0G9100ZDrainage of Pineal Body with Drainage Device, Open Approach

0G9100Z is the ICD-10-PCS code for a drainage procedure on the pineal body using an open 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 of pineal gland, the ICD-9-CM procedure title it maps to (07.52).

For a different body part, codes include 0G9000Z (pituitary gland), 0G9200Z (left adrenal gland), 0G9300Z (right adrenal gland), 0G9400Z (bilateral adrenal glands), 0G9600Z (left carotid body), 0G9700Z (right carotid body) and 15 more.

The same procedure with a different approach is coded 0G9130Z (percutaneous) and 0G9140Z (percutaneous endoscopic).

With a different device, use 0G910ZZ (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 614 (Adrenal and Pituitary Procedures with CC/MCC), under the surgical categories “Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis”, “Craniotomy and endovascular intracranial procedures” and “Adrenal and Pituitary Procedures”.

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