CPT code 75870: Venography, intracranial venous sinuses2026 Medicare rate & RVUs

Medicare pays $184.04 for 75870 nationally in the office. Local office rates run $160.56–$245.81.

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

What 75870 covers

This service covers the physician’s radiological supervision and interpretation of contrast x-ray venography of intracranial venous sinuses. A radiologist or neurointerventional specialist may interpret the study when clinicians need to assess venous drainage or investigate suspected sinus thrombosis or obstruction. The anatomy is the venous sinuses within the skull, not the epidural venous plexus or veins of the neck.

Report the service for the interpretation of the venographic study, with documentation identifying the imaged sinuses, the contrast study performed, and the physician’s findings. The code has professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies the equipment and staff portion, and no modifier represents the global service. When multiple cardiovascular diagnostic procedures are performed, the multiple procedure reduction applies to the technical component.
