PPO and POS

 PPO allows the individual to use any service provider, whereas a POS requires the individual to use only pre-selected providers.

 POS allows the individual to use any service provider, whereas a PPO requires the individual to use only pre-selected providers

 POS uses a gatekeeper, while a PPO does not.

 PPO uses a gatekeeper, while a POS does not.

Correct

The main difference between a preferred provider organization and a point-of-service organization is that the POS uses a primary care physician (gatekeeper) to provide greater cost control. Both plans allow the individual to go outside the system, though the individual than pays a high portion of the costs.
