0W910ZZDrainage of Cranial Cavity, Open Approach

0W910ZZ is the ICD-10-PCS code for a drainage procedure on the cranial cavity using an open approach. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases 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 0W900ZZ (head), 0W920ZZ (face), 0W930ZZ (oral cavity and throat), 0W940ZZ (upper jaw), 0W950ZZ (lower jaw), 0W960ZZ (neck) and 13 more.

The same procedure with a different approach is coded 0W913ZZ (percutaneous) and 0W914ZZ (percutaneous endoscopic).

With a different device, use 0W9100Z (drainage 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), 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.
