About BG23YZZ
BG23YZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the parathyroid glands using an other contrast 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 BG22YZZ (bilateral adrenal glands) and BG24YZZ (thyroid gland).
The same procedure with a different approach is coded BG230ZZ (high osmolar), BG231ZZ (low osmolar) and BG23ZZZ (none).
With a different device, use BG23Y0Z (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.
