What 78185 covers
This code covers a nuclear medicine examination that produces images of splenic tissue and its distribution. It may be used when a clinician needs to assess splenic tissue, including in a workup for suspected accessory or ectopic spleen. A nuclear medicine technologist typically performs the imaging in a hospital department or imaging facility, and a qualified physician interprets the study.
Select the code when the documented service is spleen imaging, rather than a blood-volume, cell-survival, or sequestration study. The imaging record should support the spleen study performed, and the physician report should document the interpretation. CMS allows the service to be billed globally, with both components, or as the professional component using modifier 26 or the technical component using modifier TC. Use the component claim that reflects the work furnished by the billing entity.
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.

78185 billing questions
How is 78185 different from a red cell sequestration study?
78185 reports imaging of splenic tissue. Code 78140 describes a red cell sequestration study, which evaluates red-cell handling rather than reporting spleen images.
Can the professional and technical portions be billed separately?
Yes. Report modifier 26 for the physician's interpretation or TC for the equipment and staff portion. A claim without either modifier represents the global service.
When should a combined liver-and-spleen imaging code be considered?
Use a combined liver-and-spleen imaging code when the documented examination images both organs. Code 78185 is for the spleen imaging service.
What documentation supports reporting 78185?
The record should identify the spleen imaging performed, and the interpreting physician's report should document the findings. Technical-component documentation should support the imaging acquisition.
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.
