About 0G9B0ZZ

0G9B0ZZ is the ICD-10-PCS code for a drainage procedure on the coccygeal glomus using an open approach. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to other operations on carotid body, carotid sinus and other vascular bodies, the ICD-9-CM procedure title it maps to (39.89).

For a different body part, codes include 0G900ZZ (pituitary gland), 0G910ZZ (pineal body), 0G920ZZ (left adrenal gland), 0G930ZZ (right adrenal gland), 0G940ZZ (bilateral adrenal glands), 0G960ZZ (left carotid body) and 15 more.

The same procedure with a different approach is coded 0G9B3ZZ (percutaneous) and 0G9B4ZZ (percutaneous endoscopic).

With a different device, use 0G9B00Z (drainage device).

It is an operating-room procedure in the MS-DRG logic for DRG 252 (Other Vascular Procedures with MCC), DRG 253 (Other Vascular Procedures with CC) and DRG 254 (Other Vascular Procedures without CC/MCC), under the surgical category “Other Vascular Procedures”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
