If you’ve ever applied for life or health insurance, you likely agreed — perhaps without noticing — to let the insurer check your file with the Medical Information Bureau. Here’s what that means and why it’s nothing to worry about.
A credit bureau, but for insurance
The Medical Information Bureau (MIB) is a member-owned nonprofit that has served insurers since 1902 — think of it as a credit bureau, but for insurance underwriting. When you apply for individually underwritten life, health, disability, critical illness, or long-term care coverage, member insurers can, with your written authorization, check your MIB record and report certain findings back.
Its job is to keep the system fair. By flagging discrepancies between what someone discloses on different applications, MIB helps prevent fraud — like hiding a condition to secure a lower premium. That protects honest applicants, who would otherwise pay higher rates to cover those risks.
What MIB does not have
Here’s where many people are pleasantly surprised. MIB does not pull records from your doctors or hospitals — no medical charts, lab results, or X-rays. It only holds coded information that member insurers have submitted, and only for people who applied for individually underwritten coverage in roughly the past seven years. Many people have no MIB file at all — which is completely normal.
What happens if there’s a discrepancy?
Sometimes an underwriter notices that your application doesn’t quite line up with your MIB record — maybe a condition shows up that wasn’t mentioned, or a date doesn’t match. If that happens, take a breath: it rarely means an automatic “no.”
An insurer can’t decline your application based on an MIB report alone. A discrepancy is simply a prompt to look closer. Usually the underwriter asks a follow-up question and the matter is cleared up quickly — often the “mismatch” is just a coding quirk, an outdated entry, or a misunderstanding.
If the record itself is wrong, you have the right to fix it. And if the discrepancy is real — say, a condition you’d forgotten to list — just explain it. Underwriters see this every day, and a straightforward answer keeps your application moving.
Your rights
Because MIB is a consumer reporting agency under the Fair Credit Reporting Act, you have real protections:
- Free annual report. You can request a free copy of your file once every 12 months.
- Review for accuracy. You can check exactly what, if anything, is on file.
- Dispute errors. If something looks wrong, you can file a dispute, and MIB must investigate and correct inaccurate information.
To request your report, call MIB at 1-866-692-6901 or visit mib.com.
