About 0G800ZZ
0G800ZZ is the ICD-10-PCS code for a division procedure on the pituitary gland using an open approach. In ICD-10-PCS, division means cutting into a body part, without draining fluids and/or gases from the body part, in order to separate or transect a body part.
In plain terms, this corresponds to partial excision of pituitary gland, transfrontal approach, the ICD-9-CM procedure title it maps to (07.61).
For a different body part, codes include 0G8J0ZZ (thyroid gland isthmus).
The same procedure with a different approach is coded 0G803ZZ (percutaneous) and 0G804ZZ (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.
