About 0RHC04Z
0RHC04Z is the ICD-10-PCS code for a insertion procedure on the right temporomandibular joint using an open approach with internal fixation device. In ICD-10-PCS, insertion means putting in a nonbiological appliance that monitors, assists, performs, or prevents a physiological function but does not physically take the place of 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 0RH004Z (occipital-cervical joint), 0RH104Z (cervical vertebral joint), 0RH404Z (cervicothoracic vertebral joint), 0RH604Z (thoracic vertebral joint), 0RHA04Z (thoracolumbar vertebral joint), 0RHD04Z (left temporomandibular joint) and 18 more.
The same procedure with a different approach is coded 0RHC34Z (percutaneous) and 0RHC44Z (percutaneous endoscopic).
With a different device, use 0RHC03Z (infusion device) and 0RHC08Z (spacer).
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.
