What 76377 covers
A radiologist or other qualified interpreting professional uses an independent workstation to create and interpret three-dimensional views from an existing CT, MRI, ultrasound, or other tomographic study. The reconstruction can clarify anatomy or show spatial relationships that are difficult to assess on the source images alone, such as vessels, bones, or a complex lesion. The service includes the interpretation and a report of the rendered images; it is distinct from simply reviewing the original image series.
Select this code when the documented 3D postprocessing requires an independent workstation and the rendering is interpreted and reported. The record should support the medical purpose of the reconstruction and identify the resulting findings. CMS recognizes professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies the equipment and staff, and reporting the code without either modifier represents the global service.
