About 031209W
031209W is the ICD-10-PCS code for a bypass procedure on the innominate 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 03120AW (autologous arterial tissue), 03120JW (synthetic substitute), 03120KW (nonautologous tissue substitute) and 03120ZW (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), DRG 254 (Other Vascular Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Other Vascular Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.
