About B027YZZ

B027YZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the cisterna 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 contrast radiogram of brain and skull, the ICD-9-CM procedure title it maps to (87.02).

For a different body part, codes include B020YZZ (brain), B028YZZ (cerebral ventricle(s)), B029YZZ (sella turcica/pituitary gland) and B02BYZZ (spinal cord).

The same procedure with a different approach is coded B0270ZZ (high osmolar), B0271ZZ (low osmolar) and B027ZZZ (none).

With a different device, use B027Y0Z (unenhanced and enhanced).

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.
