About BW2F1ZZ

BW2F1ZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the neck 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 other computerized axial tomography, the ICD-9-CM procedure title it maps to (88.38).

For a different body part, codes include BW201ZZ (abdomen), BW211ZZ (abdomen and pelvis), BW241ZZ (chest and abdomen), BW251ZZ (chest, abdomen and pelvis), BW281ZZ (head), BW291ZZ (head and neck) and 1 more.

The same procedure with a different approach is coded BW2F0ZZ (high osmolar), BW2FYZZ (other contrast) and BW2FZZZ (none).

With a different device, use BW2F10Z (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.
