About 031L09J

031L09J is the ICD-10-PCS code for a bypass procedure on the left internal carotid artery using an open approach with autologous venous tissue (qualifier: right 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 Aorta-subclavian-carotid bypass, the ICD-9-CM procedure title it maps to (39.22).

For a different body part, codes include 031209J (innominate artery), 031309J (right subclavian artery), 031409J (left subclavian artery), 031509J (right axillary artery), 031609J (left axillary artery), 031H09J (right common carotid artery) and 4 more.

With a different device, use 031L0AJ (autologous arterial tissue), 031L0JJ (synthetic substitute), 031L0KJ (nonautologous tissue substitute) and 031L0ZJ (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 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 “Extracranial Procedures”, “Other Vascular Procedures”, “Other O.R. Procedures for Injuries” and 1 more.

It was added in FY2018, effective October 1, 2017.
