About BN091ZZ
BN091ZZ is the ICD-10-PCS code for a plain radiography procedure on the bilateral temporomandibular joints using a low osmolar 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 temporomandibular contrast arthrogram, the ICD-9-CM procedure title it maps to (87.13).
For a different body part, codes include BN071ZZ (right temporomandibular joint) and BN081ZZ (left temporomandibular joint).
The same procedure with a different approach is coded BN090ZZ (high osmolar), BN09YZZ (other contrast) and BN09ZZZ (none).
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.
