0NH03MZInsertion of Bone Growth Stimulator into Skull, Percutaneous Approach

0NH03MZ is the ICD-10-PCS code for a insertion procedure on the skull using a percutaneous approach with bone growth stimulator. 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 other craniotomy, the ICD-9-CM procedure title it maps to (01.24).

For a different body part, codes include 0NHB3MZ (nasal bone) and 0NHW3MZ (facial bone).

The same procedure with a different approach is coded 0NH00MZ (open) and 0NH04MZ (percutaneous endoscopic).

With a different device, use 0NH033Z (infusion device), 0NH034Z (internal fixation device) and 0NH035Z (external fixation device).

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) and DRG 027 (Craniotomy and Endovascular Intracranial Procedures without CC/MCC), under the surgical categories “Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis” and “Craniotomy and endovascular intracranial procedures”.

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