About B02000Z

B02000Z is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the brain using a high osmolar approach with unenhanced and enhanced (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 B02700Z (cisterna), B02800Z (cerebral ventricle(s)), B02900Z (sella turcica/pituitary gland) and B02B00Z (spinal cord).

The same procedure with a different approach is coded B02010Z (low osmolar) and B020Y0Z (other contrast).

With a different device, use B0200ZZ (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.
