knee injury

A college student's bill for outpatient knee surgery is a whopper — $96K — but the most mysterious part is a $1,167 charge from a health care provider she didn't even know was in the operating room.

After a sports injury, Esteban Serrano owed $829.41 for a knee brace purchased with insurance through his doctor's office. The same kind of brace costs less than $250 online.
