About 78103: Bone marrow imaging, multiple views
Reports nuclear medicine imaging of bone marrow using multiple views to assess marrow distribution or abnormal marrow activity.
This service uses radiopharmaceutical imaging to show the distribution and activity of bone marrow across multiple views. It is performed in a nuclear medicine setting, with imaging acquired by technologists and interpreted by a qualified physician, commonly a nuclear medicine physician. The clinical question may involve abnormal marrow distribution or activity; the documented study extent distinguishes this service from limited-area and whole-body marrow imaging.
Select the code based on the study performed and its documented extent: limited-area imaging is reported with 78102, while whole-body imaging is reported with 78104. The record should support the marrow-imaging indication, views or anatomic coverage obtained, and the physician’s interpretation. Report the global service without a component modifier, or report the interpretation with modifier 26 and the equipment-and-staff portion with modifier TC.
