The statement that best describes the difference between a health maintenance organization (HMO) and a preferred provider organization (PPO) is:
c. An HMO requires the insured individual to go to a provider within their organization while a PPO allows the insured individual the option to receive care from a non-preferred provider at a higher cost.
This statement accurately captures the fundamental operational difference between the two types of health insurance plans, where HMOs typically have strict networks of providers while PPOs offer more flexibility in choosing providers, albeit at a higher cost for out-of-network services.
