About 0GW040Z

0GW040Z is the ICD-10-PCS code for a revision procedure on the pituitary gland using a percutaneous endoscopic approach with drainage device. In ICD-10-PCS, revision means correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device.

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 0GW140Z (pineal body), 0GW540Z (adrenal gland), 0GWK40Z (thyroid gland), 0GWR40Z (parathyroid gland) and 0GWS40Z (endocrine gland).

The same procedure with a different approach is coded 0GW000Z (open), 0GW030Z (percutaneous) and 0GW0X0Z (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 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.
