About BT220ZZ
BT220ZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the left kidney 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 computerized axial tomography of kidney, the ICD-9-CM procedure title it maps to (87.71).
For a different body part, codes include BT200ZZ (bladder), BT210ZZ (right kidney), BT230ZZ (bilateral kidneys) and BT290ZZ (kidney transplant).
The same procedure with a different approach is coded BT221ZZ (low osmolar), BT22YZZ (other contrast) and BT22ZZZ (none).
With a different device, use BT2200Z (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.
