About 0C9R40Z

0C9R40Z is the ICD-10-PCS code for a drainage procedure on the epiglottis using a percutaneous endoscopic approach with drainage device. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to other incision of larynx or trachea, the ICD-9-CM procedure title it maps to (31.3).

For a different body part, codes include 0C9M40Z (pharynx), 0C9S40Z (larynx), 0C9T40Z (right vocal cord) and 0C9V40Z (left vocal cord).

The same procedure with a different approach is coded 0C9R00Z (open), 0C9R30Z (percutaneous), 0C9R70Z (via natural or artificial opening) and 0C9R80Z (via natural or artificial opening endoscopic).

With a different device, use 0C9R4ZZ (no device).

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) and DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), under the surgical category “Other Ear, Nose, Mouth and Throat O.R. Procedures”.

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