About 031S0JG

031S0JG is the ICD-10-PCS code for a bypass procedure on the right temporal artery using an open approach with synthetic substitute (qualifier: intracranial 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 Extracranial-intracranial (EC-IC) vascular bypass, the ICD-9-CM procedure title it maps to (39.28).

For a different body part, codes include 031G0JG (intracranial artery), 031H0JG (right common carotid artery), 031J0JG (left common carotid artery) and 031T0JG (left temporal artery).

With a different device, use 031S09G (autologous venous tissue), 031S0AG (autologous arterial tissue), 031S0KG (nonautologous tissue substitute) and 031S0ZG (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 020 (Intracranial Vascular Procedures with Principal Diagnosis Hemorrhage with MCC), DRG 021 (Intracranial Vascular Procedures with Principal Diagnosis Hemorrhage with CC), DRG 022 (Intracranial Vascular Procedures with Principal Diagnosis Hemorrhage without CC/MCC), DRG 023 (Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis with MCC or Antineoplastic Implant or Epilepsy with Neurostimulator), DRG 024 (Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis without MCC) and DRG 025 (Craniotomy and Endovascular Intracranial Procedures with MCC), under the surgical categories “Intracranial Vascular Procedures with Principal Diagnosis Hemorrhage”, “Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis”, “Craniotomy and endovascular intracranial procedures” and 2 more.

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