0N9140ZDrainage of Frontal Bone with Drainage Device, Percutaneous Endoscopic Approach

0N9140Z is the ICD-10-PCS code for a drainage procedure on the frontal bone using a percutaneous endoscopic approach with drainage device. 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 0N9040Z (skull), 0N9340Z (right parietal bone), 0N9440Z (left parietal bone), 0N9540Z (right temporal bone), 0N9640Z (left temporal bone), 0N9740Z (occipital bone) and 16 more.

The same procedure with a different approach is coded 0N9100Z (open) and 0N9130Z (percutaneous).

With a different device, use 0N914ZZ (no 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.
