The American Medical Association and other medical societies are suing another health insurer over allegations that the insurer has used illegal means to hold down rates paid to out-of-network doctors.
The plaintiffs filed the suit, against WellPoint Inc., Indianapolis, in the U.S. District Court in Los Angeles.
The plaintiffs are seeking court permission to represent a class of physicians affected by the WellPoint system for estimating typical rates for medical care.
WellPoint uses the estimates to determine how much it will pay for care provided by physicians outside its provider network.
