What 78140 covers

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.

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.

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 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.
