About the B34 Code Range
These procedures use high-frequency sound waves to display live images of upper arteries or blood flow.
The fourth character identifies the artery or arterial group, including the thoracic aorta, carotid, upper extremity, intracranial, pulmonary and ophthalmic arteries. It distinguishes right, left and bilateral sites where those values are listed. The fifth character indicates no contrast, and the sixth has no qualifier. The seventh distinguishes Intravascular from no qualifier.
