About B445ZZZ

B445ZZZ is the ICD-10-PCS code for a ultrasonography procedure on the inferior mesenteric artery 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 peripheral vascular system, the ICD-9-CM procedure title it maps to (88.77).

For a different body part, codes include B440ZZZ (abdominal aorta), B444ZZZ (superior mesenteric artery), B446ZZZ (right renal artery), B447ZZZ (left renal artery), B448ZZZ (bilateral renal arteries), B44BZZZ (intra-abdominal arteries, other) and 6 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.
