About 78458: Bilateral venous thrombosis imaging
Bilateral venous thrombosis imaging evaluates venous flow and possible thrombus in both sides when a nuclear medicine study is performed.
This nuclear medicine study images venous flow and possible thrombus on both sides, commonly in the lower extremities when bilateral venous thrombosis is being evaluated. A nuclear medicine or radiology physician interprets the images; the technical service involves the equipment and staff used to perform the study. The report should identify the areas examined and document the interpretation of the bilateral findings.
Report 78458 when the service performed is bilateral venous thrombosis imaging, rather than a single-side study. The code is already priced as bilateral, so modifier 50 does not increase payment. Bill the global service without a component modifier, or separate the interpretation with modifier 26 and the technical service with modifier TC. When the cardiovascular diagnostic multiple procedure reduction applies, it affects the technical component. Documentation should support that both sides were imaged and include the interpreting physician’s findings.

78458 billing questions
When should 78458 be chosen over 78457?
Use 78458 for a bilateral venous thrombosis imaging study. Use 78457 when the study is for a single side.
Should modifier 50 be appended for a bilateral study?
No. 78458 is priced as bilateral, and modifier 50 does not increase payment.
Can the interpretation and technical service be billed separately?
Yes. Report modifier 26 for the professional interpretation or modifier TC for the technical service. Without either modifier, the claim represents the global service.
Which part of the service is subject to the multiple procedure reduction?
The cardiovascular diagnostic multiple procedure reduction applies to the technical component. It does not change the component designation of the professional interpretation.
What documentation supports reporting 78458?
Document that the bilateral study was performed, which areas were imaged, and the interpreting physician’s findings. The record should support bilateral rather than single-side 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 indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
