Aetna has joined other major health insurers in sounding a warning about the Affordable Care Act's public insurance exchanges.
The nation's third-largest insurer said Monday that it has been struggling with customers who sign up for coverage outside the ACA's annual enrollment window and then use a lot of care. This dumps claims on the insurer without providing enough premium revenue to counter those costs.
The ACA provides an annual enrollment window that gives people several weeks starting every fall in which they can buy coverage for the next year. The law established that window to prevent people from waiting until they become sick to buy insurance. But insurers say it has become too easy for customers to sign up outside of this window.
Customers are allowed to buy coverage outside that time frame if they lose a job, get divorced or have a child, among other reasons. Insurers want the federal government, which processes coverage applications in 38 states, to take a closer look at whether people actually qualify for these special enrollment periods when they apply for coverage.
Both Aetna and UnitedHealth Group Inc. said the exchange customers they get outside the annual enrollment window use more health care than those who sign up within it. This includes some cases where it appears that a customer bought coverage, used it and then dropped it.
"Insurance systems tend to get stressed when people can buy coverage when they know they need it and then drop it when they know they don't," Chief Financial Officer Shawn Guertin told The Associated Press.
The Centers for Medicare and Medicaid Services recently outlined several changes it said it was making to help shore up exchange enrollment windows.
Aetna is a big player in the ACA's state-based exchanges. It has enrolled about 750,000 people and is selling coverage in 15 states this year. It lost more than $100 million last year on its exchange business, which makes up a small part of its overall enrollment.
"We continue to have serious concerns about the sustainability of the public exchanges," Aetna Chairman and CEO Mark Bertolini said Monday.
Blue Cross-Blue Shield insurer Anthem Inc. also is paying close attention to how the government deals with special enrollment periods as it judges how sustainable the exchange business will be in the future, CEO Joseph Swedish said recently.
UnitedHealth Group has said it will decide this year whether to participate in the public exchanges in 2017.
Aetna leaders, who have publicly supported the exchanges in the past, say they are still committed and not ready yet to make that kind of call.
"It would be premature frankly to declare victory or defeat at this stage in the process," Guertin said.
