Who stores your health information?

In your quest to be an educated patient, you may want to know about the MIB. Not the Men in Black, but the Medical Information Bureau. If you apply for insurance (be it health, life, or disability) and are denied, they may have the reason for denial stored as a code, which can be accessed by its 600 member companies (i.e. insurance agencies that you may wish to apply to in the future).
You are allowed one free look at your file per year. If you haven't been denied healthcare, you may not have a record. To request your record, go here.
