About BT23Y0Z
BT23Y0Z is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the bilateral kidneys 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 computerized axial tomography of kidney, the ICD-9-CM procedure title it maps to (87.71).
For a different body part, codes include BT20Y0Z (bladder), BT21Y0Z (right kidney), BT22Y0Z (left kidney) and BT29Y0Z (kidney transplant).
The same procedure with a different approach is coded BT2300Z (high osmolar) and BT2310Z (low osmolar).
With a different device, use BT23YZZ (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.
