About BN29ZZZ
BN29ZZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the bilateral temporomandibular joints using a none 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 BN20ZZZ (skull), BN23ZZZ (bilateral orbits), BN25ZZZ (facial bones), BN26ZZZ (mandible) and BN2FZZZ (temporal bones).
The same procedure with a different approach is coded BN290ZZ (high osmolar), BN291ZZ (low osmolar) and BN29YZZ (other contrast).
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.
