That is good advice if you know in advance that you won't get sick until the annual open enrollment period.
If you don't already have coverage through your job, your spouse's job or your parent's insurance, then you can apply for coverage on the exchanges, but only during the annual "
open enrollment" period, which for the first year only is six months starting on October 1 and for every later year is approximately two months starting in October. There are
some special exceptions for major life changes, but you should not count on qualifying for those.
If you apply for coverage outside of the open enrollment period, you won't be able to use the exchanges to find coverage and you'll have to deal directly with the insurance companies. Even then, Obamacare prohibits most insurance plans from denying coverage based on preexisting conditions, but you will not qualify for any premium subsidies, even if your income is low enough that you would owe the minimum 2%, which might be the case if you are sick. The premium subsidies are available for people with an income below 400% of the poverty level.
If you do not buy at least a silver plan through the exchanges, then you will not be eligible for the "
cost sharing reductions" available to some low income people. The cost sharing reductions reduce your deductible and out-of-pocked amount, if your income is below 250% of the poverty level.
If you do not want to buy the basic bronze plan, then you could consider a "
catastrophic plan," which will be available to people under age 30.
