Your insurance is required by federal law to notify both the patient and doctor of decisions they make on your claims. This notification usually arrives by mail and is named differently by each insurance company. Some examples are Remittance Advice, Explanation of Benefits (EOB), or Explanation of Services.
It is important to read these notifications because often they tell patients in advance how much was assigned to patient responsibility by their insurance. It also helps to eliminate clerical errors as the patient is aware of what services they received.
