About BQ280ZZ
BQ280ZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the left knee using a high 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 BQ200ZZ (right hip), BQ210ZZ (left hip), BQ230ZZ (right femur), BQ240ZZ (left femur), BQ270ZZ (right knee), BQ2B0ZZ (right tibia/fibula) and 17 more.
The same procedure with a different approach is coded BQ281ZZ (low osmolar), BQ28YZZ (other contrast) and BQ28ZZZ (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.
