An insurance industry source of information about a proposed insured's medical information for underwriting is called the?

The Medical Information Bureau (MIB) plays a crucial role in the underwriting process of life insurance by providing a centralized source of medical information about individuals who are applying for insurance coverage. Insurers utilize the MIB to obtain an applicant's medical history, including past claims and treatments that may not be reported on the application.

This service helps insurers assess risk more effectively, as it enables them to verify the information provided by applicants and identify any potential discrepancies. By accessing the MIB, insurers can make informed decisions regarding coverage offerings and premium pricing.

The other options, while related to personal information, do not specifically serve the same purpose in underwriting as the MIB. Doctor's records are specific to an individual and may not be readily accessible to all insurers. The Social Security Administration primarily handles issues regarding social security benefits and does not focus on medical underwriting. The Medical Depository Bureau is not a recognized term in insurance, and thus does not represent a source of underwriting information.
