03LL3ZZOcclusion of Left Internal Carotid Artery, Percutaneous Approach

03LL3ZZ is the ICD-10-PCS code for a occlusion procedure on the left internal carotid artery using a percutaneous 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, other vessels of head and neck, the ICD-9-CM procedure title it maps to (38.82).

For a different body part, codes include 03L03ZZ (right internal mammary artery), 03L13ZZ (left internal mammary artery), 03L23ZZ (innominate artery), 03L33ZZ (right subclavian artery), 03L43ZZ (left subclavian artery), 03L53ZZ (right axillary artery) and 23 more.

The same procedure with a different approach is coded 03LL0ZZ (open) and 03LL4ZZ (percutaneous endoscopic).

With a different device, use 03LL3BZ (intraluminal device, bioactive), 03LL3CZ (extraluminal device) and 03LL3DZ (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 1 more.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
