About 0GBM0ZZ

0GBM0ZZ is the ICD-10-PCS code for a excision procedure on the left superior parathyroid gland using an open 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 other parathyroidectomy, the ICD-9-CM procedure title it maps to (06.89).

For a different body part, codes include 0GB00ZZ (pituitary gland), 0GB10ZZ (pineal body), 0GB20ZZ (left adrenal gland), 0GB30ZZ (right adrenal gland), 0GB40ZZ (bilateral adrenal glands), 0GB60ZZ (left carotid body) and 15 more.

The same procedure with a different approach is coded 0GBM3ZZ (percutaneous) and 0GBM4ZZ (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), DRG 627 (Thyroid, Parathyroid and Thyroglossal Procedures without CC/MCC), DRG 673 (Other Kidney and Urinary Tract Procedures with MCC), DRG 674 (Other Kidney and Urinary Tract Procedures with CC) and DRG 675 (Other Kidney and Urinary Tract Procedures without CC/MCC), under the surgical categories “Thyroid, Parathyroid and Thyroglossal Procedures” and “Other Kidney and Urinary Tract Procedures”.

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