Washington HB 2113 for Virtual Contrast Supervision: 2026 Requirements & Changes Explained

Key Takeaways

• Washington HB 2113 officially allows physicians to supervise intravenous contrast administration via real-time audiovisual technology, modernizing a supervision framework that previously required in-person presence.
• Audio-only communication does not meet the new standard; live, two-way video is explicitly required under the bill's statutory language.
• On-site safety requirements remain unchanged: qualified staff capable of recognizing and responding to adverse contrast reactions must still be physically present at the imaging facility.
• Imaging facilities must audit their supervision setup, confirm that audiovisual technology meets HB 2113's real-time video standard, and update internal protocols to ensure total compliance. 
• At ContrastConnect, we help imaging facilities navigate Washington HB 2113's 2026 virtual supervision requirements. Our purpose-built, CMS-compliant virtual supervision platform connects a dedicated supervising physician to your facility via live audio and video within seconds and automatically generates audit-ready documentation for every session. 

Washington Just Changed How Contrast Supervision Works

Washington HB 2113 officially authorizes physicians to supervise intravenous contrast administration through real-time audiovisual technology, ending years of statutory ambiguity that left imaging facilities operating without a clear legal footing.

Before this bill, Washington's statutory language recognized physician supervision but did not formally define virtual presence as a qualifying method. Facilities using remote oversight arrangements were operating in interpretive territory and were exposed to compliance risk during audits and accreditation reviews. HB 2113 closes that gap by establishing virtual direct supervision as a legally recognized and clearly defined modality under Washington state law.

The implications extend well beyond Washington. As states across the country face radiologist shortages, geographic access limitations, and an expanding telehealth infrastructure, HB 2113 reflects a broader national shift in how direct supervision is defined and enforced in diagnostic imaging.

What Counts as Virtual Direct Supervision Under HB 2113

Not every remote communication setup qualifies. HB 2113 is specific about what technology and availability standards must be met for virtual supervision to be considered compliant under Washington law.

Real-Time Audio & Video Is Required

The bill requires that supervision occur through live, interactive audio and video communication. This means the supervising physician must be able to see and hear what is happening at the imaging facility in real time, and must be reachable and visually present during the procedure.

A recorded video, a delayed connection, or a system with significant latency does not meet this threshold. The interaction must be contemporaneous with the contrast administration.

Audio-Only Communication Does Not Qualify

This is one of the most operationally significant details in the bill. A phone call, even a live one with an immediately available physician, does not satisfy the supervision requirement under HB 2113. 

The visual component is not optional. Facilities relying on telephone-based physician oversight for contrast studies need to upgrade their communication infrastructure before the law takes effect or risk falling out of compliance.

Immediate Availability Is Still Mandatory

Virtual presence doesn't mean passive availability. The supervising physician must be immediately available via the audiovisual connection, not simply reachable within a reasonable timeframe. 

This mirrors the previous federal CMS framework for direct supervision, which requires the physician to be present in the office suite and immediately available to furnish assistance and direction throughout the procedure. HB 2113 applies that same standard of immediacy to the virtual context, meaning the physician cannot be simultaneously occupied in a way that prevents real-time responsiveness.

Safety Requirements That Did Not Change

On-Site Staff Must Be Trained for Contrast Reactions

The on-site personnel requirement under HB 2113 is non-negotiable. At least one qualified staff member must be physically present at the facility during every contrast-enhanced study.

Staff responsible for on-site response should be competent in identifying the full spectrum of contrast reactions, from mild symptoms such as nausea and urticaria to severe anaphylactic reactions requiring immediate intervention. 

Facilities should ensure their training documentation is current, role-specific, and aligned with the ACR Manual on Contrast Media, which outlines both recognition criteria and graded response protocols.

This on-site requirement also functions as the structural counterweight to virtual supervision. The physician provides remote oversight and clinical decision-making; the on-site staff member handles immediate physical response. Both roles are essential, and neither substitutes for the other. 

Escalation Protocols Still Apply

When an adverse contrast reaction occurs, the facility's escalation pathway must be clearly defined and immediately executable. HB 2113 does not modify these obligations. The supervising physician, even when present virtually, must be integrated into the escalation chain. 

Facilities should review their contrast reaction emergency plans to confirm that the virtual supervision model is explicitly accounted for, including communication steps, documentation requirements, and criteria for activating emergency medical services.

What This Means for Imaging Centers in Washington

For imaging centers operating in Washington, HB 2113 is both a permission structure and a compliance obligation. Centers that have been using informal or loosely defined virtual oversight arrangements now have a statutory framework to work within, and a clear set of requirements to meet.

Greater Staffing Flexibility Without Reducing Oversight

One of the most immediate practical benefits of HB 2113 is the staffing flexibility it creates. Imaging centers, particularly those in rural Washington or multi-site operations, no longer need a physician to be physically present at each location for every contrast study. 

