About BQ2SZZZ
BQ2SZZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the left lower extremity 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 BQ20ZZZ (right hip), BQ21ZZZ (left hip), BQ23ZZZ (right femur), BQ24ZZZ (left femur), BQ27ZZZ (right knee), BQ28ZZZ (left knee) and 15 more.
The same procedure with a different approach is coded BQ2S0ZZ (high osmolar), BQ2S1ZZ (low osmolar) and BQ2SYZZ (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.
