03LG0ZZOcclusion of Intracranial Artery, Open Approach

03LG0ZZ is the ICD-10-PCS code for a occlusion procedure on the intracranial artery using an open 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 ligation of meningeal vessel and other surgical occlusion of vessels, intracranial vessels, the ICD-9-CM procedure titles it maps to (02.13 and 38.81).

For a different body part, codes include 03L00ZZ (right internal mammary artery), 03L10ZZ (left internal mammary artery), 03L20ZZ (innominate artery), 03L30ZZ (right subclavian artery), 03L40ZZ (left subclavian artery), 03L50ZZ (right axillary artery) and 23 more.

The same procedure with a different approach is coded 03LG3ZZ (percutaneous) and 03LG4ZZ (percutaneous endoscopic).

With a different device, use 03LG0BZ (intraluminal device, bioactive), 03LG0CZ (extraluminal device) and 03LG0DZ (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.
