There is a separate bill for the physician who treated you in the emergency room. This is one of the easily hidden bills that most people are unaware of. The billing company for the physician is usually different from the company handling the emergency room. You would think that by giving the emergency room your health insurance details they would forward that information to the physicians. Unfortunately, they do not, often leaving this bill unpaid due to ignorance. The hospital billing department should direct you on how to obtain this bill.
