About 0NBV0ZX

0NBV0ZX is the ICD-10-PCS code for a excision procedure on the left mandible using an open 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 0NB00ZX (skull), 0NB10ZX (frontal bone), 0NB30ZX (right parietal bone), 0NB40ZX (left parietal bone), 0NB50ZX (right temporal bone), 0NB60ZX (left temporal bone) and 16 more.

The same procedure with a different approach is coded 0NBV3ZX (percutaneous) and 0NBV4ZX (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.
