PA HB2173

Establishes mandatory state licensure for medical imaging professionals, radiation therapists, and radiologist assistants beginning two years after enactment, requiring certification from a board-approved medical imaging certification organization, completion of approved educational programs, and passage of applicable examinations

Creates five licensed medical imaging modalities: diagnostic medical sonography, limited x-ray machine operations, magnetic resonance imaging, nuclear medicine technology, and radiography, with professionals limited to practicing only within modalities for which they are certified

Requires radiologist assistants to work under written clinical protocols signed by a supervising radiologist, allows them to perform advanced procedures including fluoroscopy, injections, and invasive procedures, but prohibits them from interpreting images, diagnosing, or prescribing medications

Mandates $1,000,000 minimum professional liability insurance coverage per occurrence for all licensees under this section, with biennial license renewal requiring continuing education and current certification

Provides exemptions from licensure requirements for licensed practitioners whose scope already includes imaging, physician assistants and nurse practitioners performing fluoroscopy under supervision, auxiliary personnel under chiropractors/dentists/podiatrists, students in approved programs, and federal government employees performing official duties
