The bill adds diagnostic ultrasound tests to the statutory language that currently references diagnostic X‑ray tests and requires Medicare to make separate payments for portable ultrasound transportation and set up services. It also directs the Secretary of HHS to set supplier requirements for portable ultrasound services that are substantially similar to the existing federal standards for portable X‑ray suppliers (42 C.F.R. part 486, subpart C).
For providers and payers, the measure creates a new Medicare payment stream and a regulatory baseline for mobile ultrasound services. That changes the economics of delivering point‑of‑care and mobile imaging to nursing homes, homebound beneficiaries, and other sites outside fixed imaging centers, while raising questions about payment levels, coding, and compliance costs for suppliers.
At a Glance
What It Does
Amends 42 U.S.C. 1395x(s)(3) to add ultrasound to the list of diagnostic imaging tests and adds a new subsection to 42 U.S.C. 1395m requiring the Secretary to provide a separate Medicare payment for portable ultrasound transportation and set up services, implemented like the payment for portable X‑ray services.
Who It Affects
Medicare beneficiaries who receive mobile imaging (for example at home, in nursing facilities, or in community clinics), suppliers of portable ultrasound services and their staff, and CMS because it must specify payment and supplier requirements.
Why It Matters
It creates statutory footing for paying mobile ultrasound delivery separate from the imaging procedure itself, likely changing provider economics and access to bedside ultrasound—especially in underserved settings—while triggering CMS rulemaking to define supplier standards and payment amounts.

What This Bill Actually Does
The bill makes two targeted statutory changes. First, it edits the statutory definition that currently mentions “diagnostic X‑ray tests” and expands it to “diagnostic X‑ray and ultrasound tests.” That change is primarily lexical but signals congressional intent to treat ultrasound alongside X‑ray in the relevant Medicare provisions.
Second, the bill adds a new subsection to the Medicare payment statute directing the Secretary of Health and Human Services to establish a separate payment for portable ultrasound transportation and set up services. The language requires CMS to provide that separate payment “in the same manner and to the same extent” as the existing separate payment for portable X‑ray transportation and set up.
In practice, CMS will need to decide the payment mechanism, create or identify appropriate billing codes, and determine how that payment interacts with current Part B payments for the imaging procedure and professional interpretation.The statute also requires CMS to set supplier requirements for portable ultrasound services that are substantially similar to the supplier standards already applied to portable X‑ray suppliers under 42 C.F.R. part 486, subpart C. Those existing standards establish expectations about equipment condition, personnel qualifications, recordkeeping and quality control; applying similar rules to ultrasound will impose compliance obligations on suppliers delivering mobile ultrasound.Finally, the bill sets an effective date: the changes apply to services furnished on or after January 1, 2027.
That gives CMS a clear implementation window to develop payment rates, codes, and regulatory guidance before the start date.
The Five Things You Need to Know
The bill amends 42 U.S.C. 1395x(s)(3) to replace the phrase “diagnostic X‑ray tests” with “diagnostic X‑ray and ultrasound tests.”, It adds a new subsection to 42 U.S.C. 1395m requiring the Secretary to provide a separate Medicare payment for portable ultrasound transportation and set up services.
The separate payment must be provided “in the same manner and to the same extent” as the existing separate payment for portable X‑ray transportation and set up services.
The Secretary must specify supplier requirements for portable ultrasound services that are substantially similar to the portable X‑ray supplier rules found at 42 C.F.R. part 486, subpart C.
All amendments apply to services furnished on or after January 1, 2027, creating a fixed date for CMS implementation activity.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short title
Provides the Act’s name: the “Portable Ultrasound Reimbursement Equity Act of 2025.” This is purely stylistic but frames the bill’s purpose for regulators and stakeholders during implementation.
Add ultrasound to the statutory diagnostic imaging language (42 U.S.C. 1395x(s)(3))
Replaces the phrase “diagnostic X‑ray tests” with “diagnostic X‑ray and ultrasound tests.” That amendment enlarges the class of imaging modalities referenced in other Medicare provisions and removes any textual ambiguity about whether ultrasound falls under the same statutory umbrella as X‑ray for related payment or coverage rules.
