What the government will require you to do:
• Sec. 202 (p. 91-92) of the bill requires you to enroll in a "qualified plan." If you get your insurance at work, your employer will have a "grace period" to switch you to a "qualified plan," meaning a plan designed by the Secretary of Health and Human Services. If you buy your own insurance, there's no grace period. You'll have to enroll in a qualified plan as soon as any term in your contract changes, such as the co-pay, deductible or benefit.
• Sec. 224 (p. 118) provides that 18 months after the bill becomes law, the Secretary of Health and Human Services will decide what a "qualified plan" covers and how much you'll be legally required to pay for it. That's like a banker telling you to sign the loan agreement now, then filling in the interest rate and repayment terms 18 months later.
