About 0RTC0ZZ

0RTC0ZZ is the ICD-10-PCS code for a resection procedure on the right temporomandibular joint using an open approach. In ICD-10-PCS, resection means cutting out or off, without replacement, all of a body part.

In plain terms, this corresponds to other total ostectomy of other facial bone, the ICD-9-CM procedure title it maps to (76.45).

It is an operating-room procedure in the MS-DRG logic for DRG 140 (Major Head and Neck Procedures with MCC), DRG 141 (Major Head and Neck Procedures with CC), DRG 142 (Major Head and Neck Procedures without CC/MCC), DRG 515 (Other Musculoskeletal System and Connective Tissue O.R.
