CPT code 75891: Hepatic venography, liver venous study2026 Medicare rate & RVUs in California

Medicare pays $130.10–$162.21 for 75891 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 75891 covers

This service covers radiological supervision and interpretation of contrast x-ray imaging of veins in the liver. A radiologist interprets the images to assess hepatic venous anatomy and contrast flow, such as when clinicians investigate suspected abnormal venous drainage or obstruction. The study is typically performed in a hospital or other facility as part of a catheter-based diagnostic evaluation; the imaging professional service is distinct from the equipment and staff used to obtain the images.

Select the code that matches the hepatic venography actually performed, including whether the study includes hemodynamic evaluation and any other distinctions in the applicable code family. The report should identify the liver venous study and describe the interpretation; the procedure record supports the imaging performed. Bill globally when one entity provides both components, or use modifier 26 for interpretation and modifier TC for the technical service when those components are billed separately. The cardiovascular diagnostic multiple procedure reduction applies to the technical component.
