About 0GT20ZZ

0GT20ZZ is the ICD-10-PCS code for a resection procedure on the left adrenal gland using an open approach. In ICD-10-PCS, resection means cutting out or off, without replacement, all of a body part.

In plain terms, this corresponds to unilateral adrenalectomy, the ICD-9-CM procedure title it maps to (07.22).

For a different body part, codes include 0GT00ZZ (pituitary gland), 0GT10ZZ (pineal body), 0GT30ZZ (right adrenal gland), 0GT40ZZ (bilateral adrenal glands), 0GT60ZZ (left carotid body), 0GT70ZZ (right carotid body) and 16 more.

The same procedure with a different approach is coded 0GT24ZZ (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC), DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC), DRG 614 (Adrenal and Pituitary Procedures with CC/MCC) and DRG 615 (Adrenal and Pituitary Procedures without CC/MCC), under the surgical categories “Other Skin, Subcutaneous Tissue and Breast Procedures” and “Adrenal and Pituitary Procedures”.

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