About B029Y0Z

B029Y0Z is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the sella turcica/pituitary gland using an other contrast 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 Pneumoencephalogram, the ICD-9-CM procedure title it maps to (87.01).

For a different body part, codes include B020Y0Z (brain), B027Y0Z (cisterna), B028Y0Z (cerebral ventricle(s)) and B02BY0Z (spinal cord).

The same procedure with a different approach is coded B02900Z (high osmolar) and B02910Z (low osmolar).

With a different device, use B029YZZ (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.
