About 0GSN0ZZ

0GSN0ZZ is the ICD-10-PCS code for a reposition procedure on the right inferior parathyroid gland using an open approach. In ICD-10-PCS, reposition means moving to its normal location, or other suitable location, all or a portion of a body part.

In plain terms, this corresponds to parathyroid tissue reimplantation, the ICD-9-CM procedure title it maps to (06.95).

For a different body part, codes include 0GS20ZZ (left adrenal gland), 0GS30ZZ (right adrenal gland), 0GSG0ZZ (left thyroid gland lobe), 0GSH0ZZ (right thyroid gland lobe), 0GSL0ZZ (right superior parathyroid gland), 0GSM0ZZ (left superior parathyroid gland) and 3 more.

The same procedure with a different approach is coded 0GSN4ZZ (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.
