"Per the reconciliation instructions in the budget resolution for FY2017 (S.Con.Res. 3), the House passed its reconciliation bill, H.R. 1628--the American Health Care Act (AHCA)--with amendments on May 4, 2017. The House bill was received in the Senate on June 7, 2017, and the next day the Senate majority leader had it placed on the calendar, making it available for floor consideration. The Senate Budget Committee published on its website a 'discussion draft' titled, 'The Better Care Reconciliation Act of 2017' (BCRA) on June 22, 2017, and subsequently updated the discussion draft on June 26, July 13, and July 20. The Senate's draft legislation is written in the form of an amendment in the nature of a substitute, meaning that it is intended to be considered by the Senate as an amendment to H.R. 1628, as passed by the House, and that all of the House-passed language would be stricken and the language of the BCRA would be inserted in its place."
