FILE - This Feb. 2, 2015, file photo, depicts a part of a U.S. $100 bill. A government report says the nationÂs health care tab grew at the fastest rate in eight years in 2015, driven by the coverage expansion in President Barack ObamaÂs law and by costly prescription drugs. The $3.2 trillion averages out to $9,900 per person, although most of that is spent caring for the sickest patients.
