Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 75635 covers

This examination uses contrast-enhanced CT to depict the abdominal aorta and arterial circulation through both lower extremities. It is commonly used to assess aortoiliac or peripheral arterial disease, including suspected stenosis or occlusion, and to map vascular anatomy before treatment planning. A technologist acquires the images; a radiologist or other qualified physician interprets them. Noncontrast images, when obtained, and image postprocessing are included in the CTA service.

Report one unit for the combined examination, not a separate unit per leg. The order, clinical indication, documented anatomic coverage, and physician interpretation should support the study. When one entity bills for the complete service, report without a component modifier; use modifier 26 for the professional interpretation or TC for the technical service when those portions are billed separately. CMS applies the diagnostic imaging multiple procedure reduction to both the technical and professional components.
