Final answer:
The incorrect statement related to immunization benefits is that coverage for children's vaccinations is optional for parents. Instead, health benefit plans typically have to cover required immunizations, although there may be age restrictions and state-by-state variations in coverage.
Step-by-step explanation:
The false statement regarding required immunization benefits for each child listed as a dependent on a health benefit plan is that coverage is optional for parents. In reality, health benefit plans often must cover required immunizations for dependents, but there might be age restrictions, and coverage details can be influenced by state law. Moreover, while the plan must cover immunizations, parents are still typically expected to ensure their children receive these immunizations. Age restrictions can apply, and state laws indeed might influence the type and extent of coverage available on a health benefit plan.
