About BT4JZZZ
BT4JZZZ is the ICD-10-PCS code for a ultrasonography procedure on the kidneys and bladder using a none approach with none (qualifier: none). In ICD-10-PCS, ultrasonography means real time display of images of anatomy or flow information developed from the capture of reflected and attenuated high frequency sound waves.
In plain terms, this corresponds to diagnostic ultrasound of urinary system, the ICD-9-CM procedure title it maps to (88.75).
For a different body part, codes include BT40ZZZ (bladder), BT41ZZZ (right kidney), BT42ZZZ (left kidney), BT43ZZZ (bilateral kidneys), BT45ZZZ (urethra), BT46ZZZ (right ureter) and 3 more.
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.
