About 0NQ10ZZ

0NQ10ZZ is the ICD-10-PCS code for a repair procedure on the frontal bone using an open approach. In ICD-10-PCS, repair means restoring, to the extent possible, a body part to its normal anatomic structure and function.

In plain terms, this corresponds to other cranial osteoplasty, the ICD-9-CM procedure title it maps to (02.06).

For a different body part, codes include 0NQ00ZZ (skull), 0NQ30ZZ (right parietal bone), 0NQ40ZZ (left parietal bone), 0NQ50ZZ (right temporal bone), 0NQ60ZZ (left temporal bone), 0NQ70ZZ (occipital bone) and 16 more.

The same procedure with a different approach is coded 0NQ13ZZ (percutaneous), 0NQ14ZZ (percutaneous endoscopic) and 0NQ1XZZ (external).

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 3 more.

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