What is the age cutoff of a child's health insurance under parents plan?

I just heard that President Obama signed into law that allows health insurance coverage for a child under a parents policy up to age 27. Is that correct?

Have a check first with your insurance company or your insurance agent. It actually depends on the insurance that your parents enrolled but usually 22 will be the cut off. If in college, you can still be covered provided that the insurance is permitting it ;) You can also find additional information on this one when you read on this site that i use for insurance references ;) Hope this one helps! Goodluck on you :)
