About 055L0ZZ
055L0ZZ is the ICD-10-PCS code for a destruction procedure on the intracranial vein using an open approach. In ICD-10-PCS, destruction means physical eradication of all or a portion of a body part by the direct use of energy, force, or a destructive agent.
In plain terms, this corresponds to other excision of vessels, intracranial vessels, the ICD-9-CM procedure title it maps to (38.61).
For a different body part, codes include 05500ZZ (azygos vein), 05510ZZ (hemiazygos vein), 05530ZZ (right innominate vein), 05540ZZ (left innominate vein), 05550ZZ (right subclavian vein), 05560ZZ (left subclavian vein) and 19 more.
The same procedure with a different approach is coded 055L3ZZ (percutaneous) and 055L4ZZ (percutaneous endoscopic).
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.
