About 0WC10ZZ

0WC10ZZ is the ICD-10-PCS code for a extirpation procedure on the cranial cavity using an open approach. In ICD-10-PCS, extirpation means taking or cutting out solid matter from 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 0WC30ZZ (oral cavity and throat), 0WC40ZZ (upper jaw), 0WC50ZZ (lower jaw), 0WC90ZZ (right pleural cavity), 0WCB0ZZ (left pleural cavity), 0WCC0ZZ (mediastinum) and 7 more.

The same procedure with a different approach is coded 0WC13ZZ (percutaneous), 0WC14ZZ (percutaneous endoscopic) and 0WC1XZZ (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 140 (Major Head and Neck Procedures with MCC), under the surgical categories “Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis”, “Craniotomy and endovascular intracranial procedures”, “Major Head and Neck Procedures” and 4 more.

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