About 0C9T8ZZ

0C9T8ZZ is the ICD-10-PCS code for a drainage procedure on the right vocal cord using a via natural or artificial opening endoscopic approach. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

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 0C9M8ZZ (pharynx), 0C9R8ZZ (epiglottis), 0C9S8ZZ (larynx) and 0C9V8ZZ (left vocal cord).

The same procedure with a different approach is coded 0C9T0ZZ (open), 0C9T3ZZ (percutaneous), 0C9T4ZZ (percutaneous endoscopic) and 0C9T7ZZ (via natural or artificial opening).

With a different device, use 0C9T80Z (drainage 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.
