About 0NCR4ZZ

0NCR4ZZ is the ICD-10-PCS code for a extirpation procedure on the maxilla 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 incision of gum or alveolar bone and other incision of facial bone, the ICD-9-CM procedure titles it maps to (24.0 and 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 0NCR0ZZ (open) and 0NCR3ZZ (percutaneous).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

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