It is now illegal for an insurance company to refuse to insure a large employer group of employees based on their health statuses. Insurance companies also cannot exclude an individual employee from the group insurance plan based on medical history. Additionally, it is the law that large employer group insurance be renewed every year, unless the employer chooses not to renew with that particular insurance company, the employer doesn’t pay the premium, the employer has committed fraud or intentional misrepresentation, or the employer has not complied with the terms of the contract.
