About BB29ZZZ

BB29ZZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the bilateral tracheobronchial trees using a none 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 BB24ZZZ (bilateral lungs), BB27ZZZ (right tracheobronchial tree), BB28ZZZ (left tracheobronchial tree) and BB2FZZZ (trachea/airways).

The same procedure with a different approach is coded BB290ZZ (high osmolar), BB291ZZ (low osmolar) and BB29YZZ (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.
