About BW2800Z

BW2800Z is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the head 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 BW2000Z (abdomen), BW2100Z (abdomen and pelvis), BW2400Z (chest and abdomen), BW2500Z (chest, abdomen and pelvis), BW2900Z (head and neck), BW2F00Z (neck) and 1 more.

The same procedure with a different approach is coded BW2810Z (low osmolar) and BW28Y0Z (other contrast).

With a different device, use BW280ZZ (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.
