About 041M49S

041M49S is the ICD-10-PCS code for a bypass procedure on the right popliteal artery using a percutaneous endoscopic approach with autologous venous tissue (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 041K49S (right femoral artery), 041L49S (left femoral artery), 041N49S (left popliteal artery), 041T49S (right peroneal artery), 041U49S (left peroneal artery), 041V49S (right foot artery) and 1 more.

The same procedure with a different approach is coded 041M09S (open).

With a different device, use 041M4AS (autologous arterial tissue), 041M4JS (synthetic substitute), 041M4KS (nonautologous tissue substitute) and 041M4ZS (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.
