About 057L3ZZ

057L3ZZ is the ICD-10-PCS code for a dilation procedure on the intracranial vein using a percutaneous approach. 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 and angioplasty of other non-coronary vessel(s), the ICD-9-CM procedure titles it maps to (00.40 and 39.50).

For a different body part, codes include 05703ZZ (azygos vein), 05713ZZ (hemiazygos vein), 05733ZZ (right innominate vein), 05743ZZ (left innominate vein), 05753ZZ (right subclavian vein), 05763ZZ (left subclavian vein) and 19 more.

The same procedure with a different approach is coded 057L0ZZ (open) and 057L4ZZ (percutaneous endoscopic).

With a different device, use 057L3DZ (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.
