No. The individual mandate means you will have to get some form of health insurance, unless you qualify for an exemption. (See “Who must enroll? What if I don’t?”) But the marketplace is just one option for purchasing it on your own.
Insurers do not have to participate in the marketplace, so you still can buy health plans the same way you do today, directly from health insurers, or through your employer if offered. You also can still get public insurance, if you qualify, directly from Medicaid, Medicare, or other government agencies.
