About 0NBR3ZX

0NBR3ZX is the ICD-10-PCS code for a excision procedure on the maxilla using a percutaneous approach (qualifier: diagnostic). In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to biopsy of alveolus and biopsy of facial bone, the ICD-9-CM procedure titles it maps to (24.12 and 76.11).

For a different body part, codes include 0NB03ZX (skull), 0NB13ZX (frontal bone), 0NB33ZX (right parietal bone), 0NB43ZX (left parietal bone), 0NB53ZX (right temporal bone), 0NB63ZX (left temporal bone) and 16 more.

The same procedure with a different approach is coded 0NBR0ZX (open) and 0NBR4ZX (percutaneous endoscopic).

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.
