About 0NU33KZ

0NU33KZ is the ICD-10-PCS code for a supplement procedure on the right parietal bone using a percutaneous approach with nonautologous tissue substitute. In ICD-10-PCS, supplement means putting in or on biological or synthetic material that physically reinforces and/or augments the function of a portion of a body part.

In plain terms, this corresponds to bone graft to skull, the ICD-9-CM procedure title it maps to (02.04).

For a different body part, codes include 0NU03KZ (skull), 0NU13KZ (frontal bone), 0NU43KZ (left parietal bone), 0NU53KZ (right temporal bone), 0NU63KZ (left temporal bone), 0NU73KZ (occipital bone) and 16 more.

The same procedure with a different approach is coded 0NU30KZ (open) and 0NU34KZ (percutaneous endoscopic).

With a different device, use 0NU337Z (autologous tissue substitute) and 0NU33JZ (synthetic substitute).

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 143 (Other Ear, Nose, Mouth and Throat 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”, “Other Ear, Nose, Mouth and Throat O.R. Procedures” and 1 more.

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