Final answer:
The government-supported health insurance program that is not listed is PPO, while Medicaid, Medicare, and workers' compensation are government-supported.
Step-by-step explanation:
The government-supported health insurance program that is not included in the list provided is PPO (Preferred Provider Organization).
Medicaid and Medicare are both public health care programs funded and operated by the US government. Medicaid provides health insurance to individuals and families with low income. Medicare is designed to cover people over the age of 65, as older individuals have higher health care costs on average. Workers' compensation is another form of government-supported insurance, but it is specifically designed to provide coverage for employees who are injured or become ill as a direct result of their job. In contrast, a PPO is a type of health insurance often provided by private insurers rather than by the government.
