About 03120K2

03120K2 is the ICD-10-PCS code for a bypass procedure on the innominate artery using an open approach with nonautologous tissue substitute (qualifier: bilateral upper arm artery). 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 03130K2 (right subclavian artery), 03140K2 (left subclavian artery), 03150K2 (right axillary artery) and 03160K2 (left axillary artery).

With a different device, use 0312092 (autologous venous tissue), 03120A2 (autologous arterial tissue), 03120J2 (synthetic substitute) and 03120Z2 (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 has been valid since ICD-10-PCS took effect on October 1, 2015.
