About 0NN53ZZ

0NN53ZZ is the ICD-10-PCS code for a release procedure on the right temporal bone using a percutaneous approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.

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 0NN13ZZ (frontal bone), 0NN33ZZ (right parietal bone), 0NN43ZZ (left parietal bone), 0NN63ZZ (left temporal bone), 0NN73ZZ (occipital bone), 0NNB3ZZ (nasal bone) and 15 more.

The same procedure with a different approach is coded 0NN50ZZ (open) and 0NN54ZZ (percutaneous endoscopic).

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.
