Abstract:
In December, Aetna became the latest insurer to agree to a proposed settlement to pay physicians and patients $120 million because it used Ingenix databases that deflated payments for out-of-network physician services. The decision stems from settlement of a 2009 lawsuit against Aetna by the Texas Medical Association, the American Medical Association, and state medical societies in California, Connecticut, Florida, Georgia, New Jersey, New York, North Carolina, Tennessee, and Washington. They alleged Aetna used databases created by Ingenix, Inc., a subsidiary of UnitedHealthcare, to set usual, customary, and reasonable (UCR) rates for out-of-network services. They said Ingenix was inherently flawed and unable to establish proper UCR rates.
