Health Maintenance Organizations

HMOs have long been known for a focus on prevention and wellness. Traditionally, HMOs required that you receive most of your care from one primary care physician who is aware of your total health picture. If you belong to an HMO, usually you must receive all of your medical care from network providers, except in emergencies. HMOs usually have flat copayments rather than deductibles and co-insurance and no lifetime limits on coverage.

After you enroll in an HMO, you typically will need to select a primary care physician who will be responsible for coordinating all of your care. Primary care physicians may be family practice doctors, internists, pediatricians, obstetricians-gynecologists, or general practitioners.

If you become ill, your primary care doctor will see you first, unless it is an emergency. Your primary care doctor will give you a referral if he or she thinks you need to see a specialist. Usually, your HMO will not provide coverage for a specialist unless you have this referral.
