About 041K4AL

041K4AL is the ICD-10-PCS code for a bypass procedure on the right femoral artery using a percutaneous endoscopic approach with autologous arterial tissue (qualifier: popliteal 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 041L4AL (left femoral artery), 041M4AL (right popliteal artery) and 041N4AL (left popliteal artery).

The same procedure with a different approach is coded 041K0AL (open).

With a different device, use 041K49L (autologous venous tissue), 041K4JL (synthetic substitute), 041K4KL (nonautologous tissue substitute) and 041K4ZL (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 037 (Extracranial Procedures with MCC), DRG 038 (Extracranial Procedures with CC), DRG 039 (Extracranial Procedures without CC/MCC), DRG 166 (Other Respiratory System O.R. Procedures with MCC), DRG 167 (Other Respiratory System O.R. Procedures with CC) and DRG 168 (Other Respiratory System O.R. Procedures without CC/MCC), under the surgical categories “Extracranial Procedures”, “Other Respiratory System O.R. Procedures”, “Other Vascular Procedures” and 4 more.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
