About 0NUM4JZ

0NUM4JZ is the ICD-10-PCS code for a supplement procedure on the right zygomatic bone using a percutaneous endoscopic approach with synthetic substitute. In ICD-10-PCS, supplement means putting in or on biological or synthetic material that physically reinforces and/or augments the function of a portion of a body part.

In plain terms, this corresponds to insertion of synthetic implant in facial bone, the ICD-9-CM procedure title it maps to (76.92).

For a different body part, codes include 0NU04JZ (skull), 0NU14JZ (frontal bone), 0NU34JZ (right parietal bone), 0NU44JZ (left parietal bone), 0NU54JZ (right temporal bone), 0NU64JZ (left temporal bone) and 16 more.

The same procedure with a different approach is coded 0NUM0JZ (open) and 0NUM3JZ (percutaneous).

With a different device, use 0NUM47Z (autologous tissue substitute) and 0NUM4KZ (nonautologous tissue substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 113 (Orbital Procedures with CC/MCC), DRG 114 (Orbital Procedures without CC/MCC), 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) and DRG 515 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with MCC), under the surgical categories “Orbital Procedures”, “Other Ear, Nose, Mouth and Throat O.R. Procedures”, “Other Musculoskeletal System and Connective Tissue O.R. Procedures” and 2 more.

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