About 0NRT0KZ
0NRT0KZ is the ICD-10-PCS code for a replacement procedure on the right mandible using an open approach with nonautologous tissue substitute. In ICD-10-PCS, replacement means putting in or on biological or synthetic material that physically takes the place and/or function of all or a portion of a body part.
In plain terms, this corresponds to total mandibulectomy with synchronous reconstruction, the ICD-9-CM procedure title it maps to (76.41).
For a different body part, codes include 0NR00KZ (skull), 0NR10KZ (frontal bone), 0NR30KZ (right parietal bone), 0NR40KZ (left parietal bone), 0NR50KZ (right temporal bone), 0NR60KZ (left temporal bone) and 16 more.
The same procedure with a different approach is coded 0NRT3KZ (percutaneous) and 0NRT4KZ (percutaneous endoscopic).
With a different device, use 0NRT07Z (autologous tissue substitute) and 0NRT0JZ (synthetic substitute).
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. 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 “Major Head and Neck 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.
