Blue Cross Blue Shield operates under the name Florida Blue in the Sunshine State.
The insurer's enrollment rose in recent years through the Affordable Care Act, said Paul Kluding, a company spokesman.
At the end of the open enrollment season on Jan. 31, 2017, Florida Blue had 940,000 ACA members — an increase from 715,000 in 2016. Florida Blue anticipated an increase because some other insurers, such as UnitedHealthCare and Aetna, exited the marketplace where consumers can shop for policies.
"The number fluctuates throughout the year, but historically the enrollment numbers actually increase within the few months following the open enrollment close date, so that number will probably rise slightly over the next couple of months," Kluding said.
Florida Blue sells plans in all Florida counties and is the largest insurer participating in the federal marketplace in Florida.
With all insurers combined, about 1.7 million Floridians enrolled through the federal health care law for 2017. So Florida Blue is the largest insurer on the marketplace.
Florida Blue made a small profit in the ACA market — a single-digit positive margin, Kluding said.
Sebelius' number about Florida Blue enrollment was close to the actual figure. But she is cherry-picking an example of an insurer that had success in a particular state.
Michael Tanner, a health policy expert at the libertarian Cato Institute, said that there are vast differences in how insurers fared in various states.
While Florida Blue may have done well, its counterpart in North Carolina "did terribly," he said.
In North Carolina, Blue Cross lost $405 million on medical expenses for ACA customers in 2014 and 2015 but stayed in the marketplace for 2017.
The majority of Blue Cross insurers in the states are non-profits, making comparisons to other providers difficult.
"It's a little bit apples and oranges to compare Blues to other insurers — they have a special non- profit status, and they are not taxed the same way. They have the largest market shares and historically being the insurer of last resort, their pool didn't change as radically as a lot of other insurance companies did," Tanner said.
UnitedHealthCare and Aetna exited the individual market, although Aetna is still writing off-exchange plans, said Amy Bogner, a spokeswoman for the Florida Office of Insurance Regulation. Humana withdrew from 31 of the 38 counties in the individual market in Florida and canceled all off-exchange business.
In August, Aetna CEO Mark Bertolini blamed a pre-tax loss of more than $430 million since January 2014 for the decision.
Her number is close. Florida Blue said 940,000 people enrolled as of Jan. 31, and the insurer expects the number to rise. It's also important to note that some other insurers have scaled back or dropped out of offering plans on the exchange.
The ruling: Her number is close. Florida Blue said 940,000 people enrolled as of Jan. 31, and the insurer expects the number to rise. It's also important to note that some other insurers have scaled back or dropped out of offering plans on the exchange.
