About BQ2W1ZZ
BQ2W1ZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the left patella using a low osmolar 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 BQ201ZZ (right hip), BQ211ZZ (left hip), BQ231ZZ (right femur), BQ241ZZ (left femur), BQ271ZZ (right knee), BQ281ZZ (left knee) and 17 more.
The same procedure with a different approach is coded BQ2W0ZZ (high osmolar), BQ2WYZZ (other contrast) and BQ2WZZZ (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.
