If you are not aware of the MIB when it comes to health insurance, read this...BD
I have heard people mention the MIB as a source, but where do they get their info? I thought medical records were strictly private, how do they find out your past medical info?
Records are private between you and your insuring company and any company you apply for coverage with. Your prescription history is also reported to the MIB.
Insurance companies keep databases of claims experience that they upload to the Medical Information Bureau. So for example, if Anthem has claims experience on you, they upload it to the bureau and United healthcare can then access your claims experience data.
