About BW240ZZ

BW240ZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the chest and abdomen using a high 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 thorax and computerized axial tomography of abdomen, the ICD-9-CM procedure titles it maps to (87.41 and 88.01).

For a different body part, codes include BW200ZZ (abdomen), BW210ZZ (abdomen and pelvis), BW250ZZ (chest, abdomen and pelvis), BW280ZZ (head), BW290ZZ (head and neck), BW2F0ZZ (neck) and 1 more.

The same procedure with a different approach is coded BW241ZZ (low osmolar), BW24YZZ (other contrast) and BW24ZZZ (none).

With a different device, use BW2400Z (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.
