CONCORD, N.H. (AP) - Anthem Blue Cross and Blue Shield of New Hampshire is continuing to defend the limited provider network that will be available to those purchasing individual health insurance plans under the Affordable Care Act.

Anthem president Lisa Guertin told state senators Wednesday that concerns about access to care are magnified because Anthem will be the only company offering health plans through the new online market, but Anthem can't change that. The network includes 74 percent of the state's primary care providers and 16 of the state's 26 acute-care hospitals.

Alvin Felgar, president of Rochester's Frisbie Memorial Hospital, told Guertin it wasn't fair that his hospital wasn't even approached. But Guertin said the main driver was geography, and it that a narrower network was the only way to keep premiums affordable.
