About 041C0A9

041C0A9 is the ICD-10-PCS code for a bypass procedure on the right common iliac artery using an open approach with autologous arterial tissue (qualifier: right 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 04100A9 (abdominal aorta), 041D0A9 (left common iliac artery), 041E0A9 (right internal iliac artery), 041F0A9 (left internal iliac artery), 041H0A9 (right external iliac artery) and 041J0A9 (left external iliac artery).

The same procedure with a different approach is coded 041C4A9 (percutaneous endoscopic).

With a different device, use 041C099 (autologous venous tissue), 041C0J9 (synthetic substitute), 041C0K9 (nonautologous tissue substitute) and 041C0Z9 (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.
