In Nebraska can a child at the age of 26 still be under parents plan?

As of the child's 26th birthday, he cannot be covered under his parent's health plan. Generally, the health insurer will cover the child under the end of the month of the 26th birthday. If the plan is required to offer COBRA continuation coverage, it would be offered at that time. (Not all plans are required to offer COBRA; ask your employer.)

If you lived in New York or New Jersey, the child could stay on your plan until he turns 30!
