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.
