AB 511 California Assembly · 2025-2026 Regular Session

Radiologist assistants.

Summary
Existing law, the Radiologic Technology Act, prohibits a person from administering or using diagnostic or therapeutic X-rays on human beings in this state, unless that person either qualifies for a specified exemption or has been certified or granted a permit by the State Department of Public Health, as specified, is acting within the scope of that certification or permit, and is acting under the supervision of a healing arts licensee. A person who violates a provision of the Radiologic Technology Act or regulation of the department adopted pursuant to that act is guilty of a misdemeanor. This bill would prohibit a person from holding themselves out as a radiologist assistant unless the person meets certain requirements, including that they have passed the radiologist assistant examination, as specified, and that they maintain current registration with prescribed entities. The bill would require a radiologist assistant to work only under the supervision of a radiologist and would prohibit a radiologist assistant from functioning in that capacity independent of a supervising radiologist. The bill, among other things, would authorize a radiologist assistant to communicate and document initial clinical and imaging observations or procedures only to a radiologist for the radiologist's use. The bill would authorize a supervising radiologist to delegate to a radiologist assistant, as the radiologist determines appropriate to the assistant's competence, those tasks or services that a radiologist usually performs and is qualified to perform. The bill would provide that a violation of its provisions does not constitute a misdemeanor.

What changed between versions

02/10/25 - Introduced AB511 · 1 edit
MINOR
No substantive policy changes were made to AB 511 between these two versions. The differences are entirely formatting and presentation: the original introduced bill's line numbers, page headers, and layout were replaced with a web-based display format including navigation menus, search tools, and metadata fields. The actual legislative text (Section 1 findings and new Section 114876 of the Health and Safety Code) is identical in both versions.
TECHNICAL

The bill was reformatted from a traditional introduced-bill layout (with line numbers, page headers like '99' and 'AB 511', and column formatting) into a web-based display format with navigation elements, quick search fields, version tracking links, and a digest key section.
