What information is mainly held by the Medical Information Bureau?

The Medical Information Bureau (MIB) primarily holds confidential medical impairment information. This organization collects and shares data that helps insurance companies make informed decisions regarding underwriting and eligibility for life insurance policies. The purpose of this information is to flag any potential health issues or medical conditions that could affect a person's insurability.

This medical information is vital because it allows insurers to assess risk more accurately. By having access to a person's health history, including any significant medical conditions noted in previous insurance applications, insurers can determine appropriate premiums and coverage options.

The other options are less fitting because the MIB does not maintain claims history, which is typically stored by the insurance companies themselves. Likewise, while MIB does not hold details about specific insurance policies or consumer financial records, its focus is primarily on health-related information relevant to assessing the risk of insuring an individual.
