About 0CTT8ZZ

0CTT8ZZ is the ICD-10-PCS code for a resection procedure on the right vocal cord using a via natural or artificial opening endoscopic approach. In ICD-10-PCS, resection means cutting out or off, without replacement, all of a body part.

In plain terms, this corresponds to vocal cordectomy, the ICD-9-CM procedure title it maps to (30.22).

For a different body part, codes include 0CTM8ZZ (pharynx), 0CTR8ZZ (epiglottis), 0CTS8ZZ (larynx) and 0CTV8ZZ (left vocal cord).

The same procedure with a different approach is coded 0CTT0ZZ (open), 0CTT4ZZ (percutaneous endoscopic) and 0CTT7ZZ (via natural or artificial opening).

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”, “Other O.R. Procedures for Injuries” and 1 more.

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