About 00164KB

00164KB is the ICD-10-PCS code for a bypass procedure on the cerebral ventricle using a percutaneous endoscopic approach with nonautologous tissue substitute (qualifier: cerebral cisterns). In ICD-10-PCS, bypass means altering the route of passage of the contents of a tubular body part.

In plain terms, this corresponds to intracranial ventricular shunt or anastomosis, the ICD-9-CM procedure title it maps to (02.22).

The same procedure with a different approach is coded 00160KB (open) and 00163KB (percutaneous).

With a different device, use 001647B (autologous tissue substitute), 00164JB (synthetic substitute) and 00164ZB (no device).

It is an operating-room procedure in the MS-DRG logic for 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), DRG 025 (Craniotomy and Endovascular Intracranial Procedures with MCC), DRG 026 (Craniotomy and Endovascular Intracranial Procedures with CC), DRG 027 (Craniotomy and Endovascular Intracranial Procedures without CC/MCC) and DRG 820 (Lymphoma and Leukemia with Major O.R. Procedures with MCC), under the surgical categories “Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis”, “Craniotomy and endovascular intracranial procedures”, “Lymphoma and Leukemia with Major O.R. Procedures” and 3 more.

It was added in FY2018, effective October 1, 2017.
