About B446ZZ3

B446ZZ3 is the ICD-10-PCS code for a ultrasonography procedure on the right renal artery using a none approach with none (qualifier: intravascular). 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 intravascular imaging of renal vessels, the ICD-9-CM procedure title it maps to (00.25).

For a different body part, codes include B440ZZ3 (abdominal aorta), B444ZZ3 (superior mesenteric artery), B445ZZ3 (inferior mesenteric artery), B447ZZ3 (left renal artery), B448ZZ3 (bilateral renal arteries), B44BZZ3 (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.
