Which of the following describes a key feature of a PPO?

A key feature of a Preferred Provider Organization (PPO) is the flexibility it offers in choosing health care providers. Members of a PPO have the option to see any doctor or specialist without needing a referral, which is a significant advantage over some other plans, such as Health Maintenance Organizations (HMOs) that require referrals for specialist services. This flexibility allows PPO members to receive care from both in-network and out-of-network providers, although using out-of-network providers typically results in higher out-of-pocket costs.

This characteristic is central to the appeal of PPOs, as it accommodates individuals who may want to see specific health care professionals or require more immediate access to specialists. The structure of a PPO is designed to give consumers more autonomy in managing their health care without the constraints often found in more managed plans.