Create separate Medicare payment for portable ultrasound transport and set up (42 U.S.C. 1395m new subsection (aa))
Directs the Secretary to provide a separate payment under Medicare for transporting and setting up portable ultrasound equipment, mirroring the existing separate payment framework for portable X‑ray services. The provision also obliges the Secretary to establish supplier requirements substantially similar to the federal portable X‑ray supplier standards (42 C.F.R. part 486, subpart C). Practically, this will force CMS to determine payment methodology, likely add or designate billing codes, and adopt or adapt supplier standards covering equipment, personnel, and quality control.
Effective date
Specifies that the statutory changes apply to services furnished on or after January 1, 2027. This deadline sets the timetable for CMS rulemaking and for suppliers to obtain any certifications, meet equipment standards, and update billing practices.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Homebound and nursing home Medicare beneficiaries — They gain clearer statutory access to bedside ultrasound when providers can bill separately for bringing and setting up equipment, which may increase availability of on‑site diagnostic imaging.
- Mobile diagnostic service suppliers and portable ultrasound vendors — Separate payment improves the revenue model for making onsite ultrasound visits, enabling investment in portable devices, staffing, and logistics.
- Hospitals and clinics that contract mobile imaging services — Facilities can avoid patient transports for basic ultrasound exams when mobile suppliers are financially feasible, reducing discharge/transfer burdens and potentially shortening time to diagnosis.
Who Bears the Cost
- CMS and the Medicare Trust Funds — New separate payments and likely increased utilization will increase program spending, requiring rate‑setting and budgetary adjustments.
- Small mobile providers and new entrants — Complying with supplier requirements modeled on 42 C.F.R. part 486 subpart C may impose accreditation, documentation, equipment maintenance, and personnel qualification costs.
- Fixed imaging centers and some outpatient facilities — Greater availability of mobile ultrasound could shift lower‑acuity imaging volume away from facility‑based sites, reducing ancillary revenue tied to facility utilization.
- CMS administrative units — CMS must establish payment rates, update claims processing systems, issue guidance, and enforce supplier standards, creating an unfunded operational workload.
Key Issues
The Core Tension
The central dilemma is access versus control: the bill aims to expand access to bedside ultrasound by creating a dedicated payment that makes mobile services financially viable, but doing so risks increased Medicare spending and potential quality gaps unless CMS carefully defines eligible services, sets prudent payment rates, and adapts supplier standards to the unique clinical realities of ultrasound.
The bill takes a narrow statutory approach—adding ultrasound to an existing phrase and ordering parity of separate payments with portable X‑ray—but leaves major implementation work to CMS. The statute does not specify how CMS should set the actual payment amount, whether it should mirror the exact dollar amount paid for portable X‑ray services, or whether payment should vary by geography, urgency, or complexity of the ultrasound exam.
That creates a risk that CMS will either underprice the transport/set up component (leaving providers economically disincentivized) or set a rate that materially increases Medicare spending if utilization rises.
Another unresolved area is scope: the bill refers to “portable ultrasound” without defining which types of ultrasound exams qualify (limited point‑of‑care scans, diagnostic obstetric studies, vascular duplexes, etc.). That ambiguity matters for payment, quality standards, and where responsibility for interpretation lies.
Requiring supplier standards substantially similar to portable X‑ray rules helps anchor quality expectations, but portable ultrasound poses distinct clinical and training issues—ultrasound image acquisition and interpretation are tightly coupled, and supplier standards focused on equipment and transport may not fully address clinician competency, documentation of findings, or how interpretations are billed under physician Part B services.
Finally, applying portable X‑ray supplier standards to ultrasound may create compliance friction. Some mobile ultrasound providers are clinician‑led (e.g., physicians using point‑of‑care ultrasound) rather than entities structured like traditional mobile imaging companies; imposing supplier rules designed for a different business model could raise barriers to entry or require regulatory tailoring that the statute does not mandate.
