About 031J0AY

031J0AY is the ICD-10-PCS code for a bypass procedure on the left common carotid artery using an open approach with autologous arterial tissue (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 03120AY (innominate artery) and 031H0AY (right common carotid artery).

With a different device, use 031J09Y (autologous venous tissue), 031J0JY (synthetic substitute), 031J0KY (nonautologous tissue substitute) and 031J0ZY (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 037 (Extracranial Procedures with MCC), DRG 038 (Extracranial Procedures with CC), DRG 039 (Extracranial Procedures without CC/MCC), DRG 166 (Other Respiratory System O.R.
