About 0NP0XMZ

0NP0XMZ is the ICD-10-PCS code for a removal procedure on the skull using an external approach with bone growth stimulator. In ICD-10-PCS, removal means taking out or off a device from a body part.

In plain terms, this corresponds to removal of intracranial neurostimulator lead(s), the ICD-9-CM procedure title it maps to (01.22).

For a different body part, codes include 0NPBXMZ (nasal bone) and 0NPWXMZ (facial bone).

The same procedure with a different approach is coded 0NP00MZ (open), 0NP03MZ (percutaneous) and 0NP04MZ (percutaneous endoscopic).

With a different device, use 0NP0X0Z (drainage device), 0NP0X3Z (infusion device), 0NP0X4Z (internal fixation device), 0NP0X5Z (external fixation device) and 0NP0XSZ (hearing 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 1 more.

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