Yes, federal laws protect you if you have a pre-existing condition and want to change jobs. The 1996 Health Insurance Portability and Accountability Act (HIPAA) ensures that your new health plan cannot deny you coverage based on your health status when you are moving from one group health plan to another. Pre-existing conditions must be covered by the new health plan. HIPAA is a federal law that applies to group health plans in all fifty states but the interpretation varies among states. Contact your state's health plan regulatory agency for information on the interpretations and applications in your state.
