The VA Mission Act of 2018 was signed into law to improve veteran access to healthcare. It addresses issues like in-network and non-VA care, veterans' homes, walk-in VA care, and prescription drugs. The Act contains five titles that focus on expanding care options, improving VA facilities, increasing healthcare professionals, addressing underserved areas, and other administrative details. It aims to remove limitations that previously forced veterans to wait for VA appointments or travel long distances to receive care.
