About 0C5M4ZZ

0C5M4ZZ is the ICD-10-PCS code for a destruction procedure on the pharynx using a percutaneous endoscopic approach. In ICD-10-PCS, destruction means physical eradication of all or a portion of a body part by the direct use of energy, force, or a destructive agent.

In plain terms, this corresponds to other excision or destruction of lesion or tissue of pharynx, the ICD-9-CM procedure title it maps to (29.39).

For a different body part, codes include 0C5R4ZZ (epiglottis), 0C5S4ZZ (larynx), 0C5T4ZZ (right vocal cord) and 0C5V4ZZ (left vocal cord).

The same procedure with a different approach is coded 0C5M0ZZ (open), 0C5M3ZZ (percutaneous), 0C5M7ZZ (via natural or artificial opening) and 0C5M8ZZ (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 326 (Stomach, Esophageal and Duodenal Procedures with MCC), DRG 327 (Stomach, Esophageal and Duodenal Procedures with CC) and DRG 328 (Stomach, Esophageal and Duodenal Procedures without CC/MCC), under the surgical categories “Other Ear, Nose, Mouth and Throat O.R. Procedures” and “Stomach, Esophageal and Duodenal Procedures”.

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