Clarifies prohibition on preexisting condition exclusions in health insurance policies. While the federal Affordable Care Act mandates that health insurers, except in certain grandfathered plans, may not include an exclusion for a preexisting condition in any insurance policy, New Jersey law was never changed to conform to the federal law. This bill revises the New Jersey law concerning group health insurance, the Individual Health Coverage Program, the Small Employer Health Benefits Program, and certain hospital, medical, and health service corporation plans to conform to the federal law regarding preexisting conditions.
