The main purpose of the Veterans Access to Direct Primary Care Act is to create a pilot program that allows veterans to access primary care services through health savings accounts. This initiative aims to give veterans more flexibility in choosing their healthcare providers outside of the Department of Veterans Affairs (VA) system. Key provisions of the Act include the establishment of a five-year pilot program where eligible veterans can receive funds in a health savings account. This account can be used to pay for primary care services provided by non-VA healthcare providers.
