About 05V04CZ

05V04CZ is the ICD-10-PCS code for a restriction procedure on the azygos vein using a percutaneous endoscopic approach with extraluminal device. In ICD-10-PCS, restriction means partially closing an orifice or the lumen of a tubular body part.

In plain terms, this corresponds to Clipping of aneurysm, the ICD-9-CM procedure title it maps to (39.51).

For a different body part, codes include 05V14CZ (hemiazygos vein), 05V34CZ (right innominate vein), 05V44CZ (left innominate vein), 05V54CZ (right subclavian vein), 05V64CZ (left subclavian vein), 05V74CZ (right axillary vein) and 19 more.

The same procedure with a different approach is coded 05V00CZ (open) and 05V03CZ (percutaneous).

With a different device, use 05V04DZ (intraluminal device) and 05V04ZZ (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 252 (Other Vascular Procedures with MCC), DRG 253 (Other Vascular Procedures with CC) and DRG 254 (Other Vascular Procedures without CC/MCC), under the surgical category “Other Vascular Procedures”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
