About BN290ZZ
BN290ZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the bilateral temporomandibular joints using a high osmolar approach with none (qualifier: none). In ICD-10-PCS, computerized tomography (CT scan) means computer reformatted digital display of multiplanar images developed from the capture of multiple exposures of external ionizing radiation.
In plain terms, this corresponds to computerized axial tomography of head, the ICD-9-CM procedure title it maps to (87.03).
For a different body part, codes include BN200ZZ (skull), BN230ZZ (bilateral orbits), BN250ZZ (facial bones), BN260ZZ (mandible) and BN2F0ZZ (temporal bones).
The same procedure with a different approach is coded BN291ZZ (low osmolar), BN29YZZ (other contrast) and BN29ZZZ (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.
