About 03140ZK

03140ZK is the ICD-10-PCS code for a bypass procedure on the left subclavian artery using an open approach (qualifier: left extracranial 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 03120ZK (innominate artery), 03130ZK (right subclavian artery), 03150ZK (right axillary artery), 03160ZK (left axillary artery), 031H0ZK (right common carotid artery), 031J0ZK (left common carotid artery) and 4 more.

With a different device, use 031409K (autologous venous tissue), 03140AK (autologous arterial tissue), 03140JK (synthetic substitute) and 03140KK (nonautologous tissue substitute).

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”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
