About 0CUS77Z

0CUS77Z is the ICD-10-PCS code for a supplement procedure on the larynx using a via natural or artificial opening approach with autologous tissue substitute. In ICD-10-PCS, supplement means putting in or on biological or synthetic material that physically reinforces and/or augments the function of a portion of a body part.

In plain terms, this corresponds to other repair of larynx, the ICD-9-CM procedure title it maps to (31.69).

For a different body part, codes include 0CUM77Z (pharynx), 0CUR77Z (epiglottis), 0CUT77Z (right vocal cord) and 0CUV77Z (left vocal cord).

The same procedure with a different approach is coded 0CUS07Z (open) and 0CUS87Z (via natural or artificial opening endoscopic).

With a different device, use 0CUS7JZ (synthetic substitute) and 0CUS7KZ (nonautologous tissue substitute).

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 166 (Other Respiratory System O.R. Procedures with MCC), DRG 167 (Other Respiratory System O.R. Procedures with CC) and DRG 168 (Other Respiratory System O.R. Procedures without CC/MCC), under the surgical categories “Other Ear, Nose, Mouth and Throat O.R. Procedures”, “Other Respiratory System O.R. Procedures” and “Other O.R. Procedures for Injuries”.

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