About BN2FZZZ

BN2FZZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the temporal bones 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 BN29ZZZ (bilateral temporomandibular joints).

The same procedure with a different approach is coded BN2F0ZZ (high osmolar), BN2F1ZZ (low osmolar) and BN2FYZZ (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.
