About 0GQ00ZZ

0GQ00ZZ is the ICD-10-PCS code for a repair procedure on the pituitary gland using an open approach. In ICD-10-PCS, repair means restoring, to the extent possible, a body part to its normal anatomic structure and function.

In plain terms, this corresponds to other operations on hypophysis, the ICD-9-CM procedure title it maps to (07.79).

For a different body part, codes include 0GQ10ZZ (pineal body), 0GQ20ZZ (left adrenal gland), 0GQ30ZZ (right adrenal gland), 0GQ40ZZ (bilateral adrenal glands), 0GQ60ZZ (left carotid body), 0GQ70ZZ (right carotid body) and 16 more.

The same procedure with a different approach is coded 0GQ03ZZ (percutaneous) and 0GQ04ZZ (percutaneous endoscopic).

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.
