About BT2310Z
BT2310Z is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the bilateral kidneys using a low osmolar 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 BT2010Z (bladder), BT2110Z (right kidney), BT2210Z (left kidney) and BT2910Z (kidney transplant).
The same procedure with a different approach is coded BT2300Z (high osmolar) and BT23Y0Z (other contrast).
With a different device, use BT231ZZ (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.
