"...extending such coverage in child-only policies “provides a very powerful incentive for a parent to wait until their child becomes very sick before purchasing coverage.”
Zirkelbach added that in 2014, when similar protections kick in for all individuals with preexisting conditions, virtually all Americans will be required to get health insurance.
With no such mandate currently in place, however, the result over the next several years could be that the pool of children insured by child-only plans would rapidly skew toward those with expensive medical bills, either bankrupting the plans or forcing insurers to make up their losses by substantially increasing premiums for all customers. And Zirkelbach said the effect could be compounded if only a few plans remain in the market."
