05LL4ZZOcclusion of Intracranial Vein, Percutaneous Endoscopic Approach

05LL4ZZ is the ICD-10-PCS code for a occlusion procedure on the intracranial vein using a percutaneous endoscopic approach. In ICD-10-PCS, occlusion means completely closing an orifice or the lumen of a tubular body part.

In plain terms, this corresponds to other surgical occlusion of vessels, intracranial vessels, the ICD-9-CM procedure title it maps to (38.81).

For a different body part, codes include 05L04ZZ (azygos vein), 05L14ZZ (hemiazygos vein), 05L34ZZ (right innominate vein), 05L44ZZ (left innominate vein), 05L54ZZ (right subclavian vein), 05L64ZZ (left subclavian vein) and 19 more.

The same procedure with a different approach is coded 05LL0ZZ (open) and 05LL3ZZ (percutaneous).

With a different device, use 05LL4CZ (extraluminal device) and 05LL4DZ (intraluminal 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.
