Radiology Outpatient Ordering Transmission (ROOT) Act

The ROOT Act (S 1692) requires doctors ordering outpatient imaging tests (like X-rays and MRIs) to use a tool that verifies test appropriateness starting January 1, 2026, with exceptions for preventive screenings (e.g., mammograms, lung cancer screenings), clinical trials, and small/rural practices. The tool must transmit data to Medicare, including the ordering doctor’s ID and test details, to track compliance. Medicare will identify doctors with low compliance rates (using the tool infrequently) and study how this affects imaging use, reporting findings to Congress every five years beginning in 2031.
