Medicare pays $113.56 for 75825 nationally in the office. Local office rates run $101.17–$147.21.

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

What 75825 covers

This service covers radiographic imaging and interpretation of the inferior vena cava after contrast is introduced into the venous system, often with serial images to assess caval patency, narrowing, obstruction, or thrombus. Interventional radiologists and diagnostic radiologists commonly perform or interpret the study in a hospital imaging department or catheterization suite. A typical setting is cavography performed in connection with evaluation for an inferior vena cava filter or during a filter procedure; the code represents the imaging service, not filter placement itself.

Select the code when the imaged structure is the inferior vena cava, rather than a limb vein, renal vein, or superior vena cava. The report should identify the target anatomy, contrast imaging performed, and the radiologist’s findings and interpretation. Bill the global service without a component modifier, or report the professional interpretation with modifier 26 and the equipment and staff portion with modifier TC. When multiple cardiovascular diagnostic procedures are performed, the multiple-procedure reduction applies to the technical component.
