About 0GJ00ZZ
0GJ00ZZ is the ICD-10-PCS code for a inspection procedure on the pituitary gland using an open approach. In ICD-10-PCS, inspection means visually and/or manually exploring a body part.
In plain terms, this corresponds to exploration of pituitary fossa, the ICD-9-CM procedure title it maps to (07.71).
For a different body part, codes include 0GJ10ZZ (pineal body), 0GJ50ZZ (adrenal gland), 0GJK0ZZ (thyroid gland), 0GJR0ZZ (parathyroid gland) and 0GJS0ZZ (endocrine gland).
The same procedure with a different approach is coded 0GJ03ZZ (percutaneous) and 0GJ04ZZ (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 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.
