About 05V04ZZ
05V04ZZ is the ICD-10-PCS code for a restriction procedure on the azygos vein using a percutaneous endoscopic approach. In ICD-10-PCS, restriction means partially closing an orifice or the lumen of a tubular body part.
In plain terms, this corresponds to other repair of aneurysm, the ICD-9-CM procedure title it maps to (39.52).
For a different body part, codes include 05V14ZZ (hemiazygos vein), 05V34ZZ (right innominate vein), 05V44ZZ (left innominate vein), 05V54ZZ (right subclavian vein), 05V64ZZ (left subclavian vein), 05V74ZZ (right axillary vein) and 19 more.
The same procedure with a different approach is coded 05V00ZZ (open) and 05V03ZZ (percutaneous).
With a different device, use 05V04CZ (extraluminal device) and 05V04DZ (intraluminal device).
It is an operating-room procedure in the MS-DRG logic for DRG 270 (Other Major Cardiovascular Procedures with MCC), DRG 271 (Other Major Cardiovascular Procedures with CC), DRG 272 (Other Major Cardiovascular Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Other Major Cardiovascular Procedures” and “Other O.R. Procedures for Injuries”.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
