Health Care Service Corp. has agreed to build access to health savings account services from HSA Bank into its member Web portal system.

The deal means that holders of HSA-compatible health insurance policies issued by units of Health Care Service, Chicago, will have an easier time getting health plan and HSA information from the same Web site, according to HSA Bank, a unit of Webster Financial Corp., Waterbury, Conn.

Health Care Service is the parent of the Blue Cross and Blue Shield plans in Illinois, Texas and other states.
