About 0NBP4ZX

0NBP4ZX is the ICD-10-PCS code for a excision procedure on the right orbit using a percutaneous endoscopic 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 eyeball and orbit, the ICD-9-CM procedure title it maps to (16.23).

For a different body part, codes include 0NB04ZX (skull), 0NB14ZX (frontal bone), 0NB34ZX (right parietal bone), 0NB44ZX (left parietal bone), 0NB54ZX (right temporal bone), 0NB64ZX (left temporal bone) and 16 more.

The same procedure with a different approach is coded 0NBP0ZX (open) and 0NBP3ZX (percutaneous).

It is an operating-room procedure in the MS-DRG logic for DRG 113 (Orbital Procedures with CC/MCC) and DRG 114 (Orbital Procedures without CC/MCC), under the surgical category “Orbital Procedures”.

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