About 0G940ZX

0G940ZX is the ICD-10-PCS code for a drainage procedure on the bilateral adrenal glands using an open approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to open biopsy of adrenal gland, the ICD-9-CM procedure title it maps to (07.12).

For a different body part, codes include 0G900ZX (pituitary gland), 0G910ZX (pineal body), 0G920ZX (left adrenal gland), 0G930ZX (right adrenal gland), 0G960ZX (left carotid body), 0G970ZX (right carotid body) and 15 more.

The same procedure with a different approach is coded 0G943ZX (percutaneous) and 0G944ZX (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 614 (Adrenal and Pituitary Procedures with CC/MCC) and DRG 615 (Adrenal and Pituitary Procedures without CC/MCC), under the surgical category “Adrenal and Pituitary Procedures”.

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