Supreme Court, Health Insurers | featured news

Insurance companies hailed the Supreme Court's ruling upholding the Affordable Care Act, saying it gives them certainty about the rules they'll face as they push to cut administrative costs and reward doctors who contain health care costs by emphasizing preventive care.

Stocks of hospital companies rose sharply and insurance companies fell Thursday after the Supreme Court upheld a requirement that almost all Americans carry health insurance. The stock of Hospital Corp. of America, the largest private hospital chain in the United States, rose a little more than 7 percent. Quest Diagnostics, which runs laboratories, rose almost 3 percent.

Insurer UnitedHealth Group sees some parts of the health care overhaul as sound medicine and plans to keep them regardless of whether the law survives an upcoming Supreme Court ruling.
