HB 1546 Washington House · 2025-2026 Regular Session

Concerning general supervision of diagnostic radiologic technologists, therapeutic radiologic technologists, and magnetic resonance imaging technologists by licensed physicians.

House Bill 1546 changes the supervision rules for diagnostic, therapeutic, and magnetic resonance imaging technologists in Washington State. It allows these technologists to perform intravenous contrast procedures under "general supervision" by a licensed physician, rather than requiring "direct supervision." Under general supervision, the physician does not need to be physically present, but a qualified healthcare provider trained to manage adverse events must be on-site at the facility. The bill also permits remote general supervision using real-time audio and visual telecommunications, provided all relevant laws and policies are followed and the physician remains available.
