About 05CL4ZZ

05CL4ZZ is the ICD-10-PCS code for a extirpation procedure on the intracranial vein using a percutaneous endoscopic approach. In ICD-10-PCS, extirpation means taking or cutting out solid matter from a body part.

In plain terms, this corresponds to incision of vessel, intracranial vessels, the ICD-9-CM procedure title it maps to (38.01).

For a different body part, codes include 05C04ZZ (azygos vein), 05C14ZZ (hemiazygos vein), 05C34ZZ (right innominate vein), 05C44ZZ (left innominate vein), 05C54ZZ (right subclavian vein), 05C64ZZ (left subclavian vein) and 19 more.

The same procedure with a different approach is coded 05CL0ZZ (open) and 05CL3ZZ (percutaneous).

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.
