Insurance Terms

Billing and insurance can be confusing. This easy-to-understand list of health care terms may help you to better understand the typical types of insurance plans and common insurance and billing terms. Of course, you can always contact us for additional information.

Types of Insurance Plans

Today, most people are insured through one of three types of insurance programs: health maintenance organizations (HMOs), preferred provider organizations (PPOs) and point-of-service (POS).

Health Maintenance Organizations (HMO)

HMOs are one of the most common types of insurance. An HMO plan has a network of providers (physicians, hospitals and medical facilities) that plan members must use in order to have their medical treatment covered by insurance. HMO plans generally cost less but limit your choices. HMO plans typically require you to:

  • Pay no deductible
  • See a physician within the HMO network, usually after referral from your primary care physician
  • Pay for medical care outside the HMO network

Preferred Provider Organization (PPO)

A PPO plan offers tiered benefits with more choices. The typical PPO requires you to pay a deductible, but offers you a trade-off in terms of selecting your physician. You have the option to:

  • Reduce your out-of-pocket expense by choosing a preferred provider
  • Go outside the list of preferred providers and pay a higher out-of-pocket fee

Point-of-Service (POS)

A POS plan has elements of both the HMO and PPO. Your monthly premium is usually higher than a straight HMO, but you have the flexibility of receiving benefits both in and out of the network. A referral by a primary care physician is usually required to see a specialist. In most cases, a POS plan allows you to:

  • Choose within the POS network of physicians and hospitals and pay less
  • Receive complete or nearly complete coverage when your primary care physician refers you outside the network
  • Receive partial coverage when you refer yourself outside the network

Other Types of Insurance Plans
