About B02700Z

B02700Z is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the cisterna using a high 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 B02000Z (brain), B02800Z (cerebral ventricle(s)), B02900Z (sella turcica/pituitary gland) and B02B00Z (spinal cord).

The same procedure with a different approach is coded B02710Z (low osmolar) and B027Y0Z (other contrast).

With a different device, use B0270ZZ (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.
