About 0WF10ZZ

0WF10ZZ is the ICD-10-PCS code for a fragmentation procedure on the cranial cavity using an open approach. In ICD-10-PCS, fragmentation means breaking solid matter in a body part into pieces.

In plain terms, this corresponds to repair of brain, the ICD-9-CM procedure title it maps to (02.92).

For a different body part, codes include 0WF30ZZ (oral cavity and throat), 0WF90ZZ (right pleural cavity), 0WFB0ZZ (left pleural cavity), 0WFC0ZZ (mediastinum), 0WFD0ZZ (pericardial cavity), 0WFG0ZZ (peritoneal cavity) and 4 more.

The same procedure with a different approach is coded 0WF13ZZ (percutaneous), 0WF14ZZ (percutaneous endoscopic) and 0WF1XZZ (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 907 (Other O.R. Procedures for Injuries with MCC), under the surgical categories “Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis”, “Craniotomy and endovascular intracranial procedures”, “Other O.R.
