In TN, limited patient options bring some of the country's cheapest premiums

Chattanooga's success in achieving bargain-priced policies offers valuable lessons for other parts of the country as they seek to satisfy consumers with insurance networks that limit their choices of doctors and hospitals. Nationwide, about 70 percent of the lowest-priced plans included narrow networks, according to the consultants McKinsey & Company. But few places have put them into place as successfully as here in Eastern Tennessee, where BlueCross BlueShield of Tennessee, the area's dominant insurer, cut a low price deal with one of the three big hospital systems to be the sole provider in their cheapest network.
