CMS Proposes Permanent Virtual Supervision, Telehealth Rule for 2026

AB 460 heads to the Senate Health Committee today, aiming to modernize California’s rules for X-ray and CT contrast procedures with safe, virtual supervision — matching what’s already permitted for MRI. Tether Supervision supports this timely reform with one clarification around EMR access.

The ACR and RBMA are urging CMS to make virtual supervision permanent. Tether breaks down what’s at stake and why now is the time to act.

California’s AB 460 clears Assembly Appropriations, updating supervision rules for radiologic technologists by allowing real-time remote oversight. The reform aligns state law with federal standards and improves patient care access, particularly in rural communities.

CA AB 460, introduced in 2025, amends the Radiologic Technology Act to redefine direct supervision for radiologic technologists performing venipuncture, allowing real-time audio oversight with EMR access as an alternative to physical presence.

California’s CA AB-3097, introduced in 2024, aims to establish the Radiologist Assistant Practice Act, formalizing the RA role to boost healthcare efficiency and patient safety. Sponsored by ARRT, the bill sets registration and supervision standards, addressing radiology workforce shortages.

Expanding imaging hours beyond the traditional 9-to-5 schedule can significantly improve access for underserved populations, enhance patient satisfaction, and lead to better health outcomes. Learn how after-hours imaging benefits patients and imaging centers alike.

As CMS extends virtual direct supervision for diagnostic tests through December 31, 2025, radiology practices face critical questions about its permanence, application to IDTFs, and practical implementation. Explore expert insights on ensuring compliance and success.

Remote supervision of diagnostic imaging, started in 2020 by CMS, is gaining traction. Industry leaders like RBMA and ACR urge permanence, citing its safety, efficiency, and ability to address radiologist shortages while improving access, especially in rural areas.

CMS guidelines for contrast administration supervision ensure patient safety and compliance in radiology. From in-person mandates to virtual direct supervision extended through 2025, learn how Tether Supervision supports imaging centers with remote radiologist oversight.

Contrast media enhance CT and MRI scans but can cause side effects. CT contrast (iodinated) may lead to allergic reactions and kidney issues, while MRI contrast (gadolinium-based) might cause retention. Mild symptoms like nausea are common, but severe reactions are rare. Non-ionic CT contrast and macrocyclic MRI contrast are safer options.

Hospitals can now leverage remote supervision for contrast media administration through December 31, 2025, thanks to CMS’s extended virtual direct supervision rules. With a qualified radiologist overseeing via real-time audio-video technology and trained on-site staff ready to respond, this approach boosts efficiency while adhering to strict Medicare and ACR guidelines.

On August 17, 2023, the Alabama State Board of Medical Examiners issued a landmark ruling allowing ARRT-certified radiologic technologists to administer contrast media via IV injection under remote supervision of a board-certified radiologist. With real-time audio-visual technology and an on-site RN or equivalent professional, this decision reflects a shift towards telehealth-driven efficiency while prioritizing patient safety.
