About B0281ZZ

B0281ZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the cerebral ventricle(s) using a low osmolar 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 B0201ZZ (brain), B0271ZZ (cisterna), B0291ZZ (sella turcica/pituitary gland) and B02B1ZZ (spinal cord).

The same procedure with a different approach is coded B0280ZZ (high osmolar), B028YZZ (other contrast) and B028ZZZ (none).

With a different device, use B02810Z (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.
