About 0CNT3ZZ

0CNT3ZZ is the ICD-10-PCS code for a release procedure on the right vocal cord using a percutaneous approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.

In plain terms, this corresponds to lysis of adhesions of trachea or larynx, the ICD-9-CM procedure title it maps to (31.92).

For a different body part, codes include 0CN03ZZ (upper lip), 0CN13ZZ (lower lip), 0CN23ZZ (hard palate), 0CN33ZZ (soft palate), 0CN43ZZ (buccal mucosa), 0CN53ZZ (upper gingiva) and 18 more.

The same procedure with a different approach is coded 0CNT0ZZ (open), 0CNT4ZZ (percutaneous endoscopic), 0CNT7ZZ (via natural or artificial opening) and 0CNT8ZZ (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.
