Medscape Medical News reports that clinicians who have been paid by UnitedHealth Group for out-of-network services have until Oct. 5 to file a claim in the $350-million settlement of a class-action lawsuit alleging that the insurer systematically underpaid for out-of-network care.

The settlement covers clinicians who filed out-of-network claims not only with UnitedHealth Group but also its subsidiaries and affiliates, which include Oxford Health Plans, Golden Rule Insurance, Mid-Atlantic Medical Services, and PacifiCare Health Systems.

The claims must apply to services or supplies provided between March 15, 1994, and Nov. 18, 2009. The article estimates that a typical physician filing a claim might receive between $1,000 and $1,500. For more information visit the American Medical Association website.
