About 0CCM0ZZ

0CCM0ZZ is the ICD-10-PCS code for a extirpation procedure on the pharynx using an open approach. In ICD-10-PCS, extirpation means taking or cutting out solid matter from a body part.

In plain terms, this corresponds to Pharyngotomy, the ICD-9-CM procedure title it maps to (29.0).

For a different body part, codes include 0CC00ZZ (upper lip), 0CC10ZZ (lower lip), 0CC20ZZ (hard palate), 0CC30ZZ (soft palate), 0CC40ZZ (buccal mucosa), 0CC50ZZ (upper gingiva) and 18 more.

The same procedure with a different approach is coded 0CCM3ZZ (percutaneous), 0CCM4ZZ (percutaneous endoscopic), 0CCM7ZZ (via natural or artificial opening) and 0CCM8ZZ (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 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Other Ear, Nose, Mouth and Throat O.R. Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

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