This is the tragic story of a girl named Nataline Sarkisyan who was denied a liver transplant and allowed to die, even though her insurance company CIGNA had committed to the precedure prior to her developing a lung infection. As a result, the family has now hired Mark Geragos to sue CIGNA for having "maliciously killed her."
If this moves you - and I have no doubt that it does unless you're inhuman or a Turk - then watch the movie Sicko. Nataline's life is just one example of the exploitation of patients by ruthless insurance companies for profit.
It doesn't have to be this way.
