View source for Definition:Medical Information Bureau (MIB)

🔍 '''Medical Information Bureau (MIB)''' is a membership-based organization that operates a confidential database used primarily by [[Definition:Life insurance | life]] and [[Definition:Health insurance | health]] insurers to detect inconsistencies and potential [[Definition:Insurance fraud | fraud]] in [[Definition:Insurance application | insurance applications]]. When an applicant discloses — or an [[Definition:Underwriting | underwriting]] process uncovers — certain medical conditions or lifestyle risk factors, member insurers may report coded information to MIB. Subsequent insurers reviewing a new application from the same individual can query the database to see whether prior applications revealed conditions that the applicant may have omitted, helping to maintain the integrity of the [[Definition:Risk selection | risk selection]] process.

⚙️ Participation works on a reciprocal basis: an [[Definition:Insurance carrier | insurer]] that queries MIB records is also expected to contribute relevant data from its own underwriting files. The information stored is not a medical record per se but rather a set of standardized codes indicating broad categories of health conditions, hazardous activities, or adverse driving histories. Underwriters cannot use an MIB code alone to decline coverage — they must independently verify any flagged condition through [[Definition:Medical underwriting | medical underwriting]] procedures such as attending physician statements, [[Definition:Paramedical examination | paramedical exams]], or laboratory tests. MIB also operates a checking account database that flags applications involving suspicious financial patterns.

📋 For the insurance industry, MIB serves as a critical safeguard against [[Definition:Adverse selection | adverse selection]] and [[Definition:Material misrepresentation | material misrepresentation]]. Without a centralized cross-referencing mechanism, applicants could conceal known conditions by simply applying to a different carrier. Consumer protection regulations require insurers to inform applicants that an MIB inquiry may be made and to provide individuals with the right to request their own MIB file and dispute inaccuracies. As [[Definition:Automated underwriting | automated underwriting]] and [[Definition:Accelerated underwriting | accelerated underwriting]] platforms become more prevalent in the [[Definition:Insurtech | insurtech]] space, MIB data feeds are increasingly integrated via APIs, enabling real-time checks that speed up the application process while preserving risk integrity.
