What is MIB in Insurance?
What is MIB in insurance? The Medical Information Bureau (MIB) is a central database that life and health insurance companies use during underwriting. At Diversified Insurance Brokers, we guide clients through this process and help them understand how the MIB works, what information is shared, and how it affects approvals and pricing for policies. Knowing how MIB data is used can give you an advantage when applying for high-risk life insurance or traditional coverage.
What is the MIB in Insurance?
The MIB is a nonprofit membership organization that collects and shares coded health information between insurance companies. Its purpose is to help insurers detect potential misrepresentations or omissions on applications. The MIB does not make decisions on coverage—it simply provides data that insurers can use as part of the underwriting process. A reference to past conditions, risky hobbies, or declined applications may appear in your MIB file.
Why Do Insurance Companies Use the MIB?
Life and health insurers rely on the MIB to ensure accurate underwriting. By verifying application information, the MIB reduces fraud and helps keep premiums fair. If one carrier has previously flagged an applicant for a condition such as diabetes, sleep apnea, or stroke history, other carriers may see a code related to that condition in the MIB database. This doesn’t automatically mean denial, but it can prompt further medical questions.
How Does MIB Data Affect Applicants?
Your MIB file may influence how smoothly your application moves through underwriting. If there’s a discrepancy between what you disclose and what’s on file, insurers may request additional medical exams, APS records, or lab work. However, applicants are entitled to request a free copy of their MIB report once a year, much like a credit report. Reviewing it allows you to correct errors before applying.
What Information Appears in an MIB Report?
- Medical impairments such as heart conditions, high blood pressure, or cancer history
- Risk factors like smoking, aviation, or hazardous hobbies
- Previous declined, rated, or modified insurance applications
- Prescription drug information (when reported by member companies)
It’s important to note that the MIB does not store full medical records, doctor notes, or lab results. Instead, it holds coded entries that alert underwriters to specific categories of risk.
Example: A Real-World Case
Imagine a 55-year-old applying for a $500,000 policy. The application states they are a non-smoker, but their MIB file indicates prior use of nicotine replacement therapy. The insurer may order a nicotine test. If the results are clean, coverage is approved at non-smoker rates. But if the test is positive, the insurer may classify them as a smoker. This highlights the importance of transparency and knowing what’s in your file.
How to Check and Correct Your MIB Record
Consumers can request a free annual report directly from the MIB website. If errors are found, the Fair Credit Reporting Act (FCRA) gives applicants the right to dispute and correct them. For those with complex health histories—such as applicants seeking life insurance with diabetic complications or coverage after an HIV diagnosis—it’s especially important to review and clarify records.
How the MIB Affects High-Risk Applicants
High-risk applicants may face more scrutiny through MIB checks, but that doesn’t mean coverage is impossible. At Diversified Insurance Brokers, we work with over 75 carriers to place challenging cases, even when MIB records contain red flags. Knowing which insurers are more flexible with certain medical codes, such as autism or mental health conditions, helps us secure approvals others can’t.
How MIB Impacts Burial and Final Expense Policies
For smaller policies, like burial insurance for overweight people or burial insurance with high blood pressure, the MIB may play a reduced role. Some simplified-issue or guaranteed-issue products do not use MIB at all, focusing instead on short health questionnaires or no underwriting. This makes them a fallback option for applicants with adverse MIB histories.
