About 0NCX4ZZ

0NCX4ZZ is the ICD-10-PCS code for a extirpation procedure on the hyoid bone using a percutaneous endoscopic approach. In ICD-10-PCS, extirpation means taking or cutting out solid matter from a body part.

In plain terms, this corresponds to other incision of facial bone, the ICD-9-CM procedure title it maps to (76.09).

For a different body part, codes include 0NC14ZZ (frontal bone), 0NC34ZZ (right parietal bone), 0NC44ZZ (left parietal bone), 0NC54ZZ (right temporal bone), 0NC64ZZ (left temporal bone), 0NC74ZZ (occipital bone) and 15 more.

The same procedure with a different approach is coded 0NCX0ZZ (open) and 0NCX3ZZ (percutaneous).

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.
