About 0NP0XSZ
0NP0XSZ is the ICD-10-PCS code for a removal procedure on the skull using an external approach with hearing device. In ICD-10-PCS, removal means taking out or off a device from a body part.
In plain terms, this corresponds to other craniotomy, the ICD-9-CM procedure title it maps to (01.24).
The same procedure with a different approach is coded 0NP00SZ (open), 0NP03SZ (percutaneous) and 0NP04SZ (percutaneous endoscopic).
With a different device, use 0NP0X0Z (drainage device), 0NP0X3Z (infusion device), 0NP0X4Z (internal fixation device), 0NP0X5Z (external fixation device) and 0NP0XMZ (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) 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.
