About 041L09Q
041L09Q is the ICD-10-PCS code for a bypass procedure on the left femoral artery using an open approach with autologous venous 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 (peripheral) vascular shunt or bypass, the ICD-9-CM procedure title it maps to (39.29).
For a different body part, codes include 041009Q (abdominal aorta), 041C09Q (right common iliac artery), 041D09Q (left common iliac artery), 041E09Q (right internal iliac artery), 041F09Q (left internal iliac artery), 041H09Q (right external iliac artery) and 8 more.
The same procedure with a different approach is coded 041L49Q (percutaneous endoscopic).
With a different device, use 041L0AQ (autologous arterial tissue), 041L0JQ (synthetic substitute), 041L0KQ (nonautologous tissue substitute) and 041L0ZQ (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) and DRG 254 (Other Vascular Procedures without CC/MCC), under the surgical category “Other Vascular Procedures”.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
