Changing the legal title for physician assistants to physician associates.

This bill changes the official title of "physician assistants" to "physician associates" in Washington state law, administrative rules, and billing systems. It requires state agencies, health plans, and healthcare facilities to update all contracts, materials, and regulations to use the new term, while allowing both titles to be used interchangeably during a transition period. The change aligns with national professional standards and aims to better reflect the education, training, and collaborative role of these healthcare providers. The bill amends multiple sections of state law to implement this terminology shift across licensing, billing, and healthcare operations.
