Digital Subtraction Angiography (DSA)
Digital subtraction angiography (DSA) is a diagnostic imaging technique that applies computer technology
to fluoroscopy for the purpose of visualizing the same vascular structures observable with conventional
angiography. Since the radiographic contrast material can be injected into a vein rather than an artery, the
procedure reduces the risk to patients, and can be done on an outpatient basis.
A/B MACs (A) and (B) should be alert to possible increases in utilization of DSA over conventional
angiographic procedures, as well as to the fact that ordinarily patients should not require inpatient
hospitalization solely to perform the procedure.
Payment for DSA should not exceed, and may be less than, that being paid for conventional angiographic
techniques.
