Aetna Inc., Humana Inc., Cigna Corp. and other health insurers have to turn over more documents to the doctors suing them, a judge ruled. The physicians say the companies engaged in racketeering and broke contracts by not paying claims on time. U.S. District Judge Federico Moreno lifted a stay on discovery in the lawsuits, allowing lawyers to gather more evidence as they seek to prove that the suits qualify for class-action status.

Humana Inc., one of the nation's biggest health maintenance organizations, said Thursday that it will acquire Emphesys Financial Group Inc. for $650 million in cash.

Lawyers saying they represent 32 million members of managed health care plans have launched the largest legal assault yet on HMOs, filing class-action lawsuits against five of the industry's biggest players.

DaimlerChrysler reported an unexpected decline in profit for the second quarter as competition forced it to boost discounts on Chrysler vehicles and costs mounted for its Smart mini-car.

Humana Inc. said it had settled a six-year dispute with representatives of more than 700,000 physicians over reimbursement and would make a $40-million payment.
