About BN2FYZZ

BN2FYZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the temporal bones using an other contrast 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 BN20YZZ (skull), BN23YZZ (bilateral orbits), BN25YZZ (facial bones), BN26YZZ (mandible) and BN29YZZ (bilateral temporomandibular joints).

The same procedure with a different approach is coded BN2F0ZZ (high osmolar), BN2F1ZZ (low osmolar) and BN2FZZZ (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.
