A top executive is leaving one of the firms that helped to create the U.S. personal health account market.

Scott Spiker will be stepping down from his post as chief executive officer of Destiny Health, Chicago, in a few weeks, according to the firm’s parent company, Discovery Holdings Ltd., Sandton, South Africa.

Barry Swartzberg, executive director of Destiny Health, and Arthur Carols, the company’s chief actuarial officer, will run the company while Discovery is looking for a permanent chief executive, Discovery says.

Destiny Health is known for combining high-deductible plans, personal health accounts, and a Vitality points incentive program that encourages plan members to take steps to improve their health.

The company has been working closely with Guardian Life Insurance Company of America, New York, to set up account-based plans in Illinois, Maryland, Texas, Virginia and Washington.

Destiny Health plans also are sold in Wisconsin through insurance brokers and in Massachusetts through an arrangement with Tufts Health Plan, Waltham, Mass.
