About BW201ZZ

BW201ZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the abdomen 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 abdomen, the ICD-9-CM procedure title it maps to (88.01).

For a different body part, codes include BW211ZZ (abdomen and pelvis), BW241ZZ (chest and abdomen), BW251ZZ (chest, abdomen and pelvis), BW281ZZ (head), BW291ZZ (head and neck), BW2F1ZZ (neck) and 1 more.

The same procedure with a different approach is coded BW200ZZ (high osmolar), BW20YZZ (other contrast) and BW20ZZZ (none).

With a different device, use BW2010Z (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.
