About 0GN40ZZ

0GN40ZZ is the ICD-10-PCS code for a release procedure on the bilateral adrenal glands using an open approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.

In plain terms, this corresponds to repair of adrenal gland, the ICD-9-CM procedure title it maps to (07.44).

For a different body part, codes include 0GN00ZZ (pituitary gland), 0GN10ZZ (pineal body), 0GN20ZZ (left adrenal gland), 0GN30ZZ (right adrenal gland), 0GN60ZZ (left carotid body), 0GN70ZZ (right carotid body) and 15 more.

The same procedure with a different approach is coded 0GN43ZZ (percutaneous) and 0GN44ZZ (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 614 (Adrenal and Pituitary Procedures with CC/MCC), DRG 615 (Adrenal and Pituitary Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC), DRG 909 (Other O.R. Procedures for Injuries without CC/MCC) and DRG 957 (Other O.R. Procedures for Multiple Significant Trauma with MCC), under the surgical categories “Adrenal and Pituitary Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

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