About BG241ZZ
BG241ZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the thyroid gland 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 BG221ZZ (bilateral adrenal glands) and BG231ZZ (parathyroid glands).
The same procedure with a different approach is coded BG240ZZ (high osmolar), BG24YZZ (other contrast) and BG24ZZZ (none).
With a different device, use BG2410Z (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.
