Lack of choice is not unusual. Half of the 48 states included in the study had 70 percent or more of the health insurance market concentrated into the two largest insurers.
Alabama had the least competitive health insurance market with two companies controlling 95 percent. Oregon has the most competitive market with the top two controlling 39 percent.
Blue Cross Blue Shield of South Carolina and United Healthcare control 78 percent of the health insurance business in South Carolina.
