About 041C4AQ
041C4AQ is the ICD-10-PCS code for a bypass procedure on the right common iliac artery using a percutaneous endoscopic approach with autologous arterial tissue (qualifier: lower extremity 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 04104AQ (abdominal aorta), 041D4AQ (left common iliac artery), 041E4AQ (right internal iliac artery), 041F4AQ (left internal iliac artery), 041H4AQ (right external iliac artery), 041J4AQ (left external iliac artery) and 8 more.
The same procedure with a different approach is coded 041C0AQ (open).
With a different device, use 041C49Q (autologous venous tissue), 041C4JQ (synthetic substitute), 041C4KQ (nonautologous tissue substitute) and 041C4ZQ (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.
