About BB28YZZ

BB28YZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the left tracheobronchial tree using an other contrast 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 BB24YZZ (bilateral lungs), BB27YZZ (right tracheobronchial tree), BB29YZZ (bilateral tracheobronchial trees) and BB2FYZZ (trachea/airways).

The same procedure with a different approach is coded BB280ZZ (high osmolar), BB281ZZ (low osmolar) and BB28ZZZ (none).

With a different device, use BB28Y0Z (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.
