WellPoint Inc., the nation's biggest publicly traded health insurer, said Monday that it will pay as much as $198 million to settle two class-action lawsuits brought by representatives of more than 700,000 doctors over alleged unfair payment practices.

As part of the settlement, the Indianapolis-based company said it has agreed to pay $135 million to doctors and contribute $5 million to a non-profit foundation aimed at improving health care for the disadvantaged. It also said it would pay legal fees of as much as $58 million, in an amount to be determined by the court.

The physicians contended they have been systematically cheated by insurance companies that programmed computers to pay for less intensive services than were actually provided.

"While not perfect, this settlement promises unfettered physician-patient communication when it comes to discussing treatment options with their patients," said Dr. John Antalis, president of the Medical Association of Georgia, the first state medical association to sue the managed-care industry for improper payment practices.

The settlement will result in a pretax expense of $103 million, which will cut second-quarter earnings by 10 cents a share after taxes. WellPoint, with 28.5 million members, operates mainly under the names Blue Cross and Blue Shield.

If approved by U.S. District Judge Federico Moreno, the agreement will settle two national lawsuits against WellPoint Health Networks Inc. and Anthem Inc., which merged last year to create the current company.

One suit pitted a nationwide class of physicians against major national managed-care companies and a second against the Blue Cross Blue Shield Association and Blue Cross and Blue Shield companies.

Health Net, Prudential, Aetna and Cigna previously settled with the doctors. Coventry and United Health remain as defendants, with the case set for trial in Miami in September.

"Wellpoint obviously recognized that a costly trial of any of the disputed issues with physicians would not be in the interest of the company," said Archie Lamb, one of the attorneys for the doctors. "This agreement advances a very basic principle: that the physicians' input is a critical part of the health-care system."

Larry C. Glasscock, president and chief executive of WellPoint, said the settlement is "a very important step in further collaborating with physicians." The statement did not acknowledge any wrongdoing by the company.
