About 0NCB4ZZ
0NCB4ZZ is the ICD-10-PCS code for a extirpation procedure on the nasal 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 incision of nose, the ICD-9-CM procedure title it maps to (21.1).
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 0NCB0ZZ (open) and 0NCB3ZZ (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.
