0G9000ZDrainage of Pituitary Gland with Drainage Device, Open Approach

0G9000Z is the ICD-10-PCS code for a drainage procedure on the pituitary gland 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 pituitary gland, the ICD-9-CM procedure title it maps to (07.72).

For a different body part, codes include 0G9100Z (pineal body), 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 0G9030Z (percutaneous) and 0G9040Z (percutaneous endoscopic).

With a different device, use 0G900ZZ (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 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), under the surgical categories “Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis”, “Craniotomy and endovascular intracranial procedures”, “Other Skin, Subcutaneous Tissue and Breast Procedures” and 1 more.

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