Who regulates health insurance companies?

Answer 1

In USA, Insurance is mostly regulated by states. Each state has insurance commissioner that regulates Life, health, property/casualty insurers, etc. Many Federal Laws (such as Serbanes-Oxley (SoX), Gramm-Leach-Bliley Act (GLBA), etc.), and federal agencies (such as IRS, SEC, etc.) also have a hand in regulating insurance companies. To help make insurance more uniform across the USA, National Association of Insurance Commissioners (NAIC) proposes regulation, which then each state's legislators have to approve.
