About 041309R

041309R is the ICD-10-PCS code for a bypass procedure on the hepatic artery using an open approach with autologous venous tissue (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 041009R (abdominal aorta), 041409R (splenic artery), 041C09R (right common iliac artery) and 041D09R (left common iliac artery).

The same procedure with a different approach is coded 041349R (percutaneous endoscopic).

With a different device, use 04130AR (autologous arterial tissue), 04130JR (synthetic substitute), 04130KR (nonautologous tissue substitute) and 04130ZR (no device).

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.

Procedures for Injuries without CC/MCC), under the surgical categories “Other Vascular Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.
