About 041L4JS
041L4JS is the ICD-10-PCS code for a bypass procedure on the left femoral artery using a percutaneous endoscopic approach with synthetic substitute (qualifier: lower extremity vein). 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 041K4JS (right femoral artery), 041M4JS (right popliteal artery), 041N4JS (left popliteal artery), 041P4JS (right anterior tibial artery), 041Q4JS (left anterior tibial artery), 041R4JS (right posterior tibial artery) and 5 more.
The same procedure with a different approach is coded 041L0JS (open) and 041L3JS (percutaneous).
With a different device, use 041L49S (autologous venous tissue), 041L4AS (autologous arterial tissue), 041L4KS (nonautologous tissue substitute) and 041L4ZS (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.
