About 03120KW

03120KW is the ICD-10-PCS code for a bypass procedure on the innominate artery using an open approach with nonautologous tissue substitute (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 031209W (autologous venous tissue), 03120AW (autologous arterial tissue), 03120JW (synthetic 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.
