About BN191ZZ
BN191ZZ is the ICD-10-PCS code for a fluoroscopy procedure on the bilateral temporomandibular joints using a low osmolar approach with none (qualifier: none). In ICD-10-PCS, fluoroscopy means single plane or bi-plane real time display of an image developed from the capture of external ionizing radiation on a fluorescent screen. The image may also be stored by either digital or analog means.
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 BN171ZZ (right temporomandibular joint) and BN181ZZ (left temporomandibular joint).
The same procedure with a different approach is coded BN190ZZ (high osmolar), BN19YZZ (other contrast) and BN19ZZZ (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.
