Children's Pre-Existing Conditions


Uunder the Affordable Care Act, health plans cannot limit or deny benefits or deny coverage for a child younger than age 19 simply because the child has a “pre-existing condition” — that is, a health problem that developed before the child applied to join the plan.

What This Means for You

Until now, plans could refuse to accept anyone because of a pre-existing health condition, or they could limit benefits for that condition. Now, under the health care law, plans that cover children can no longer exclude, limit, or deny coverage to your child under age 19 solely based on a health problem or disability that your child developed before you applied for coverage. This rule applies to all job-related health plans as well as individual health insurance policies.

Some Important Details

  • This rule applies whether or not your child’s health problem or disability was discovered or treated before you applied for coverage.
  • The new rule doesn’t apply to “grandfathered” individual health insurance policies. A grandfathered individual health insurance policy is a policy that you bought for yourself or your family (and is not a job-related health plan) on or before March 23, 2010. Coverage for adults may be available under the Pre-Existing Condition Insurance Plan.


On October 1, 2010, Sally purchased a new individual health policy for herself and her 13-year-old child, Miranda, who has been treated for asthma in the past. The new health policy excludes coverage for treatment of pre-existing conditions for all enrollees. On November 1, 2010 — one month after coverage began for Sally and Miranda—Miranda is hospitalized for an asthma attack. Her insurance company denies payment for the hospitalization, because under the policy Miranda’s asthma is considered a pre-existing condition. Under the new law, the insurer can’t deny payment for the hospitalization based on Miranda’s pre-existing asthma condition. Miranda is under the age of 19. Sally’s policy is new and therefore subject to the pre-existing condition rules of the new health care law. Sally’s policy year began after September 23, 2010, when the law’s rules on pre-existing conditions took effect.
