LEWISTON — Maine Community Health Options is offering health insurance plans throughout New Hampshire in 2015, expanding ahead of schedule after being approved for a $67 million loan from the U.S. Centers for Medicare and Medicaid Services.

The insurance cooperative’s proposed plans have been approved by the New Hampshire Insurance Department and are under review at CMS. It originally planned to start marketing its plans only in four of New Hampshire’s 10 counties.

The cooperative would be the fifth insurer participating under President Barack Obama’s health care overhaul law next year in New Hampshire.

The Portsmouth Press Herald reports in Maine, despite being a startup competing against longtime insurer Anthem, Maine Community Health Options captured 83 percent of the 44,000 Mainers who signed up for insurance on the marketplace in 2014.
