About 0G504ZZ

0G504ZZ is the ICD-10-PCS code for a destruction procedure on the pituitary gland using a percutaneous endoscopic approach. In ICD-10-PCS, destruction means physical eradication of all or a portion of a body part by the direct use of energy, force, or a destructive agent.

In plain terms, this corresponds to partial excision of pituitary gland, unspecified approach, the ICD-9-CM procedure title it maps to (07.63).

For a different body part, codes include 0G514ZZ (pineal body), 0G524ZZ (left adrenal gland), 0G534ZZ (right adrenal gland), 0G544ZZ (bilateral adrenal glands), 0G564ZZ (left carotid body), 0G574ZZ (right carotid body) and 15 more.

The same procedure with a different approach is coded 0G500ZZ (open) and 0G503ZZ (percutaneous).

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.
