An insurance-industry veteran warned that a shared database could reveal discrepancies on coverage applications, prompting a discussion about what information insurers can access.
People also questioned what the database contains, particularly for retirees considering a change in Medicare supplement coverage.
Here's what to know
In a post on Reddit's r/medicare community, the original poster — who cited over 25 years of industry experience — described the Medical Information Bureau as a resource insurers use during underwriting, the process of reviewing health information to evaluate an application.
An application could be rejected if it conflicts with information an insurer receives, according to the OP. They said insurers jointly own MIB and likened it to a credit bureau.
Practices may differ by insurer. Generally, though, applicants or their physicians are asked to clarify potentially disqualifying information before an insurer decides whether to accept an application.

Users pushed back on the impression that MIB contains everyone's complete medical history.

"You will not have an MIB Consumer File unless you have applied for individually underwritten life or health insurance in the last seven years," one commenter said, citing the organization's website.
Beyond questions about medical records, participants raised concerns about the financial consequences of switching coverage. In particular, they questioned whether they could face underwriting if they tried to return to supplemental coverage.
One commenter favored keeping Medicare with supplemental coverage "as long as one can afford it."
What can be done?
The OP urged applicants to provide accurate information.
"If you try to lie on the application, and the information they receive does not match what you submitted, you will likely be automatically turned down, so don't lie," they said.
While one commenter said MIB offers the ability to request a file, others said information was stored as codes.
According to a description by the OP, MIB uses names and birth details — including birthplace — rather than Social Security numbers. A rejected application, they said, was a reason to review the file for errors.
"I pulled mine several years ago and it was blank," one user wrote.
