A new state law requiring some health insurance plans to extend coverage of Wisconsin health insurance for adult children younger than 27 only applies to about 35 percent of those who are insured in the state.
However, it does not apply to private self-funded plans that many employers use and which make up about 42 percent of the state’s Wisconsin health insurance market.
About 28 percent of those with Wisconsin health insurance have conventional fully insured plans, with the rest receiving coverage from private self-funded plans and self-funded plans used for state, local and school district employees.
Many insurers in the state already covered adult children up to the age of 24, if they were full-time students, prior to this law. Other states, including Illinois health insurance, also have extended coverage to adult children.
