Main purpose of MIB in underwriting?

• A. To regulate the insurance market
• B. To provide a centralized source of adverse medical information to help decide whether to issue coverage
• C. To set premium brackets
• D. To evaluate driving records

Answer: (B)

Underwriting relies on accurate health information, and the MIB serves as a centralized source of adverse medical information to help underwriters decide whether to issue coverage. It collects standardized medical impairment items from member insurers, enabling underwriters to see disclosed issues, verify consistency, and catch undisclosed or evolving medical risks that could affect insurability. This helps produce more informed, consistent underwriting decisions and reduces the risk of misrepresentation or undisclosed conditions.

It’s not about regulating the insurance market, setting premium brackets, or evaluating driving records—the MIB’s purpose is specifically to provide medical information that can influence underwriting decisions.
