On May 4, 2017, Faso voted in favor of the American Health Care Act, the House Republican bill to repeal the Patient Protection and Affordable Care Act (Obamacare). He faced protests in his congressional district over his position on the AHCA. During his 2018 re-election campaign, Faso said that he supported protections for individuals with preexisting conditions. Faso said that the AHCA bill that he voted for would have protected people with preexisting conditions; however "The New York Times" noted that the bill would have allowed states to drop protections for individuals with preexisting conditions.
