About 0NRX0KZ

0NRX0KZ is the ICD-10-PCS code for a replacement procedure on the hyoid bone 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 bone graft to facial bone, the ICD-9-CM procedure title it maps to (76.91).

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 0NRX3KZ (percutaneous) and 0NRX4KZ (percutaneous endoscopic).

With a different device, use 0NRX07Z (autologous tissue substitute) and 0NRX0JZ (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.
