One of those areas could be mental health care. An NBC report points out mental health problems are on the rise among college students. Citing data from the National Alliance on Mental Illness, more than 75 percent of all mental health conditions begin before the age of 24 — making millennials, particularly those in college, most at risk.

The report also cites the Center for Collegiate Mental Health at Penn State University which says, based on data it gathers from 139 institutions, the number of students seeking help soared 50 percent between 2015 and 2016. Mental health care is not high on the priority list in the Senate bill.

Young adults, says KHN, could also be subject to other cost increases: larger deductibles, less help with out-of-pocket expenses, and for some, no subsidies to help pay for premiums, because the bill would reduce the income threshold for eligibility.

KHN reports approximately 27 percent of the 12.2 million consumers who signed up for health insurance through exchanges in 2017 were 18 to 34 years old. Covered California, the state’s exchange, put the number of its enrollees in that age group at 37 percent for this year.

It also cites Walter Zelman, chairman of the public health department at Cal State-Los Angeles, who says those who will face the most damage in the Senate bill are millennials covered by Medicaid. Not only does the Senate bill stop the expansion of Medicaid which was responsible for so many people signing up, but it cuts available funding for the program.
