About B5220ZZ

B5220ZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the intracranial sinuses using a high osmolar 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 computerized axial tomography, the ICD-9-CM procedure title it maps to (88.38).

For a different body part, codes include B5280ZZ (superior vena cava), B5290ZZ (inferior vena cava), B52F0ZZ (right pelvic (iliac) veins), B52G0ZZ (left pelvic (iliac) veins), B52H0ZZ (bilateral pelvic (iliac) veins), B52J0ZZ (right renal vein) and 6 more.

The same procedure with a different approach is coded B5221ZZ (low osmolar), B522YZZ (other contrast) and B522ZZZ (none).

With a different device, use B52200Z (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.
