About 78140: Red-cell sequestration study
A nuclear medicine study evaluates trapping or pooling of circulating red cells, typically when splenic sequestration is suspected.
Red-cell sequestration testing evaluates whether circulating erythrocytes are being trapped or pooled, usually in the spleen. Nuclear medicine staff prepare and administer labeled red cells and obtain study measurements; a physician with nuclear medicine expertise interprets the findings. The test may be used when hypersplenism or another disorder involving splenic removal of red cells is suspected. It evaluates red-cell handling rather than simply depicting splenic anatomy.
Report 78140 for the sequestration study performed and documented. The record should support the clinical question, the labeled-cell study and measurements, and the interpreting physician’s findings. CMS recognizes professional and technical components: report modifier 26 for interpretation, modifier TC for equipment and staff, or no component modifier for the global service when one billing entity furnishes both. The professional and technical components are separately priced in CMS data.

- 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.

78140 billing questions
How is this different from a red-cell survival study?
78140 evaluates red-cell trapping or pooling, usually in the spleen. A red-cell survival study, 78130, addresses how long red cells remain in circulation.
Which modifiers identify the professional and technical portions?
Use modifier 26 for the physician’s interpretation and modifier TC for the equipment and staff. Report the global service without a component modifier when one billing entity furnishes both.
What documentation supports reporting 78140?
Document the reason for evaluating sequestration, the labeled-cell study and measurements performed, and the physician’s interpretation of the findings.
Is this a red-cell mass measurement?
No. 78140 evaluates sequestration; 78120 measures red-cell mass. Select the code that matches the study performed and the diagnostic question documented.
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.
