About BR291ZZ

BR291ZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the lumbar spine 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 BR201ZZ (cervical spine), BR271ZZ (thoracic spine), BR2C1ZZ (pelvis), BR2D1ZZ (sacroiliac joints) and BR2F1ZZ (sacrum and coccyx).

The same procedure with a different approach is coded BR290ZZ (high osmolar), BR29YZZ (other contrast) and BR29ZZZ (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.
