Final answer:
Health policy advertisements must clearly indicate if they only cover a specific illness to prevent consumer misunderstanding. These disclaimers provide essential information about the scope of the policy's coverage.
Step-by-step explanation:
Advertisements for accident and health policies that only cover a stated illness must prominently display a statement indicating that the policy is limited or specific to that illness and does not provide comprehensive health coverage. This is to ensure clarity and avoid misleading consumers who might assume that the policy provides broader coverage than it actually does. The purpose of such a disclaimer is to make sure that policyholders are well informed about the scope and limitations of their coverage.
