About 0GTG0ZZ

0GTG0ZZ is the ICD-10-PCS code for a resection procedure on the left thyroid gland lobe 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 thyroid lobectomy, the ICD-9-CM procedure title it maps to (06.2).

For a different body part, codes include 0GT00ZZ (pituitary gland), 0GT10ZZ (pineal body), 0GT20ZZ (left adrenal gland), 0GT30ZZ (right adrenal gland), 0GT40ZZ (bilateral adrenal glands), 0GT60ZZ (left carotid body) and 16 more.

The same procedure with a different approach is coded 0GTG4ZZ (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 625 (Thyroid, Parathyroid and Thyroglossal Procedures with MCC), DRG 626 (Thyroid, Parathyroid and Thyroglossal Procedures with CC) and DRG 627 (Thyroid, Parathyroid and Thyroglossal Procedures without CC/MCC), under the surgical category “Thyroid, Parathyroid and Thyroglossal Procedures”.

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