As part of the 2024 Medicare Physician Fee Schedule final rule, the Centers for Medicare & Medicaid Services (CMS) has extended its allowance for virtual direct supervision of diagnostic procedures — including contrast-enhanced imaging — through December 31, 2025. This ruling allows supervising physicians to continue overseeing imaging procedures remotely, via real-time audio/video technology, rather than being physically present during the exam.

The change, originally introduced during the COVID-19 public health emergency, was designed to provide greater flexibility to healthcare providers. With this extension, CMS aims to continue improving access in rural or understaffed locations while maintaining safety protocols. According to CMS, this flexibility can be used “without compromising the quality or safety of care when proper protocols are in place” (source).

What Does Virtual Supervision Mean for Imaging?

For diagnostic imaging studies involving contrast — such as CT with iodinated contrast or MRI with gadolinium — CMS requires direct supervision. Under this temporary policy extension, “direct” means the supervising physician must be immediately available via real-time audio/video, not necessarily physically present.

This is a major shift from pre-pandemic policies, which required on-site supervision. In practical terms, this allows radiologists or other supervising physicians to remain at a central or remote location while technologists administer contrast, as long as they can respond instantly if needed.

Teleradiology and Rural Hospitals Stand to Benefit

One of the most impacted beneficiaries of this rule is the teleradiology sector, along with rural hospitals and outpatient imaging centers.

Hospitals without full-time radiologists on-site can now safely administer contrast-enhanced studies without needing to delay or cancel appointments due to a lack of available in-person supervision. According to a report from the Radiology Business Management Association (RBMA), this flexibility is not only helping providers maintain operations, but it’s also helping prevent service interruptions in areas with chronic staffing shortages (source).

By enabling radiologists to supervise multiple sites virtually, healthcare systems gain efficiency without compromising safety or quality. This is especially important as radiology continues to face a projected workforce shortfall of over 20,000 radiologists by 2034, according to the AAMC.

Compliance Still Matters

Though the rule allows remote supervision, the responsibility remains high. Providers must ensure that:

• A two-way real-time communication system is in place (e.g., secure video or telehealth platforms)
• Supervising physicians are credentialed, available, and familiar with the facility’s protocols
• Documentation clearly identifies who provided supervision and how

The American College of Radiology (ACR) cautions that facilities using virtual supervision must maintain complete compliance records and be ready to demonstrate their supervision protocols during audits (source).

Long-Term Outlook: Will It Become Permanent?

While this extension is only valid through the end of 2025, many in the radiology community hope it will lead to a permanent rule change. The pandemic accelerated the adoption of remote workflows and proved that many diagnostic services can be safely and efficiently supervised remotely.

Organizations like RBMA and ACR are actively advocating for CMS to consider making virtual supervision a lasting policy, especially given the geographic gaps in radiology coverage and the increasing demand for contrast-enhanced imaging services.

Conclusion

CMS’s decision to extend virtual supervision through 2025 reflects a shifting healthcare landscape that values flexibility, access, and efficiency. For imaging departments, this offers an opportunity to streamline workflows, improve scheduling, and extend radiologist coverage across multiple sites — all without compromising patient safety.

As the radiology community continues to push for broader policy modernization, facilities that adapt now will be better positioned to thrive in the hybrid care models of the future.
