About B029YZZ

B029YZZ 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 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 Pneumoencephalogram, the ICD-9-CM procedure title it maps to (87.01).

For a different body part, codes include B020YZZ (brain), B027YZZ (cisterna), B028YZZ (cerebral ventricle(s)) and B02BYZZ (spinal cord).

The same procedure with a different approach is coded B0290ZZ (high osmolar), B0291ZZ (low osmolar) and B029ZZZ (none).

With a different device, use B029Y0Z (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.
