About 0C9T0ZX

0C9T0ZX is the ICD-10-PCS code for a drainage procedure on the right vocal cord using an open approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to open biopsy of larynx or trachea, the ICD-9-CM procedure title it maps to (31.45).

For a different body part, codes include 0C900ZX (upper lip), 0C910ZX (lower lip), 0C920ZX (hard palate), 0C930ZX (soft palate), 0C940ZX (buccal mucosa), 0C950ZX (upper gingiva) and 18 more.

The same procedure with a different approach is coded 0C9T3ZX (percutaneous), 0C9T4ZX (percutaneous endoscopic), 0C9T7ZX (via natural or artificial opening) and 0C9T8ZX (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 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 “Other Ear, Nose, Mouth and Throat O.R. Procedures” and “Other Respiratory System O.R. Procedures”.

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