There are essentially two kinds of heath insurance: Fee-for-Service and Managed Care. Although these plans differ, they both cover an array of medical, surgical and hospital expenses. Most cover prescription drugs and some also offer dental coverage.

1. Fee-for-Service
These plans generally assume that the medical professional will be paid a fee for each service provided to the patient. Patients are seen by a doctor of their choice and the claim is filed by either the medical provider or the patient.

2. Managed Care
More than half of all Americans have some kind of managed-care plan. Various plans work differently and can include: health maintenance organizations (HM0s), preferred provider organizations (PPOs) and point-of-service (POS) plans. These plans provide comprehensive health services to their members and offer financial incentives to patients who use the providers in the plan.
