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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

75870 billing questions

How is this different from code 75872?

Code 75870 is for venous sinuses within the skull. Code 75872 is for imaging the epidural venous system.

Which modifier identifies the interpretation?

Use modifier 26 for the professional interpretation. Modifier TC identifies the technical component; billing without either modifier represents the global service.

Does a multiple procedure reduction affect this service?

The cardiovascular diagnostic multiple procedure reduction applies to the technical component when applicable. It does not reduce the professional component.

Does this code include catheter placement?

The code represents radiological supervision and interpretation of the venographic images. Document any separately reported catheter placement service and code it under the applicable rules.

Can this code describe CT or MR venous imaging?

No. This code is for x-ray venography of intracranial venous sinuses, not CT or MR venous imaging.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
