About 0GWR00Z

0GWR00Z is the ICD-10-PCS code for a revision procedure on the parathyroid gland using an open approach with drainage device. In ICD-10-PCS, revision means correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device.

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 0GW000Z (pituitary gland), 0GW100Z (pineal body), 0GW500Z (adrenal gland), 0GWK00Z (thyroid gland) and 0GWS00Z (endocrine gland).

The same procedure with a different approach is coded 0GWR30Z (percutaneous), 0GWR40Z (percutaneous endoscopic) and 0GWRX0Z (external).

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. Procedures”, “Other Skin, Subcutaneous Tissue and Breast Procedures”, “Thyroid, Parathyroid and Thyroglossal Procedures” and 2 more.

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