About 0CWY07Z

0CWY07Z is the ICD-10-PCS code for a revision procedure on the mouth and throat using an open approach with autologous tissue substitute. 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 dental operations, the ICD-9-CM procedure title it maps to (24.99).

For a different body part, codes include 0CWS07Z (larynx).

The same procedure with a different approach is coded 0CWY37Z (percutaneous), 0CWY77Z (via natural or artificial opening), 0CWY87Z (via natural or artificial opening endoscopic) and 0CWYX7Z (external).

With a different device, use 0CWY00Z (drainage device), 0CWY01Z (radioactive element), 0CWY0DZ (intraluminal device), 0CWY0JZ (synthetic substitute), 0CWY0KZ (nonautologous tissue substitute) and 0CWY0YZ (other device).

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

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