About 03CG0ZZ
03CG0ZZ is the ICD-10-PCS code for a extirpation procedure on the intracranial artery using an open approach. In ICD-10-PCS, extirpation means taking or cutting out solid matter from a body part.
In plain terms, this corresponds to procedure on single vessel, incision of vessel, intracranial vessels and Endarterectomy, intracranial vessels, the ICD-9-CM procedure titles it maps to (00.40, 38.01 and 38.11).
For a different body part, codes include 03C00ZZ (right internal mammary artery), 03C10ZZ (left internal mammary artery), 03C20ZZ (innominate artery), 03C30ZZ (right subclavian artery), 03C40ZZ (left subclavian artery), 03C50ZZ (right axillary artery) and 23 more.
The same procedure with a different approach is coded 03CG3ZZ (percutaneous) and 03CG4ZZ (percutaneous endoscopic).
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.
