In February 2018, Stephen Swett went to the emergency room at Westchester Medical Center in New York seeking help for withdrawal from Suboxone, which treats opioid addiction. Swett — a 44-year old truck driver — says he sat on a gurney until he was discharged. Then in June of last year, the hospital filed a court summons, the beginning of its attempt to collect the $2,539.43 it said Swett owed for his trip.
