About 04134ZR

04134ZR is the ICD-10-PCS code for a bypass procedure on the hepatic artery using a percutaneous endoscopic approach (qualifier: lower artery). In ICD-10-PCS, bypass means altering the route of passage of the contents of a tubular body part.

For a different body part, codes include 04104ZR (abdominal aorta), 04144ZR (splenic artery), 041C4ZR (right common iliac artery) and 041D4ZR (left common iliac artery).

The same procedure with a different approach is coded 04130ZR (open).

With a different device, use 041349R (autologous venous tissue), 04134AR (autologous arterial tissue), 04134JR (synthetic substitute) and 04134KR (nonautologous tissue substitute).

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), DRG 254 (Other Vascular Procedures without CC/MCC), DRG 907 (Other O.R.
