Marla Tipping’s 14-year-old son Cam has to have his blood cleaned every two weeks. He has a rare condition that makes his body produce too much cholesterol.

Tipping says her family has had “to be absolutely vigilant in never having a lapse in coverage … because many carriers would never carry you with a preexisting condition again.”

Most of the speculation over the fate of the Affordable Care Act has focused on the individual mandate and what the decision could mean for the 2012 presidential election. However, if the Supreme Court decides to throw out large parts of the law along with the mandate, Tipping’s family is one of millions that could lose the benefit of provisions that are already in place.
