Companies are seeking alternate health coverage offerings in the face of a shaky economy and the potential impact of the health care reform law, according to a new report by J.D. Power and Associates. The study found that employers are considering such options as defined contributions, vouchers and exchange purchasing in an effort to control spiraling health care costs. Employers, however, seem committed overall to continuing to offer health benefits. The study found that only 13 percent of fully insured employers and 14 percent of self-insured companies said they probably or definitely will not offer employer-sponsored benefits in the future.
