About 0NUM0KZ

0NUM0KZ is the ICD-10-PCS code for a supplement procedure on the right zygomatic bone using an open approach with nonautologous tissue 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 bone graft to facial bone, the ICD-9-CM procedure title it maps to (76.91).

For a different body part, codes include 0NU00KZ (skull), 0NU10KZ (frontal bone), 0NU30KZ (right parietal bone), 0NU40KZ (left parietal bone), 0NU50KZ (right temporal bone), 0NU60KZ (left temporal bone) and 16 more.

The same procedure with a different approach is coded 0NUM3KZ (percutaneous) and 0NUM4KZ (percutaneous endoscopic).

With a different device, use 0NUM07Z (autologous tissue substitute) and 0NUM0JZ (synthetic 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) 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.
