Detailing the winners: Which insurers scored the most health exchanges sign-ups

In California, it was Anthem Blue Cross, while Kaiser Permanente, Rocky Mountain Health Plans and the Colorado HealthOP appeared to fare well through that state's online insurance marketplace. Meanwhile, reports also track how the small business exchanges did in Rhode Island and Connecticut. 

Los Angeles Times: Anthem Blue Cross Signs Up The Most Californians Under Health Law
With open enrollment for Obamacare wrapped up, insurance giant Anthem Blue Cross stayed ahead of the pack in California sign-ups and widened its lead over rival Blue Shield of California. Anthem signed up 425,058 people through April 15, or 30.5% of Covered California's exchange market under the Affordable Care Act, new data show. Anthem is a unit of Indianapolis-based WellPoint Inc., the nation's second-largest health insurer (Terhune, 4/21). 

The Miami Herald:  Florida Blue Says ACA Enrollments Exceeded Expectations But Premiums May Rise In 2015
Most of the consumers who bought a private health plan from Florida Blue through the Affordable Care Act's insurance exchanges between October and April were previously uninsured -; one of many factors potentially leading to higher premium rates in 2015, according to a senior executive (Chang and Borns, 4/21).

Health News Colorado: Kaiser, Other Nonprofits Score Majority Of Exchange Sign-Ups
Nearly three out of four people who bought private health insurance through Colorado's exchange selected nonprofit carriers: Kaiser Permanente, Rocky Mountain Health Plans and the Colorado HealthOP. Nearly half picked Kaiser. Kaiser enrolled 58,344 of 127,233 people -; or about 46 percent -; of those who bought insurance through Connect for Health Colorado between Oct. 1 and the end of open enrollment on March 31 (McCrimmon, 4/21).

Politico Pro: Rhode Island Shines In The SHOP Spotlight
The smallest state in the nation may be able to boast the greatest progress in an Obamacare initiative aimed at, yes, small businesses. Many states pushed their small-business health options programs to the side amid the myriad problems that arose while they were gearing up for the law's first enrollment season. But Rhode Island put SHOP front and center, and half a year later, its program has signed up a bigger percentage of the population than that of any other state (Villacorta, 4/21).

The CT Mirror: CT Obamacare Exchange Lags In Attracting Small Businesses
Access Health CT, the state's health insurance exchange, drew national praise for its performance in enrolling more than 208,000 individuals in health care coverage as part of the law commonly known as Obamacare. But the small business side of the state's exchange -- known as SHOP, for the Small Business Health Options Program -- hasn't done so well. As of April 8, it had sold plans to 78 businesses, covering a total of 330 people (Becker, 4/21).
