About 0GBG4ZZ

0GBG4ZZ is the ICD-10-PCS code for a excision procedure on the left thyroid gland lobe using a percutaneous endoscopic approach. In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to excision of lesion of thyroid and other partial thyroidectomy, the ICD-9-CM procedure titles it maps to (06.31 and 06.39).

For a different body part, codes include 0GB04ZZ (pituitary gland), 0GB14ZZ (pineal body), 0GB24ZZ (left adrenal gland), 0GB34ZZ (right adrenal gland), 0GB44ZZ (bilateral adrenal glands), 0GB64ZZ (left carotid body) and 15 more.

The same procedure with a different approach is coded 0GBG0ZZ (open) and 0GBG3ZZ (percutaneous).

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.
