About 78111: Multiple-sample plasma volume study
Nuclear medicine measurement of circulating plasma volume using multiple blood samples, reported when serial sampling is used to assess a suspected blood-volume abnormality.
This study measures circulating plasma volume through tracer administration followed by collection and analysis of multiple blood samples. It may be used when a clinician needs to assess plasma-volume expansion or depletion, including in the evaluation of an apparent red-cell concentration abnormality. Nuclear medicine staff typically perform the technical work in a hospital setting, while a qualified physician interprets the study and reports the findings.
Choose this code when the plasma-volume study uses multiple samples; the single-sampling service is a different code. Documentation should identify the clinical reason for the study, the sampling approach, and the interpretation. Medicare recognizes separate professional and technical components: report modifier 26 for the interpretation, modifier TC for the equipment and staff, or neither modifier for the global service. The 2024 Medicare file records facility services for this code and no office services.

78111 billing questions
How does this differ from the single-sampling plasma-volume code?
Report 78111 when the study uses multiple blood samples. Use 78110 when the plasma-volume determination uses a single sample.
Which modifier identifies the physician interpretation?
Use modifier 26 for the professional component, which represents interpretation. Modifier TC identifies the technical component.
Can the technical and professional components be billed separately?
Yes. The physician or other billing entity may report the applicable component with modifier 26 or TC; billing without either modifier represents the global service.
What documentation supports reporting the multiple-sample service?
The record should support the clinical reason for measuring plasma volume, document that multiple samples were used, and include the interpretation when the professional component is billed.
How does this differ from a whole blood volume determination?
78111 measures plasma volume using multiple samples. 78122 is used when the requested study determines whole blood volume rather than plasma volume alone.
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.
