If you like your current plan, even if it is an Obamacare design, you probably can't keep it. If by chance that plan will continue next year, you might keep it via auto-enrollment.
But if you decide to change carriers, you might want to make sure you have enough money to pay double (or more) premiums for a few months.
Insurers expressed concern about consumers who choose to leave one health plan and sign up for another offered by a different insurance company. The federal government is not planning to send a notice to the first insurer terminating the consumer’s enrollment. As a result, consumers may receive bills or invoices from both companies. And conceivably, insurers said, if premiums are paid from bank accounts by electronic funds transfer, the money could be deducted twice.NYT
Isn't that swell?
First the government tells you that you MUST buy health insurance, then they abandon you on the renewal.
Put more lipstick on this pig.
