About 041D491

041D491 is the ICD-10-PCS code for a bypass procedure on the left common iliac artery using a percutaneous endoscopic approach with autologous venous tissue (qualifier: celiac 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 0410491 (abdominal aorta) and 041C491 (right common iliac artery).

The same procedure with a different approach is coded 041D091 (open).

With a different device, use 041D4A1 (autologous arterial tissue), 041D4J1 (synthetic substitute), 041D4K1 (nonautologous tissue substitute) and 041D4Z1 (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.
