About 0R9D4ZZ
0R9D4ZZ is the ICD-10-PCS code for a drainage procedure on the left temporomandibular joint using a percutaneous endoscopic approach. 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 0R904ZZ (occipital-cervical joint), 0R914ZZ (cervical vertebral joint), 0R934ZZ (cervical vertebral disc), 0R944ZZ (cervicothoracic vertebral joint), 0R954ZZ (cervicothoracic vertebral disc), 0R964ZZ (thoracic vertebral joint) and 22 more.
The same procedure with a different approach is coded 0R9D0ZZ (open) and 0R9D3ZZ (percutaneous).
With a different device, use 0R9D40Z (drainage 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.
