About 031H0KG

031H0KG is the ICD-10-PCS code for a bypass procedure on the right common carotid artery using an open approach with nonautologous tissue 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 031G0KG (intracranial artery), 031J0KG (left common carotid artery), 031S0KG (right temporal artery) and 031T0KG (left temporal artery).

With a different device, use 031H09G (autologous venous tissue), 031H0AG (autologous arterial tissue), 031H0JG (synthetic substitute) and 031H0ZG (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.
