Back in March, President Obama signed into law the Patient Protection and Affordable Health Care Act. In this ongoing series, we’ll discuss the new law and try to help you make sense of it. So what has changed in the last five months?

The new law implements a number of reforms in the health care industry over the next four years. Here are the major changes since March:

- The government debuted a new website: www.healthcare.gov. It is supposed to serve as a central command, where consumers can see their insurance options and compare pricing, and get news on the new law. A lot of that information isn’t there yet, so stay tuned until October. A bigger, better version of the website is supposed to roll out then.

- A new program, the Preexisting Condition Insurance Plan, was deployed. Right now, insurance companies can deny you coverage if you have previously been sick or injured. The new program will cover people who have been uninsured for these reasons. It is intended to serve as a transition to 2014, at which point insurance companies will be prohibited from refusing coverage to people with preexisting conditions. Learn more about how this affects you.

- Starting September 23, young adults will be allowed until age 26 to stay on the health insurance of a parent. This is true as long as the parent’s plan covers dependents and the child isn’t eligible for his or her own job-based coverage. Learn more about how this affects you.
