Final answer:
The statement is FALSE. In an HMO, primary care physicians are not charged for the cost of specialist's services when they refer patients.
Step-by-step explanation:
The statement is false. In an HMO, primary care physicians are responsible for referring patients to specialists when necessary, but they are not typically charged for the cost of the specialist's services. Instead, HMOs often have a predetermined network of specialists that they work with and reimburse directly. This system is in place to ensure that patients receive appropriate care while also controlling costs and promoting efficiency within the healthcare system.
