About 0NW03KZ

0NW03KZ is the ICD-10-PCS code for a revision procedure on the skull using a percutaneous approach with nonautologous tissue substitute. In ICD-10-PCS, revision means correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device.

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 0NWB3KZ (nasal bone) and 0NWW3KZ (facial bone).

The same procedure with a different approach is coded 0NW00KZ (open), 0NW04KZ (percutaneous endoscopic) and 0NW0XKZ (external).

With a different device, use 0NW030Z (drainage device), 0NW033Z (infusion device), 0NW034Z (internal fixation device), 0NW035Z (external fixation device), 0NW037Z (autologous tissue substitute), 0NW03JZ (synthetic 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.
