From the summary:
Newly enacted health reform legislation mandates dozens of health insurance changes. Many go into effect this year and next.
In March 2010, Congress enacted substantial health reform measures intended to increase access to affordable insurance, reduce the number of uninsured people, and reform both the health insurance market and the health care delivery system. The lion’s share of these reforms will take effect in 2014. However, some reforms go into effect well before that time.
This new policy brief from Health Affairs and the Robert Wood Johnson Foundation, the near-term effects of the Patient Protection and Affordable Care Act are examined and enumerated, providing context for key immediate reforms to the private health insurance market that will take effect in 2010 and 2011.
