About 0CTR0ZZ

0CTR0ZZ is the ICD-10-PCS code for a resection procedure on the epiglottis using an open approach. In ICD-10-PCS, resection means cutting out or off, without replacement, all of a body part.

In plain terms, this corresponds to Epiglottidectomy, the ICD-9-CM procedure title it maps to (30.21).

For a different body part, codes include 0CT00ZZ (upper lip), 0CT10ZZ (lower lip), 0CT20ZZ (hard palate), 0CT30ZZ (soft palate), 0CT70ZZ (tongue), 0CT80ZZ (right parotid gland) and 15 more.

The same procedure with a different approach is coded 0CTR4ZZ (percutaneous endoscopic), 0CTR7ZZ (via natural or artificial opening) and 0CTR8ZZ (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.
