Final answer:
A PPO's goal is to channel patients to providers that discount services. Copayment fees are involved. A staff model is not the most common type of PPO and claim forms are typically completed by providers.
Step-by-step explanation:
A Preferred Provider Organization (PPO) is a type of health insurance plan that contracts with medical providers to offer discounted rates to insured individuals. One of the true statements about a PPO is that its goal is to channel patients to providers that discount services, which is option 1). A PPO typically involves copayment fees, so option 2) is false. Option 3) is incorrect because a staff model is a common type of HMO, not a PPO. Lastly, claim forms are typically completed by providers, not members, so option 4) is also false.
