0WH10YZInsertion of Other Device into Cranial Cavity, Open Approach

0WH10YZ is the ICD-10-PCS code for a insertion procedure on the cranial cavity using an open approach with other 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 other craniotomy, the ICD-9-CM procedure title it maps to (01.24).

For a different body part, codes include 0WH00YZ (head), 0WH20YZ (face), 0WH30YZ (oral cavity and throat), 0WH40YZ (upper jaw), 0WH50YZ (lower jaw), 0WH60YZ (neck) and 16 more.

The same procedure with a different approach is coded 0WH13YZ (percutaneous) and 0WH14YZ (percutaneous endoscopic).

With a different device, use 0WH101Z (radioactive element) and 0WH103Z (infusion 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.
