About BW21ZZZ

BW21ZZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the abdomen and pelvis 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 BW20ZZZ (abdomen), BW24ZZZ (chest and abdomen), BW25ZZZ (chest, abdomen and pelvis), BW28ZZZ (head), BW29ZZZ (head and neck), BW2FZZZ (neck) and 1 more.

The same procedure with a different approach is coded BW210ZZ (high osmolar), BW211ZZ (low osmolar) and BW21YZZ (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.
