About BT021ZZ
BT021ZZ is the ICD-10-PCS code for a plain radiography procedure on the left kidney using a low osmolar approach with none (qualifier: none). In ICD-10-PCS, plain radiography means planar display of an image developed from the capture of external ionizing radiation on photographic or photoconductive plate.
In plain terms, this corresponds to other nephrotomogram, the ICD-9-CM procedure title it maps to (87.72).
For a different body part, codes include BT001ZZ (bladder), BT011ZZ (right kidney), BT031ZZ (bilateral kidneys), BT041ZZ (kidneys, ureters and bladder), BT051ZZ (urethra), BT061ZZ (right ureter) and 4 more.
The same procedure with a different approach is coded BT020ZZ (high osmolar), BT02YZZ (other contrast) and BT02ZZZ (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.
