But if you become ill, your bills could be very high. If you have insurance, many of your costs are covered by a third-party payer, not by you. A third-party payer can be an insurance company or, in some cases, it can be your employer. Most Americans get health insurance through their jobs or are covered because a family member has insurance at work. This is called group insurance.
Group insurance is generally the least expensive kind.
In many cases, the employer pays part or all of the cost. Some employers offer only one health insurance plan. You will lose your employer- supported group coverage. It may be possible to keep the same policy, but you will have to pay for it yourself. This will certainly cost you more than group coverage for the same, or less, protection.
