Thanks to a fairly recent change in federal law, if you have accounts that are medical in nature (such as money you owe, outstanding debt, etc), your credit report can't reveal any identifying information about the creditor.

Example: let's say you got medical treatment from Ellis Fischel Cancer Center in Columbia, and you are paying for your treatment in installments. Or perhaps you failed to pay your bill at the Mid Missouri Substance Abuse Center (just made that name up). On your credit report, you should see an entry that's designated as medical, but doesn't name those companies or give their contact information.

This is to protect your medical privacy, so that anyone checking your credit report won't learn anything about your medical condition. They will just learn that you owe money to some kind of medical organization. The amount of debt will show up, along with any history of payments good or bad.
