About BB24Y0Z
BB24Y0Z is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the bilateral lungs using an other contrast 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 thorax, the ICD-9-CM procedure title it maps to (87.41).
For a different body part, codes include BB27Y0Z (right tracheobronchial tree), BB28Y0Z (left tracheobronchial tree), BB29Y0Z (bilateral tracheobronchial trees) and BB2FY0Z (trachea/airways).
The same procedure with a different approach is coded BB2400Z (high osmolar) and BB2410Z (low osmolar).
With a different device, use BB24YZZ (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.
