About 0CWS3YZ

0CWS3YZ is the ICD-10-PCS code for a revision procedure on the larynx using a percutaneous 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 incision of larynx or trachea, the ICD-9-CM procedure title it maps to (31.3).

For a different body part, codes include 0CWA3YZ (salivary gland) and 0CWY3YZ (mouth and throat).

The same procedure with a different approach is coded 0CWS0YZ (open), 0CWS7YZ (via natural or artificial opening) and 0CWS8YZ (via natural or artificial opening endoscopic).

With a different device, use 0CWS30Z (drainage device), 0CWS37Z (autologous tissue substitute), 0CWS3DZ (intraluminal device), 0CWS3JZ (synthetic substitute) and 0CWS3KZ (nonautologous tissue substitute).

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.
