HealthSpan, the insurance arm of Catholic health system Mercy Health, is getting rid of its medical group and halting sales of ObamaCare policies just two years after acquiring Kaiser Permanente’s Ohio subsidiary. Spokesman Chuck Heald said HealthSpan will stop selling individual and small-group health plans on the ObamaCare exchanges to focus more on Medicare and employer plans. HealthSpan jacked up premium rates for 2016 individual and small-group plans anywhere from 9% to 32% to account for the sicker-than-expected exchange population.
