About BN00ZZZ
BN00ZZZ is the ICD-10-PCS code for a plain radiography procedure on the skull using a none approach with none (qualifier: none). In ICD-10-PCS, plain radiography means planar display of an image developed from the capture of external ionizing radiation on photographic or photoconductive plate.
In plain terms, this corresponds to other x-ray of skull, the ICD-9-CM procedure title it maps to (87.17).
For a different body part, codes include BN01ZZZ (right orbit), BN02ZZZ (left orbit), BN03ZZZ (bilateral orbits), BN04ZZZ (nasal bones), BN05ZZZ (facial bones), BN06ZZZ (mandible) and 9 more.
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.
