About BB28Y0Z

BB28Y0Z is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the left tracheobronchial tree 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 other computerized axial tomography, the ICD-9-CM procedure title it maps to (88.38).

For a different body part, codes include BB24Y0Z (bilateral lungs), BB27Y0Z (right tracheobronchial tree), BB29Y0Z (bilateral tracheobronchial trees) and BB2FY0Z (trachea/airways).

The same procedure with a different approach is coded BB2800Z (high osmolar) and BB2810Z (low osmolar).

With a different device, use BB28YZZ (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.
