About 041F4AB

041F4AB is the ICD-10-PCS code for a bypass procedure on the left internal iliac artery using a percutaneous endoscopic approach with autologous arterial tissue (qualifier: left internal iliac artery). In ICD-10-PCS, bypass means altering the route of passage of the contents of a tubular body part.

In plain terms, this corresponds to other intra-abdominal vascular shunt or bypass, the ICD-9-CM procedure title it maps to (39.26).

For a different body part, codes include 04104AB (abdominal aorta), 041C4AB (right common iliac artery), 041D4AB (left common iliac artery), 041E4AB (right internal iliac artery), 041H4AB (right external iliac artery) and 041J4AB (left external iliac artery).

The same procedure with a different approach is coded 041F0AB (open).

With a different device, use 041F49B (autologous venous tissue), 041F4JB (synthetic substitute), 041F4KB (nonautologous tissue substitute) and 041F4ZB (no device).

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) and DRG 272 (Other Major Cardiovascular Procedures without CC/MCC), under the surgical category “Other Major Cardiovascular Procedures”.

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