About BQ28YZZ
BQ28YZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the left knee using an other contrast 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 BQ20YZZ (right hip), BQ21YZZ (left hip), BQ23YZZ (right femur), BQ24YZZ (left femur), BQ27YZZ (right knee), BQ2BYZZ (right tibia/fibula) and 17 more.
The same procedure with a different approach is coded BQ280ZZ (high osmolar), BQ281ZZ (low osmolar) 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.
