About 0GWS4YZ

0GWS4YZ is the ICD-10-PCS code for a revision procedure on the endocrine gland using a percutaneous endoscopic approach with other 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 0GWS0YZ (open) and 0GWS3YZ (percutaneous).

With a different device, use 0GWS40Z (drainage device), 0GWS42Z (monitoring device) and 0GWS43Z (infusion device).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It was added in FY2018, effective October 1, 2017.
