denotes an open approach release of the Abdominal Aorta, while 04N34ZZ describes a percutaneous endoscopic release of the Hepatic Artery. These detailed artery release codes ensure precise clinical documentation when alleviating vascular constraints.
