About 78456: Acute venous thrombosis imaging
Nuclear medicine imaging to evaluate acute venous thrombosis, reported for a study focused on detecting an acute venous clot.
This nuclear medicine study evaluates suspected acute venous thrombosis by imaging for evidence of a clot. It may be performed in a hospital or imaging department by nuclear medicine staff, with a qualified practitioner interpreting the images. The clinical question is acute thrombus detection; this is distinct from studies specifically described as venous flow and pool imaging or bilateral venous thrombosis imaging.
Report the service when the study performed is an acute venous thrombosis imaging examination, rather than selecting a code based only on the suspected body site. The record should support the acute-thrombus indication and identify the imaging service performed. The code includes a professional interpretation and a technical service; report modifier 26 for interpretation, modifier TC for equipment and staff, or neither for the global service. When a cardiovascular diagnostic multiple procedure reduction applies, it affects the technical component.

- Professional and technical components
- Diagnostic test with a professional component (modifier 26, interpretation) and a technical component (modifier TC, equipment and staff); billing without a modifier is the global service.

78456 billing questions
How does 78456 differ from 78457?
78456 identifies acute venous thrombosis imaging. Use 78457 when the performed examination is the venous flow and pool imaging study described by that code.
When is 78458 a better fit?
78458 identifies bilateral venous thrombosis imaging. Select it when the bilateral study described by that code was performed, rather than choosing 78456 solely because thrombosis is suspected.
Can the professional and technical services be billed separately?
Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service. Without either modifier, the code represents the global service.
Does a multiple procedure reduction affect the entire service?
The cardiovascular diagnostic multiple procedure reduction applies to the technical component. It does not reduce the professional component under the CMS rule provided for this code.
What documentation supports reporting 78456?
Document the clinical indication for acute thrombus evaluation and the imaging examination performed. The record should distinguish this acute-thrombus study from venous flow and pool 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.
