Humana to buy OSF HealthPlans insurer

Louisville, KY-based managed care company Humana Inc. has announced plans to buy Peoria,IL-based health insurer OSF HealthPlans for about $90 million. The deal means OSF HealthPlans parent, hospital operator OSF Healthcare, will be exiting the health insurance business. The move reflects a trend seen in the last several years of providers of medical-care to focus on their core business of providing care rather than paying for medical-care service.
