Ouch! I'm a Retired Grocery-Store Owner from Brooklyn Who Fell

Ouch! I'm a retired grocery-store owner from Brooklyn who fell out of a tree while bird watching in upstate New York. The bill from the hospital for putting a cast on my broken arm is estimated to be $5,000. How was this price for medical care determined?

A) by the intersection of supply and demand
B) by the intersection of supply and demand, but the government played a significant role in increasing supply and imposing a payment limit through the Medicaid program
C) by the intersection of supply and demand, but the government played a significant role in reducing supply and imposing a payment limit through the Medicare program
D) by the involvement of the government through the Medicare program, and the cost was increased because hospitals are not required to deliver emergency-room care to the uninsured
E) by the intersection of supply and demand, but the government played a rather insignificant role despite providing Medicare health insurance
