Empire State regulators say they expect insurers to respond quickly when informed about consumer complaints.

The New York State Insurance Department has imposed a $150,000 fine on CIGNA Corp., Philadelphia, in connection with allegations that CIGNA failed to respond within 15 days to a number of consumer complaints forwarded to it by the New York department’s Consumer Services Bureau.

CIGNA has agreed to a stipulation that requires it to take steps to prevent a recurrence of the customer service violations that initially prompted the New York department’s actions, department officials say.

New York law gives insurers and health maintenance organizations 15 business days to respond to complaints forwarded by the department.
