About 0R9C40Z
0R9C40Z is the ICD-10-PCS code for a drainage procedure on the right temporomandibular joint 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 facial bone, the ICD-9-CM procedure title it maps to (76.09).
For a different body part, codes include 0R9040Z (occipital-cervical joint), 0R9140Z (cervical vertebral joint), 0R9340Z (cervical vertebral disc), 0R9440Z (cervicothoracic vertebral joint), 0R9540Z (cervicothoracic vertebral disc), 0R9640Z (thoracic vertebral joint) and 22 more.
The same procedure with a different approach is coded 0R9C00Z (open) and 0R9C30Z (percutaneous).
With a different device, use 0R9C4ZZ (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.
