Sen. John Rockefeller IV is looking more closely at how health plans pay for out-of-network care.
Rockefeller, chairman of the U.S. Senate Commerce, Science and Transportation Committee, has sent letters to 18 insurers asking them about the data they use to determine reimbursement rates.
The recipients of the letters include several large Blue Cross and Blue Shield companies along with health insurers outside the Blue Cross and Blue Shield system, such as Humana Inc., Louisville, Ky., and Kaiser Permanente, Oakland, Calif., according to Commerce Committee officials.
The list also includes companies not commonly thought of as being health insurers, such as American International Group Inc., New York; MetLife Inc., New York; and Unum Group Corp., Chattanooga, Tenn.
