About 0GNP3ZZ

0GNP3ZZ is the ICD-10-PCS code for a release procedure on the left inferior parathyroid gland using a percutaneous 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 other operations on parathyroid glands, the ICD-9-CM procedure title it maps to (06.99).

For a different body part, codes include 0GN03ZZ (pituitary gland), 0GN13ZZ (pineal body), 0GN23ZZ (left adrenal gland), 0GN33ZZ (right adrenal gland), 0GN43ZZ (bilateral adrenal glands), 0GN63ZZ (left carotid body) and 15 more.

The same procedure with a different approach is coded 0GNP0ZZ (open) and 0GNP4ZZ (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.
