About 0CWY87Z

0CWY87Z is the ICD-10-PCS code for a revision procedure on the mouth and throat using a via natural or artificial opening endoscopic 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 Pharyngotomy, the ICD-9-CM procedure title it maps to (29.0).

For a different body part, codes include 0CWS87Z (larynx).

The same procedure with a different approach is coded 0CWY07Z (open), 0CWY37Z (percutaneous), 0CWY77Z (via natural or artificial opening) and 0CWYX7Z (external).

With a different device, use 0CWY80Z (drainage device), 0CWY81Z (radioactive element), 0CWY8DZ (intraluminal device), 0CWY8JZ (synthetic substitute), 0CWY8KZ (nonautologous tissue substitute) and 0CWY8YZ (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), DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Other Ear, Nose, Mouth and Throat O.R. Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

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