About 0NR337Z
0NR337Z is the ICD-10-PCS code for a replacement procedure on the right parietal bone using a percutaneous approach with autologous tissue substitute. In ICD-10-PCS, replacement means putting in or on biological or synthetic material that physically takes the place and/or function of all or 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 0NR037Z (skull), 0NR137Z (frontal bone), 0NR437Z (left parietal bone), 0NR537Z (right temporal bone), 0NR637Z (left temporal bone), 0NR737Z (occipital bone) and 16 more.
The same procedure with a different approach is coded 0NR307Z (open) and 0NR347Z (percutaneous endoscopic).
With a different device, use 0NR33JZ (synthetic substitute) and 0NR33KZ (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.
