About 057L4DZ
057L4DZ is the ICD-10-PCS code for a dilation procedure on the intracranial vein using a percutaneous endoscopic approach with intraluminal device. In ICD-10-PCS, dilation means expanding an orifice or the lumen of a tubular body part.
In plain terms, this corresponds to procedure on single vessel, insertion of one vascular stent, percutaneous angioplasty of intracranial vessel(s) and 1 more, the ICD-9-CM procedure titles it maps to (00.40, 00.45, 00.62 and 1 more).
For a different body part, codes include 05704DZ (azygos vein), 05714DZ (hemiazygos vein), 05734DZ (right innominate vein), 05744DZ (left innominate vein), 05754DZ (right subclavian vein), 05764DZ (left subclavian vein) and 19 more.
The same procedure with a different approach is coded 057L0DZ (open) and 057L3DZ (percutaneous).
With a different device, use 057L4ZZ (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 3 more.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
