119th CONGRESS
2d Session
S. 4624
IN THE SENATE OF THE UNITED STATES
May 21, 2026
Mr. Boozman (for himself and Mr. Luján) introduced the following bill; which was read twice and referred to the Committee on Finance
A BILL
To amend title XVIII of the Social Security Act to provide for payment for services of radiologist assistants under the Medicare program, and for other purposes.
Short title
This Act may be cited as the Medicare Access to Radiology Care Act of 2026
.
Findings
Congress makes the following findings:
Radiologist assistants are advanced-level radiographers who are critically important members of the radiologist-led team.
Radiologist assistants work strictly under the supervision of a radiologist to promote high standards of patient care by assisting radiologists in the diagnostic and interventional imaging environment.
In every jurisdiction authorizing radiologist assistants to practice, they are only permitted to furnish services when delegated by and under the supervision of a radiologist.
Radiologist assistants value their working and professional relationships with radiologists and have never sought, nor do they seek, the ability to practice independent of radiologists.
While radiologist assistants perform various valuable professional services and may make and communicate initial observations to the radiologist, radiologist assistants are not qualified to perform interpretations (preliminary, final, or otherwise) of any radiological examination.
Removing barriers to care rendered by radiologist assistants under the supervision of a radiologist will provide value-based, efficient solutions to improve patient outcomes while ensuring patient safety.
