About BH42ZZZ

BH42ZZZ is the ICD-10-PCS code for a ultrasonography procedure on the bilateral breasts 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 other sites of thorax, the ICD-9-CM procedure title it maps to (88.73).

For a different body part, codes include BH40ZZZ (right breast), BH41ZZZ (left breast), BH47ZZZ (extremity, upper), BH48ZZZ (extremity, lower), BH49ZZZ (abdominal wall), BH4BZZZ (chest wall) and 1 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.
