About B522Y0Z

B522Y0Z is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the intracranial sinuses 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 other computerized axial tomography, the ICD-9-CM procedure title it maps to (88.38).

For a different body part, codes include B528Y0Z (superior vena cava), B529Y0Z (inferior vena cava), B52FY0Z (right pelvic (iliac) veins), B52GY0Z (left pelvic (iliac) veins), B52HY0Z (bilateral pelvic (iliac) veins), B52JY0Z (right renal vein) and 6 more.

The same procedure with a different approach is coded B52200Z (high osmolar) and B52210Z (low osmolar).

With a different device, use B522YZZ (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.
