The Geisinger Health Plan foresees health costs rising 7.5% next year, but requested a 40% rate increase. The plan, which is run by one of the nation’s top-rated health organizations, underestimated the cost of covering the newly insured under ObamaCare. “Our rates for Medicare, Medicaid and employer-sponsored insurance have been relatively stable, but those products have to bear the cost of our losses on exchange business,” Kurt Wrobel, Geisinger’s chief actuary, said. Many insurers are struggling to find the best ways of providing care to their new customers as they prepare for the fourth year of coverage under ObamaCare.
