About 0CBS4ZZ

0CBS4ZZ is the ICD-10-PCS code for a excision procedure on the larynx using a percutaneous endoscopic 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 other excision or destruction of lesion or tissue of larynx and other partial laryngectomy, the ICD-9-CM procedure titles it maps to (30.09 and 30.29).

For a different body part, codes include 0CBM4ZZ (pharynx), 0CBR4ZZ (epiglottis), 0CBT4ZZ (right vocal cord) and 0CBV4ZZ (left vocal cord).

The same procedure with a different approach is coded 0CBS0ZZ (open), 0CBS3ZZ (percutaneous), 0CBS7ZZ (via natural or artificial opening) and 0CBS8ZZ (via natural or artificial opening endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 140 (Major Head and Neck Procedures with MCC), DRG 141 (Major Head and Neck Procedures with CC), DRG 142 (Major Head and Neck 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 “Major Head and Neck 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.
