About BT201ZZ

BT201ZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the bladder using a low 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 BT211ZZ (right kidney), BT221ZZ (left kidney), BT231ZZ (bilateral kidneys) and BT291ZZ (kidney transplant).

The same procedure with a different approach is coded BT200ZZ (high osmolar), BT20YZZ (other contrast) and BT20ZZZ (none).

With a different device, use BT2010Z (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.
