About 0RGC04Z

0RGC04Z is the ICD-10-PCS code for a fusion procedure on the right temporomandibular joint using an open approach with internal fixation device. In ICD-10-PCS, fusion means joining together portions of an articular body part rendering the articular body part immobile.

In plain terms, this corresponds to other operations on facial bones and joints, the ICD-9-CM procedure title it maps to (76.99).

For a different body part, codes include 0RGD04Z (left temporomandibular joint), 0RGE04Z (right sternoclavicular joint), 0RGF04Z (left sternoclavicular joint), 0RGG04Z (right acromioclavicular joint), 0RGH04Z (left acromioclavicular joint), 0RGJ04Z (right shoulder joint) and 13 more.

The same procedure with a different approach is coded 0RGC34Z (percutaneous) and 0RGC44Z (percutaneous endoscopic).

With a different device, use 0RGC07Z (autologous tissue substitute), 0RGC0JZ (synthetic substitute) and 0RGC0KZ (nonautologous tissue substitute).

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 515 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with MCC), DRG 516 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with CC) and DRG 517 (Other Musculoskeletal System and Connective Tissue O.R. Procedures without CC/MCC), under the surgical categories “Other Ear, Nose, Mouth and Throat O.R. Procedures”, “Other Musculoskeletal System and Connective Tissue O.R. Procedures”, “Other O.R. Procedures for Injuries” and 1 more.

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