How Do HMOs Work?

How HMOs and HMO/POS Plans Work?

Health maintenance organizations (HMO) deliver health care to members using provider networks, which are the groups of doctors, hospitals and other health care providers that have agreed to serve members of a particular HMO. Health benefits are covered if the member uses providers that are in-network.

All New York HMOs also offer a point of service (POS) option that allows members to seek care from providers that are out-of-network. Services provided by out-of-network providers generally cost the member more in out-of-pocket expenses.

The table below highlights some of the important similarities and differences between HMOs and HMO/POS options.
