Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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 in CMS data.
