About 0G9P4ZX

0G9P4ZX is the ICD-10-PCS code for a drainage procedure on the left inferior parathyroid gland using a percutaneous endoscopic approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to biopsy of parathyroid gland, the ICD-9-CM procedure title it maps to (06.13).

For a different body part, codes include 0G904ZX (pituitary gland), 0G914ZX (pineal body), 0G924ZX (left adrenal gland), 0G934ZX (right adrenal gland), 0G944ZX (bilateral adrenal glands), 0G964ZX (left carotid body) and 15 more.

The same procedure with a different approach is coded 0G9P0ZX (open) and 0G9P3ZX (percutaneous).

It is an operating-room procedure in the MS-DRG logic for DRG 515 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with MCC), DRG 516 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with CC), DRG 517 (Other Musculoskeletal System and Connective Tissue O.R. Procedures without CC/MCC), 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 categories “Other Musculoskeletal System and Connective Tissue O.R. Procedures” and “Thyroid, Parathyroid and Thyroglossal Procedures”.

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