About BP2W1ZZ

BP2W1ZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the thorax 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 thorax, the ICD-9-CM procedure title it maps to (87.41).

For a different body part, codes include BP201ZZ (right sternoclavicular joint), BP211ZZ (left sternoclavicular joint), BP221ZZ (bilateral sternoclavicular joints), BP231ZZ (bilateral acromioclavicular joints), BP241ZZ (right clavicle), BP251ZZ (left clavicle) and 24 more.

The same procedure with a different approach is coded BP2W0ZZ (high osmolar) and BP2WYZZ (other contrast).

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.
