About 031409W

031409W is the ICD-10-PCS code for a bypass procedure on the left subclavian artery using an open 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.

With a different device, use 03140AW (autologous arterial tissue), 03140JW (synthetic substitute), 03140KW (nonautologous tissue substitute) and 03140ZW (no device).
