About BN190ZZ

BN190ZZ is the ICD-10-PCS code for a fluoroscopy procedure on the bilateral temporomandibular joints using a high 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 BN170ZZ (right temporomandibular joint) and BN180ZZ (left temporomandibular joint).

The same procedure with a different approach is coded BN191ZZ (low 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.
