About 0NH034Z

0NH034Z is the ICD-10-PCS code for a insertion procedure on the skull using a percutaneous approach with internal fixation device. In ICD-10-PCS, insertion means putting in a nonbiological appliance that monitors, assists, performs, or prevents a physiological function but does not physically take the place of a body part.

In plain terms, this corresponds to insertion or replacement of skull tongs or halo traction device, the ICD-9-CM procedure title it maps to (02.94).

For a different body part, codes include 0NH134Z (frontal bone), 0NH334Z (right parietal bone), 0NH434Z (left parietal bone), 0NH534Z (right temporal bone), 0NH634Z (left temporal bone), 0NH734Z (occipital bone) and 16 more.

The same procedure with a different approach is coded 0NH004Z (open) and 0NH044Z (percutaneous endoscopic).

With a different device, use 0NH033Z (infusion device), 0NH035Z (external fixation device) and 0NH03MZ (bone growth stimulator).

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 515 (Other Musculoskeletal System and Connective Tissue 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 Musculoskeletal System and Connective Tissue O.R. Procedures” and 2 more.

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