About 03LM4BZ
03LM4BZ is the ICD-10-PCS code for a occlusion procedure on the right external carotid artery using a percutaneous endoscopic approach with intraluminal device, bioactive. In ICD-10-PCS, occlusion means completely closing an orifice or the lumen of a tubular body part.
In plain terms, this corresponds to endovascular embolization or occlusion of vessel(s) of head or neck using bioactive coils, the ICD-9-CM procedure title it maps to (39.76).
For a different body part, codes include 03LG4BZ (intracranial artery), 03LH4BZ (right common carotid artery), 03LJ4BZ (left common carotid artery), 03LK4BZ (right internal carotid artery), 03LL4BZ (left internal carotid artery), 03LN4BZ (left external carotid artery) and 2 more.
The same procedure with a different approach is coded 03LM0BZ (open) and 03LM3BZ (percutaneous).
With a different device, use 03LM4CZ (extraluminal device), 03LM4DZ (intraluminal device) and 03LM4ZZ (no 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 4 more.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
