About 0CBM3ZZ

0CBM3ZZ is the ICD-10-PCS code for a excision procedure on the pharynx using a percutaneous approach. In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to Pharyngectomy (partial) and other excision or destruction of lesion or tissue of pharynx, the ICD-9-CM procedure titles it maps to (29.33 and 29.39).

For a different body part, codes include 0CB03ZZ (upper lip), 0CB13ZZ (lower lip), 0CB23ZZ (hard palate), 0CB33ZZ (soft palate), 0CB43ZZ (buccal mucosa), 0CB53ZZ (upper gingiva) and 18 more.

The same procedure with a different approach is coded 0CBM0ZZ (open), 0CBM4ZZ (percutaneous endoscopic), 0CBM7ZZ (via natural or artificial opening) and 0CBM8ZZ (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.
