About 04RB47Z

04RB47Z is the ICD-10-PCS code for a replacement procedure on the inferior mesenteric artery using a percutaneous endoscopic approach with autologous 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 04R047Z (abdominal aorta), 04R147Z (celiac artery), 04R247Z (gastric artery), 04R347Z (hepatic artery), 04R447Z (splenic artery), 04R547Z (superior mesenteric artery) and 24 more.

The same procedure with a different approach is coded 04RB07Z (open).

With a different device, use 04RB4JZ (synthetic substitute) and 04RB4KZ (nonautologous tissue 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.
