CPT® Code 75898

Angiography through existing catheter for follow-up study for transcatheter therapy, embolization or infusion, other than for thrombolysis

The CPT® Code 75898 refers to the procedure of performing angiography through an existing catheter specifically for follow-up studies related to transcatheter therapy, embolization, or infusion, excluding thrombolysis. This procedure is essential for assessing the effectiveness of previously conducted transcatheter interventions. During this follow-up angiography, a contrast agent is injected through the catheter that was already placed during the initial procedure. This allows for the visualization of the treatment site through imaging techniques. The primary goal is to evaluate the outcomes of the transcatheter therapy, which may involve embolization—where blood vessels are intentionally blocked—or infusion—where medication is delivered directly to a specific area. The resulting images from this angiography will help determine if the desired therapeutic effects, such as the occlusion of targeted blood vessels in embolization or the successful delivery of medication in infusion, have been achieved. A comprehensive written interpretation of the angiographic findings is also provided to document the results of the follow-up study.
