About 041U0AS

041U0AS is the ICD-10-PCS code for a bypass procedure on the left peroneal artery using an open approach with autologous arterial 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 041K0AS (right femoral artery), 041L0AS (left femoral artery), 041M0AS (right popliteal artery), 041N0AS (left popliteal artery), 041T0AS (right peroneal artery), 041V0AS (right foot artery) and 1 more.

The same procedure with a different approach is coded 041U4AS (percutaneous endoscopic).

With a different device, use 041U09S (autologous venous tissue), 041U0JS (synthetic substitute), 041U0KS (nonautologous tissue substitute) and 041U0ZS (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 was added in FY2018, effective October 1, 2017.
