About 041L4AP

041L4AP is the ICD-10-PCS code for a bypass procedure on the left femoral artery using a percutaneous endoscopic approach with autologous arterial tissue (qualifier: foot 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 041E4AP (right internal iliac artery), 041F4AP (left internal iliac artery), 041H4AP (right external iliac artery), 041J4AP (left external iliac artery), 041K4AP (right femoral artery), 041M4AP (right popliteal artery) and 5 more.

The same procedure with a different approach is coded 041L0AP (open).

With a different device, use 041L49P (autologous venous tissue), 041L4JP (synthetic substitute), 041L4KP (nonautologous tissue substitute) and 041L4ZP (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.
