About 04L00CZ

04L00CZ is the ICD-10-PCS code for a occlusion procedure on the abdominal aorta using an open approach with extraluminal device. In ICD-10-PCS, occlusion means completely closing an orifice or the lumen of a tubular body part.

In plain terms, this corresponds to other surgical occlusion of vessels, aorta, abdominal, the ICD-9-CM procedure title it maps to (38.84).

The same procedure with a different approach is coded 04L03CZ (percutaneous) and 04L04CZ (percutaneous endoscopic).

With a different device, use 04L00DZ (intraluminal device) and 04L00ZZ (no device).
