About 03CL3ZZ

03CL3ZZ is the ICD-10-PCS code for a extirpation procedure on the left internal carotid artery using a percutaneous 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, percutaneous angioplasty of extracranial vessel(s), percutaneous atherectomy of extracranial vessel(s) and 1 more, the ICD-9-CM procedure titles it maps to (00.40, 00.61, 17.53 and 1 more).

For a different body part, codes include 03C03ZZ (right internal mammary artery), 03C13ZZ (left internal mammary artery), 03C23ZZ (innominate artery), 03C33ZZ (right subclavian artery), 03C43ZZ (left subclavian artery), 03C53ZZ (right axillary artery) and 23 more.

The same procedure with a different approach is coded 03CL0ZZ (open) and 03CL4ZZ (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.
