May 6 (Bloomberg) — Massachusetts' first-in-the-nation insurance exchange, which broke when the state changed it to comply with Obamacare, will be revamped or closed in favor of the U.S. enrollment system, officials said.

The state plans to pursue two options: building a new exchange using "off-the-shelf" technology, or joining the federal insurance marketplace, healthcare.gov. A final decision will be made this summer, Sarah Iselin, who oversees the exchange for Governor Deval Patrick, a Democrat, said in a phone interview. Massachusetts is the third state exchange to consider joining the federal system, after Oregon and Maryland.

"Each of them has different risks and different challenges," Iselin said. Joining the federal system for 2015 would be "a one-open-enrollment-period solution only," she said.
