About 00BC3ZX

00BC3ZX is the ICD-10-PCS code for a excision procedure on the cerebellum using a percutaneous approach (qualifier: diagnostic). In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to closed [percutaneous] [needle] biopsy of brain, the ICD-9-CM procedure title it maps to (01.13).

For a different body part, codes include 00B03ZX (brain), 00B13ZX (cerebral meninges), 00B23ZX (dura mater), 00B63ZX (cerebral ventricle), 00B73ZX (cerebral hemisphere), 00B83ZX (basal ganglia) and 20 more.

The same procedure with a different approach is coded 00BC0ZX (open) and 00BC4ZX (percutaneous endoscopic).

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 1 more.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
