CPT code 75833: Renal venography, bilateral imaging and interpretation2026 Medicare rate & RVUs in California

Medicare pays $163.75–$203.15 for 75833 in the office in California, from Chico, CA to San Benito County, CA. Which amount applies depends on the service address.

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

What 75833 covers

This service covers x-ray imaging and physician interpretation of the veins draining both kidneys, usually during a catheter-based diagnostic evaluation. A radiologist or other qualified physician assesses the contrast images for findings such as impaired venous flow, obstruction, or abnormal venous anatomy. It may be performed when renal vein disease is suspected or when venous anatomy must be defined for treatment planning.

Select the bilateral code when both renal venous systems are imaged; the unilateral counterpart is 75831. The record should support the clinical reason for imaging, the bilateral examination, and the physician’s interpretation. The code has professional and technical components: modifier 26 identifies interpretation, modifier TC identifies the equipment and staff service, and no component modifier represents the global service. The technical component is subject to the cardiovascular diagnostic multiple procedure reduction when applicable. The code is priced as bilateral, so modifier 50 does not increase payment.
