About 0CTS4ZZ

0CTS4ZZ is the ICD-10-PCS code for a resection procedure on the larynx using a percutaneous endoscopic approach. In ICD-10-PCS, resection means cutting out or off, without replacement, all of a body part.

In plain terms, this corresponds to complete laryngectomy, the ICD-9-CM procedure title it maps to (30.3).

For a different body part, codes include 0CTM4ZZ (pharynx), 0CTR4ZZ (epiglottis), 0CTT4ZZ (right vocal cord) and 0CTV4ZZ (left vocal cord).

The same procedure with a different approach is coded 0CTS0ZZ (open), 0CTS7ZZ (via natural or artificial opening) and 0CTS8ZZ (via natural or artificial opening endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 011 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with MCC), DRG 012 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with CC) and DRG 013 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy without CC/MCC), under the surgical category “Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy”.

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