About 04RB0KZ

04RB0KZ is the ICD-10-PCS code for a replacement procedure on the inferior mesenteric artery using an open 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, abdominal arteries, the ICD-9-CM procedure title it maps to (38.46).

For a different body part, codes include 04R00KZ (abdominal aorta), 04R10KZ (celiac artery), 04R20KZ (gastric artery), 04R30KZ (hepatic artery), 04R40KZ (splenic artery), 04R50KZ (superior mesenteric artery) and 24 more.

The same procedure with a different approach is coded 04RB4KZ (percutaneous endoscopic).

With a different device, use 04RB07Z (autologous tissue substitute) and 04RB0JZ (synthetic substitute).

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”, “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.
