Some young people seeking to buy health insurance are finding themselves falling into a "subsidy gap" that leaves them ineligible for financial assistance that was heavily advertised.
Subsidies in the health law were designed to lower insurance costs for people who make around $11,000 to $46,000 a year.
But for young people earning toward the higher end of that range, it's more complicated than that. A new study shows that in major cities, some young people are fall in that salary range but don't actually qualify for government help to pay their insurance premiums.
And as the Affordable Care Act barrels toward its March 31 enrollment deadline, insurers need people age 18 to 34 to sign up.
Brian Loughnane is 26, and was making $36,000 a year when he looked for a policy on HealthCare.gov in December.
"There was something that said 'You're eligible for a subsidy.'" But then, the Philadelphia resident says, "After I put in the rest of my information, it said it was zero dollars."
That's because subsidies kick in only when a baseline health plan exceeds a certain percentage of a person's income. The higher a person's income, the more expensive premiums must be before subsidies kick in. That's the young person's subsidy gap.
"What we found is that on average, once you were above $31,744 you probably were not going to qualify for a subsidy," says Kev Coleman, with the health information technology company Healthpocket. He looked at plans for young adults in eight major cities, and all of them had these subsidy gaps.
This may mean there are enough low-cost insurance options being offered in those cities, that don't cost more than 10 percent of a person's income. But Coleman points out that depending on a person's age, income and city, premiums could be as much as $250 to $350 a month, and make up nearly 10 percent of income. Will young people perceive that as affordable?
"When you combine these results with the fact that young people under the age of 35 are statistically healthier, they probably place a lower priority on the need for health insurance – this may help explain why we're seeing an underenrollment in the younger adults, versus the targets originally set by the [Obama] administration," Coleman says.
In Philadelphia, the region's largest insurer doesn't seem too worried about this.
"We're looking to get as many people as insured as possible, [to] make sure they're aware the deadline is coming," says Koleen Cavanaugh, a director of marketing for Independence Blue Cross, one of two companies offering plans on Philadelphia's exchange. She says more than 90,000 people in the region, across all ages, have enrolled in their plans since Oct. 1, 2013, the beginning of open enrollment.
"Back in January if we looked at the numbers, we had about 21 percent enrollment in the millennial population, we're now around 31 percent, so we've seen a nice uptick in February and March enrollment numbers," Cavanaugh says, as she works in a tent near City Hall where agents are helping people sign up.
According to Cavanaugh, the majority of those young adults have been eligible for subsidies.
An earlier government study found that about half of young adults nationwide are eligible for a basic plan that costs $50 a month or less. But that does not include Brian Loughnane, who was aging out of his parent's plan. He works for a tech startup that doesn't offer insurance. "I was a completely new entrant into the marketplace so I didn't really have an idea of what I would be paying," he says.
Loughnane found a mid-level silver plan at full cost for $205 a month. Analysts like Coleman worry that might be too much for some young people and will keep them from signing up for coverage. For Loughnane, it's worth paying for it even though he's healthy. He wants coverage, in part because he saw how important insurance was for his girlfriend.
"You know she had cancer and she beat it," Loughnane says. "That's a situation where without health insurance, you're going to get into debt for the rest of your life."
The $200 a month plan was easy sell: "That's less than half of what I pay each month for groceries, I have other expenses too, but for my health I'm absolutely willing to pay that."
He acknowledges other factors in his favor include Philadelphia's relatively low cost of living and not having any major debts.
