I tried reading it but a lot of it is amendments to a dozen other laws so you'd have to do a lot of cross-checking to understand what is being changed.
Early on, there is a lot in it that discusses changes to SS and Medicare, although I'm not sure I understand why. Maybe PPACA also impacted those programs?
Starting at page 45, it repeals the cost-sharing subsidy of the PPACA (section 1402). This was the part of Obamacare that would help you pay for coverage if you were under a certain income amount.
It appears to be replaced by a new thing called the "Patient and State Stability Fund" where the federal government provides funds to each state + DC to administer their own type of PPACA. Each state must file an application to receive them.
The amounts provided to each state are as follows:
2018: $15 billion 2019: $15 billion 2020 through 2026: $10 billion
The next part I get lost on. "Sec. 133 Continuous Health Insurance Coverage Incentive". It describes a policy where penalties are imposed on individual or small group market policy holders, but I think they omitted a "not" after "shall" (line 10 of sec 2711).
The next bits appear to be repeals?
