CPT code 75880: Orbital venography, orbital veins2026 Medicare rate & RVUs in California

Medicare pays $112.40–$142.36 for 75880 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 75880 covers

This service covers the physician’s supervision and interpretation of contrast imaging that demonstrates the veins within the orbit. It may be performed during a diagnostic evaluation of suspected orbital venous abnormality. A radiologist, often one working in a hospital or interventional radiology setting, reviews the images and documents the findings; the code is specific to orbital veins rather than veins of the skull, neck, or limbs.

Report 75880 when the documented study images orbital veins and the physician provides the corresponding interpretation. The report should identify the anatomy examined and describe the imaging findings. CMS recognizes professional and technical components: use modifier 26 for the interpretation, modifier TC for equipment and staff, or report the global service without either modifier. The cardiovascular diagnostic multiple-procedure reduction applies to the technical component when applicable; it does not identify a reduction to the professional component.
