About 0NU147Z

0NU147Z is the ICD-10-PCS code for a supplement procedure on the frontal bone using a percutaneous endoscopic approach with autologous 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 0NU047Z (skull), 0NU347Z (right parietal bone), 0NU447Z (left parietal bone), 0NU547Z (right temporal bone), 0NU647Z (left temporal bone), 0NU747Z (occipital bone) and 16 more.

The same procedure with a different approach is coded 0NU107Z (open) and 0NU137Z (percutaneous).

With a different device, use 0NU14JZ (synthetic substitute) and 0NU14KZ (nonautologous tissue 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.
