About BU41ZZZ

BU41ZZZ is the ICD-10-PCS code for a ultrasonography procedure on the left fallopian tube 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 other diagnostic ultrasound, the ICD-9-CM procedure title it maps to (88.79).

For a different body part, codes include BU40ZZZ (right fallopian tube), BU42ZZZ (bilateral fallopian tubes), BU43ZZZ (right ovary), BU44ZZZ (left ovary), BU45ZZZ (bilateral ovaries), BU46ZZZ (uterus) and 1 more.

The same procedure with a different approach is coded BU41YZZ (other contrast).

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.
