Medical bills or itemized statements are associated with care rendered to an individual by a physician, hospital or group practice for a specific illness or condition. These amounts relate to hospital admissions, office visits, therapy or surgeries. Additional costs may be incurred for rehabilitation, injections, prescription medication or orthopedic appliances. In personal injury or workers' compensation matters, medical expenses are tied to an actual event, e.g., motor vehicle accident, slip and fall or injury in the course of employment. In addition to proving damages, medical bills contain an abundance of other valuable information which may be particularly helpful to the legal team in the litigation of a case.
