The ACA attempted to expand the Medicaid program to cover all people living at 133% of the current poverty level, going into effect in 2014. The current level of poverty for a family of four is approximately a yearly income of $25,390. That would cover approximately 17 million people which is over 1/3 of the current uninsured population. Furthermore, physician office visit reimbursement will increase to level of Medicare for primary care physicians in 2014.
However, the Supreme Court ruled the Medicaid expansion unconstitutional. Since Medicaid is a federal-state partnership, the court ruled that states should have the option to expand Medicaid to 133% of their population, but should also have the option to keep their current Medicaid eligibility requirements and still receive federal funding. Some states are still planning to expand to 133%, but others are considering keeping their programs at their current levels.
