0N910ZZDrainage of Frontal Bone, Open Approach

0N910ZZ is the ICD-10-PCS code for a drainage procedure on the frontal bone 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 incision and drainage of cranial sinus, the ICD-9-CM procedure title it maps to (01.21).

For a different body part, codes include 0N900ZZ (skull), 0N930ZZ (right parietal bone), 0N940ZZ (left parietal bone), 0N950ZZ (right temporal bone), 0N960ZZ (left temporal bone), 0N970ZZ (occipital bone) and 16 more.

The same procedure with a different approach is coded 0N913ZZ (percutaneous) and 0N914ZZ (percutaneous endoscopic).

With a different device, use 0N9100Z (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 955 (Craniotomy for Multiple Significant Trauma), under the surgical categories “Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis”, “Craniotomy and endovascular intracranial procedures” and “Craniotomy for Multiple Significant Trauma”.

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