About 0GWS40Z

0GWS40Z is the ICD-10-PCS code for a revision procedure on the endocrine gland using a percutaneous endoscopic 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 operations on carotid body, carotid sinus and other vascular bodies, the ICD-9-CM procedure title it maps to (39.89).

For a different body part, codes include 0GW040Z (pituitary gland), 0GW140Z (pineal body), 0GW540Z (adrenal gland), 0GWK40Z (thyroid gland) and 0GWR40Z (parathyroid gland).

The same procedure with a different approach is coded 0GWS00Z (open), 0GWS30Z (percutaneous) and 0GWSX0Z (external).

With a different device, use 0GWS42Z (monitoring device), 0GWS43Z (infusion device) and 0GWS4YZ (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.
