CIGNA HealthCare will be introducing a Web-based system that can help group health plan members set their own co-payments, coinsurance levels, deductibles and out-of-pocket maximums.

CIGNA HealthCare, Bloomfield, Conn., a unit of CIGNA Corp., Philadelphia, plans to start by offering the Web service through large, national employers in January 2007, the company says.

When workers use the CIGNA Custom Benefit Builder tool, the system will show workers how much the coverage will cost and give workers the ability to enroll for benefits, CIGNA HealthCare says.

CIGNA HealthCare is getting the technology for the tool from Choicelinx, Manchester, N.H., a CIGNA benefits technology subsidiary.
