About 0NP044Z

0NP044Z is the ICD-10-PCS code for a removal procedure on the skull using a percutaneous endoscopic approach with internal fixation device. In ICD-10-PCS, removal means taking out or off a device from a body part.

In plain terms, this corresponds to other craniotomy, the ICD-9-CM procedure title it maps to (01.24).

For a different body part, codes include 0NPB44Z (nasal bone) and 0NPW44Z (facial bone).

The same procedure with a different approach is coded 0NP004Z (open), 0NP034Z (percutaneous) and 0NP0X4Z (external).

With a different device, use 0NP040Z (drainage device), 0NP043Z (infusion device), 0NP045Z (external fixation device), 0NP047Z (autologous tissue substitute), 0NP04JZ (synthetic substitute), 0NP04KZ (nonautologous tissue substitute) and 2 more.

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) and DRG 027 (Craniotomy and Endovascular Intracranial Procedures without CC/MCC), under the surgical categories “Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis” and “Craniotomy and endovascular intracranial procedures”.

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