The MIB Report: The Quiet File That Sets Your Texas Life Insurance Rate

What is the MIB report, and what does it disclose?

The Medical Information Bureau is a nonprofit consortium of life and health insurance carriers founded in 1902. Member carriers report selected coded information from every application they receive, and pull the consolidated file on every new application.

MIB does not store full medical records. It stores short alphanumeric codes representing specific conditions disclosed, lab values flagged, prior declines or postponements, and risky-activity disclosures (aviation, scuba, racing).

Records persist for 7 years from the application date. An entry that was material 5 years ago is still material today.

What MIB stores in practice

Common codes: hypertension, controlled vs uncontrolled. Diabetes type and control. Cholesterol level brackets. BMI ranges. Specific cancer diagnoses by location and stage. Mental health diagnoses by category. Substance use disclosed. Driving history if disclosed. Recreational risk activities disclosed.

MIB does not store the underlying medical record. It stores the fact that you (or another carrier reviewing your APS) disclosed a particular condition at a particular point in time.

Critically, MIB does store declines and postponements from any member carrier. A decline from one carrier is visible to every other carrier for 7 years — this is why shotgun applications are catastrophic for your future insurability.

Why this matters in Texas

Texas Insurance Code §705.005 and §1131.104 together let a carrier rescind a policy within two years for material misrepresentation. An MIB mismatch between what you disclosed on a prior application and what you disclose on the current one is the single most common rescission trigger in Texas.

Pulling your file before applying lets you identify and correct inaccurate entries through MIB's free dispute process (90-day standard turnaround) and ensure your current application is consistent with what is already on file.

If a prior carrier coded a condition you do not actually have — which happens — you have the right to dispute it. The dispute either succeeds (the code is corrected) or fails (MIB notes the dispute), but either way it puts you on stronger ground than ignoring the discrepancy.

The most common MIB surprises

A prior 'no decision' application that was actually a postpone — and now lives as a postpone code. Many applicants withdraw applications and never realize the carrier already reported.

A miscoded condition from a prior paramed (elevated blood pressure on one reading that became a 'hypertension' code).

An old condition that you have since resolved but is still on file with no resolution code.

A risk activity disclosed years ago (scuba, motorcycle, private pilot) that you no longer pursue.

What MIB is not: the three other files carriers pull

MIB is only one of four data sources on a standard Texas application, and it is the least detailed of them. Your prescription history, pulled through Milliman IntelliScript or ScriptCheck, covers roughly five to seven years of filled prescriptions with drug name, dosage, and refill pattern — far more revealing than an MIB code, because dosage and refill frequency tell an underwriter how severe and how well-controlled a condition is.

Your motor vehicle record comes from the Texas Department of Public Safety and shows convictions, license suspensions, and DWI dispositions. Carriers typically look back three to ten years depending on the product.

The Attending Physician Statement is the deepest source: your actual chart notes, lab panels, imaging, referrals, and hospitalizations from each treating provider. When an MIB code raises a question, the APS is how the carrier answers it. Our underwriting guide breaks down all four sources and the look-back period for each.

How do you read your decoded MIB letter?

MIB returns codes, not sentences, and the decoded letter it mails you translates each one into a plain-language description plus the date it was reported and the type of carrier that reported it. Codes carry a severity or qualifier digit — the difference between a hypertension code flagged as controlled and the same condition flagged as uncontrolled changes how the next underwriter reads it.

Check three things on every line. First, the date: does an application actually exist in your memory from that month? Second, the condition: is it a diagnosis you have, or a symptom that was ruled out? Third, the follow-up code: declines, postpones, and requests for additional information all report separately from medical conditions.

If the letter shows no records at all, that is normal for anyone who has never applied for individually underwritten life, health, disability, or long-term care coverage. Group coverage through an employer does not generate MIB entries.

How do you dispute an MIB entry?

Under the Fair Credit Reporting Act, MIB must investigate a written dispute and either correct the entry or note your statement of disagreement in the file. Send the dispute in writing, name the specific code and reporting date, and attach documentation — a physician letter confirming a condition was ruled out, a lab panel showing normal values, or a copy of the corrected medical record.

MIB does not adjudicate the medicine. It contacts the reporting member carrier, and the carrier either confirms or corrects what it submitted. That means the strongest dispute is one where your own physician's records contradict what the carrier reported.

If the dispute fails, you are not out of options. A brief cover letter from your physician submitted with the next application explains the discrepancy directly to the underwriter, who has discretion the MIB process does not.

How to sequence applications so MIB works for you

The discipline that protects your MIB file is simple: never submit more than one formal application at a time, and never submit one at all until a broker has informally pre-shopped your profile. Informal inquiries, where a broker describes the case to an underwriter without identifying you, generate no MIB entry and no decline.

A single decline reported to MIB is visible to every member carrier for seven years, and subsequent carriers frequently decline on the strength of the prior decline alone. That cascade is the most expensive mistake an impaired-risk applicant can make, and it is entirely avoidable.

If you already carry a decline, the path forward is a broker who targets the specific carriers whose published guidelines tolerate your condition, submits with a cover letter addressing the prior decline directly, and waits for any postpone window to close before applying again.
