About 0G9R00Z

0G9R00Z is the ICD-10-PCS code for a drainage procedure on the parathyroid gland using an open approach with drainage device. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to other incision of thyroid field, the ICD-9-CM procedure title it maps to (06.09).

For a different body part, codes include 0G9000Z (pituitary gland), 0G9100Z (pineal body), 0G9200Z (left adrenal gland), 0G9300Z (right adrenal gland), 0G9400Z (bilateral adrenal glands), 0G9600Z (left carotid body) and 15 more.

The same procedure with a different approach is coded 0G9R30Z (percutaneous) and 0G9R40Z (percutaneous endoscopic).

With a different device, use 0G9R0ZZ (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 143 (Other Ear, Nose, Mouth and Throat O.R. Procedures with MCC), DRG 144 (Other Ear, Nose, Mouth and Throat O.R. Procedures with CC), DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), DRG 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC) and DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC), under the surgical categories “Other Ear, Nose, Mouth and Throat O.R.
