Final answer:
The true statement about Blanket health insurance is that it covers a changing group of people, hence the correct answer is D. A blanket policy covers a changing group of people.
Explanation:
Blanket health insurance is designed to provide coverage for a group whose membership may change frequently, such as employees of a company or participants in an event. Unlike individual insurance policies where the insured persons are named, blanket insurance does not specifically list individuals as it is meant to cover all persons in the defined group at any given time.
Hence, option B is not true for blanket policies as they do not specify individuals. This type of coverage adjusts as people enter or leave the group, making options A and C incorrect since benefits do not change just because the group changes, and there is not a set 'specific number' of insureds covered under a blanket policy.
Health insurance complexities arise from the myriad of plans available and the different costs that can occur out-of-pocket. Rates can vary for a number of reasons such as employment status, with group policies often offering more favorable rates than individual policies due to risk diversification and administrative efficiencies. Regulatory measures within the industry also influence how policies are handled, particularly regarding issues such as coverage of preexisting conditions and the setting or changing of insurance premiums.