A single supervising physician can provide compliant oversight across multiple facilities simultaneously, provided the audiovisual infrastructure and on-site staffing requirements are met at each location. This reduces operational cost without compromising the supervision standard.

Clear Legal Authority for Virtual Supervision Models

Before HB 2113, facilities using virtual supervision arrangements were operating in interpretive territory. The existing statute didn't prohibit virtual supervision, but it didn't explicitly authorize it either. That ambiguity created compliance risk, particularly for facilities subject to audit or accreditation review. HB 2113 eliminates that uncertainty by establishing virtual direct supervision as a formally recognized and legally defined modality under Washington state law.

What Imaging Facilities Should Do to Remain Compliant

1. Audit Current Supervision Arrangements

Start by mapping exactly how physician supervision is currently structured at your facility. Identify whether supervision is in-person, virtual, or hybrid, and document the specific technology, personnel, and protocols involved. 

Compare that current state against the explicit requirements of HB 2113. Any gaps between your existing model and the statutory standard should be treated as compliance action items, not operational preferences.

2. Confirm Your Audiovisual Technology Meets Statutory Requirements

The technology requirement in HB 2113 is not satisfied by general-purpose video conferencing tools used informally. The audiovisual connection must support real-time, two-way interaction with sufficient reliability to ensure the supervising physician is genuinely and immediately available throughout the procedure. 

Consumer-grade platforms with inconsistent connectivity, latency issues, or limited clinical workflow integration may not meet this standard in practice, even if they technically transmit live video.

Facilities should conduct a formal technology assessment that evaluates the following before the effective date:

• Connection reliability and uptime guarantees from your platform provider.
• Latency levels during peak usage periods at your specific facility locations.
• Whether the platform supports simultaneous multi-site supervision without degraded performance.
• Documentation and audit trail capabilities for supervision session records.
• HIPAA compliance and data security certifications for the audiovisual platform in use.
• Ability to integrate with existing RIS/PACS workflows without disrupting technologist efficiency.

If your current technology doesn't hold up under that assessment, now is the time to identify and implement an alternative. Purpose-built virtual supervision platforms like ContrastConnect are designed specifically for this clinical and regulatory context, with the reliability, compliance documentation, and workflow integration that general-purpose video tools simply weren't built to provide.

3. Verify On-Site Staff Training for Adverse Event Response

On-site staff training is an ongoing operational responsibility. Before HB 2113 takes effect, every imaging facility in Washington should conduct a formal review of training records for all personnel who will be present during contrast-enhanced studies.

That review should confirm that each staff member has documented current competency in recognizing contrast reactions and in emergency response. If gaps exist, they need to be addressed through structured training programs, not informal refreshers.

4. Update Internal Protocols to Reflect the New Legal Framework

Your facility's written supervision policies must explicitly reflect HB 2113's requirements. That means updating contrast administration protocols, physician supervision agreements, and emergency response documentation to reference the new statutory standard. Policies that describe supervision in vague terms should be revised to define the virtual supervision arrangement in specific, operational language that matches the bill's requirements.

Frequently Asked Questions

Does HB 2113 eliminate the requirement for physician supervision during contrast administration?

No. HB 2113 does not eliminate physician supervision; rather, it expands the permissible delivery method. A licensed physician, Advanced Registered Nurse Practitioner (ARNP), or physician assistant must still supervise every IV contrast administration, with physician supervision now permissible via real-time, two-way audiovisual technology under the new virtual pathway.

What technology is required to meet the virtual supervision standard under HB 2113?

HB 2113 requires real-time, interactive audio and video communication. The connection must be live and two-way, allowing the supervising physician to see and hear the clinical environment during the procedure and remain immediately available to provide guidance or intervention. Audio-only communication does not satisfy this requirement. Facilities should use platforms with documented reliability, HIPAA compliance, and clinical-grade performance, not general-purpose consumer video tools.

Does HB 2113 apply to all imaging facilities in Washington or only certain facility types?

HB 2113 applies to imaging facilities operating under Washington's radiologic technology supervision statutes that administer IV contrast — broadly, any setting where technologists credentialed under Chapter 18.84 RCW perform parenteral contrast procedures under physician supervision.

How does HB 2113 interact with existing CMS supervision requirements for imaging centers?

HB 2113 operates in parallel with federal CMS supervision requirements, which already recognize virtual direct supervision in certain contexts for Medicare-participating facilities. Outpatient imaging centers billing under the Medicare Physician Fee Schedule or the Hospital Outpatient Prospective Payment System must satisfy both the state law requirements under HB 2113 and applicable CMS supervision standards.

How many locations can ContrastConnect supervise at once?

As many as you need. At ContrastConnect, we offer scalable, multi-site virtual contrast supervision. Unlike general-purpose video tools repurposed for clinical oversight, our infrastructure is built to support simultaneous supervision across multiple imaging locations without degraded connection quality or compromised physician availability.
