The "Medical Professional Access Act" aims to enhance the flexibility and responsiveness of health care professionals during national crises by establishing license portability. It amends title 41 of the United States Code, allowing medical personnel to practice across state lines without needing additional local licensure when responding to specific emergencies under a Federal Government contract. This provision overrides state licensure requirements, enabling faster deployment of essential medical services across any state, the District of Columbia, or U.S. territory. This expanded portability is specifically for services rendered in response to a federally declared emergency and must be within the scope of their authorized duties under that contract. The legislation provides a comprehensive definition for a "federally declared emergency," encompassing declarations by the President under the Stafford Act, public health emergencies declared by the Secretary of Health and Human Services, and other national crises certified by an Executive Department head and published in the Federal Register.
