About 0CTT4ZZ

0CTT4ZZ is the ICD-10-PCS code for a resection procedure on the right vocal cord using a percutaneous 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 0CTM4ZZ (pharynx), 0CTR4ZZ (epiglottis), 0CTS4ZZ (larynx) and 0CTV4ZZ (left vocal cord).

The same procedure with a different approach is coded 0CTT0ZZ (open), 0CTT7ZZ (via natural or artificial opening) and 0CTT8ZZ (via natural or artificial opening endoscopic).

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.
