About B8271ZZ

B8271ZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the bilateral eyes 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 B8251ZZ (right eye) and B8261ZZ (left eye).

The same procedure with a different approach is coded B8270ZZ (high osmolar), B827YZZ (other contrast) and B827ZZZ (none).

With a different device, use B82710Z (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.
