About 03120KY

03120KY is the ICD-10-PCS code for a bypass procedure on the innominate artery using an open approach with nonautologous tissue substitute (qualifier: upper artery). In ICD-10-PCS, bypass means altering the route of passage of the contents of a tubular body part.

For a different body part, codes include 031H0KY (right common carotid artery) and 031J0KY (left common carotid artery).

With a different device, use 031209Y (autologous venous tissue), 03120AY (autologous arterial tissue), 03120JY (synthetic substitute) and 03120ZY (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 209 (Complex Aortic Arch Procedures), 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 categories “Complex Aortic Arch Procedures” and “Other Vascular Procedures”.
