			<html:p>Existing law requires a health facility, clinic, physician’s office, or office of a group practice that uses generative artificial intelligence to generate written or verbal patient communications pertaining to patient clinical information, as defined, to ensure that those communications include both (1) a disclaimer that indicates to the patient that a communication was generated by generative artificial intelligence, as specified, and (2) clear instructions describing how a patient may contact a human health care provider, employee, or other appropriate person.

			<html:p>This bill would require developers and deployers of artificial intelligence systems to make reasonable efforts to identify artificial intelligence systems used to support clinical decisionmaking or health care resource allocation that are known or have a reasonably foreseeable risk for biased impacts in the system’s outputs resulting from use of the system in health programs or activities.

The bill would require deployers to regularly monitor these artificial intelligence systems and take reasonable and proportionate steps to mitigate any bias that may occur. The bill would specify that a person, partnership, state or local governmental agency, or corporation may be both a developer and a deployer. The bill would specify that the department is not required to independently inspect, test, or evaluate the functionality of an artificial intelligence system. The bill would require, beginning January 1, 2027, developers to provide a report identifying compliance efforts with the above-described provisions to the department before making an artificial intelligence system commercially or publicly available to a deployer, as specified. The bill would require deployers, beginning January 1, 2027, to annually
			 provide the department with a report identifying their efforts to comply with identification, mitigation, and monitoring requirements established pursuant to these provisions. The bill would require the department to make these reports available on its internet website.</html:p>
