A health maintenance organization (HMO) and a preferred provider organization (PPO) have several differences such as which doctors patients can see, how much services cost, and how medical records are kept.The most significant difference between the two organizations is the option to select health care providers.n HMO requires that patients see only doctors or hospitals on their list of providers. With a PPO, patients can see any doctor they wish, usually within a preferred network of providers.
HMO and PPO plans develop from balancing financial and service options. The more expensive plans can vary in their features, i.e. a higher priced plan can mean more services are covered.
