About 0CWS80Z

0CWS80Z is the ICD-10-PCS code for a revision procedure on the larynx using a via natural or artificial opening 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 incision of larynx or trachea, the ICD-9-CM procedure title it maps to (31.3).

For a different body part, codes include 0CWY80Z (mouth and throat).

The same procedure with a different approach is coded 0CWS00Z (open), 0CWS30Z (percutaneous), 0CWS70Z (via natural or artificial opening) and 0CWSX0Z (external).

With a different device, use 0CWS87Z (autologous tissue substitute), 0CWS8DZ (intraluminal device), 0CWS8JZ (synthetic substitute), 0CWS8KZ (nonautologous tissue substitute) and 0CWS8YZ (other 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) and DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), under the surgical category “Other Ear, Nose, Mouth and Throat O.R. Procedures”.

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