Healthy Technology Act of 2021 This bill establishes that artificial intelligence (AI) or machine learning technology may be eligible to prescribe drugs. Currently, certain drugs may be dispensed only upon a prescription provided by a practitioner licensed by law to administer the drug. Under this bill, an AI or machine learning technology may qualify as such a prescribing practitioner if the technology is (1) authorized by state law to prescribe the drug involved; and (2) approved, cleared, or authorized under certain federal provisions pertaining to medical devices and products.
