A person eligible for Medicaid in one state is:

The correct choice is that a person eligible for Medicaid in one state is not necessarily eligible in all other states. This is because Medicaid is a state-federal program, and each state has its own specific eligibility requirements, benefits, and rules. While federal guidelines provide a framework for Medicaid, the interpretation and implementation of these guidelines can vary significantly from one state to another.

For instance, if an individual qualifies for Medicaid in their home state due to specific income and resource limits, these standards may differ in another state. Therefore, when someone moves from one state to another, they must apply for Medicaid in the new state, and their eligibility will be determined based on that state's criteria. This can result in a situation where someone loses their benefits simply by relocating, reflecting the unique nature of state-administered programs.

The other choices suggest broader eligibility across state lines than what is legally allowed. Medicaid is designed to serve state residents, so the assertion that someone is eligible in adjacent states or any state across the country does not hold true as each state controls its program. While some people may maintain coverage if they are temporarily out of state, full eligibility is not guaranteed when moving between states.
