About 0GMP4ZZ

0GMP4ZZ is the ICD-10-PCS code for a reattachment procedure on the left inferior parathyroid gland using a percutaneous endoscopic approach. In ICD-10-PCS, reattachment means putting back in or on all or a portion of a separated body part to its normal location or other suitable location.

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 0GM24ZZ (left adrenal gland), 0GM34ZZ (right adrenal gland), 0GMG4ZZ (left thyroid gland lobe), 0GMH4ZZ (right thyroid gland lobe), 0GML4ZZ (right superior parathyroid gland), 0GMM4ZZ (left superior parathyroid gland) and 3 more.

The same procedure with a different approach is coded 0GMP0ZZ (open).

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.
