About 0G9400Z

0G9400Z is the ICD-10-PCS code for a drainage procedure on the bilateral adrenal glands using an open approach with drainage device. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to incision of adrenal gland, the ICD-9-CM procedure title it maps to (07.41).

For a different body part, codes include 0G9000Z (pituitary gland), 0G9100Z (pineal body), 0G9200Z (left adrenal gland), 0G9300Z (right adrenal gland), 0G9600Z (left carotid body), 0G9700Z (right carotid body) and 15 more.

The same procedure with a different approach is coded 0G9430Z (percutaneous) and 0G9440Z (percutaneous endoscopic).

With a different device, use 0G940ZZ (no device).

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.
