CPT code 0994T denotes a targeted endovascular procedure delivering drug therapy inside the aorta to stabilize an abdominal aortic aneurysm via a percutaneous approach. This procedure combines intraprocedural imaging, aortic roadmapping, balloon occlusion, and radiology supervision and interpretation, positioning it at the intersection of interventional radiology and vascular surgery. Nationally, the code matters because it captures a specialized, device- and imaging-intensive service used for patients with complex aortic pathology where open repair is not indicated or as an adjunct to endovascular aneurysm management.

Key payers reviewed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical intent and service components tied to the code, an overview of typical sites of service and operational considerations, and a summary of what to expect in payer coverage patterns and reimbursement benchmarking. The publication outlines clinical context for use, common billing and documentation themes relevant to interventional services, and highlights where additional policy detail or payer-specific guidance is commonly needed.
