About 0GWS02Z

0GWS02Z is the ICD-10-PCS code for a revision procedure on the endocrine gland using an open approach with monitoring 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 operations on carotid body, carotid sinus and other vascular bodies, the ICD-9-CM procedure title it maps to (39.89).

The same procedure with a different approach is coded 0GWS32Z (percutaneous), 0GWS42Z (percutaneous endoscopic) and 0GWSX2Z (external).

With a different device, use 0GWS00Z (drainage device), 0GWS03Z (infusion device) and 0GWS0YZ (other device).

It is an operating-room procedure in the MS-DRG logic for DRG 252 (Other Vascular Procedures with MCC), DRG 253 (Other Vascular Procedures with CC) and DRG 254 (Other Vascular Procedures without CC/MCC), under the surgical category “Other Vascular Procedures”.

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