About B02710Z

B02710Z is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the cisterna using a low osmolar approach with unenhanced and enhanced (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 computerized axial tomography of head, the ICD-9-CM procedure title it maps to (87.03).

For a different body part, codes include B02010Z (brain), B02810Z (cerebral ventricle(s)), B02910Z (sella turcica/pituitary gland) and B02B10Z (spinal cord).

The same procedure with a different approach is coded B02700Z (high osmolar) and B027Y0Z (other contrast).

With a different device, use B0271ZZ (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.
