About 03120ZC
03120ZC is the ICD-10-PCS code for a bypass procedure on the innominate artery using an open approach (qualifier: bilateral lower leg 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 03130ZC (right subclavian artery), 03140ZC (left subclavian artery), 03150ZC (right axillary artery) and 03160ZC (left axillary artery).
With a different device, use 031209C (autologous venous tissue), 03120AC (autologous arterial tissue), 03120JC (synthetic substitute) and 03120KC (nonautologous tissue substitute).
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.
