About 0NRR4KZ

0NRR4KZ is the ICD-10-PCS code for a replacement procedure on the maxilla using a percutaneous endoscopic 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 other facial bone repair, the ICD-9-CM procedure title it maps to (76.69).

For a different body part, codes include 0NR04KZ (skull), 0NR14KZ (frontal bone), 0NR34KZ (right parietal bone), 0NR44KZ (left parietal bone), 0NR54KZ (right temporal bone), 0NR64KZ (left temporal bone) and 16 more.

The same procedure with a different approach is coded 0NRR0KZ (open) and 0NRR3KZ (percutaneous).

With a different device, use 0NRR47Z (autologous tissue substitute) and 0NRR4JZ (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), DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Other Ear, Nose, Mouth and Throat O.R. Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

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