About 04R04KZ

04R04KZ is the ICD-10-PCS code for a replacement procedure on the abdominal aorta using a percutaneous endoscopic approach with nonautologous tissue substitute. In ICD-10-PCS, replacement means putting in or on biological or synthetic material that physically takes the place and/or function of all or a portion of a body part.

In plain terms, this corresponds to resection of vessel with replacement, aorta, abdominal, the ICD-9-CM procedure title it maps to (38.44).

For a different body part, codes include 04R14KZ (celiac artery), 04R24KZ (gastric artery), 04R34KZ (hepatic artery), 04R44KZ (splenic artery), 04R54KZ (superior mesenteric artery), 04R64KZ (right colic artery) and 24 more.

The same procedure with a different approach is coded 04R00KZ (open).

With a different device, use 04R047Z (autologous tissue substitute) and 04R04JZ (synthetic substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 268 (Aortic and Heart Assist Procedures Except Pulsation Balloon with MCC), DRG 269 (Aortic and Heart Assist Procedures Except Pulsation Balloon without MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC), DRG 909 (Other O.R. Procedures for Injuries without CC/MCC) and DRG 957 (Other O.R. Procedures for Multiple Significant Trauma with MCC), under the surgical categories “Aortic and Heart Assist Procedures Except Pulsation Balloon”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

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