About B020YZZ

B020YZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the brain 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 Pneumoencephalogram and computerized axial tomography of head, the ICD-9-CM procedure titles it maps to (87.01 and 87.03).

For a different body part, codes include B027YZZ (cisterna), B028YZZ (cerebral ventricle(s)), B029YZZ (sella turcica/pituitary gland) and B02BYZZ (spinal cord).

The same procedure with a different approach is coded B0200ZZ (high osmolar), B0201ZZ (low osmolar) and B020ZZZ (none).

With a different device, use B020Y0Z (unenhanced and enhanced).

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.
