About 0C9R00Z
0C9R00Z is the ICD-10-PCS code for a drainage procedure on the epiglottis using an open 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 0C9000Z (upper lip), 0C9100Z (lower lip), 0C9200Z (hard palate), 0C9300Z (soft palate), 0C9400Z (buccal mucosa), 0C9500Z (upper gingiva) and 18 more.
The same procedure with a different approach is coded 0C9R30Z (percutaneous), 0C9R40Z (percutaneous endoscopic), 0C9R70Z (via natural or artificial opening) and 0C9R80Z (via natural or artificial opening endoscopic).
With a different device, use 0C9R0ZZ (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.
