UnitedHealth Group Chief Executive Stephen Hemsley pulled in $102 million in 2009, with $98.6 million coming from exercised stock options, according to a filing with the Securities and Exchange Commission. That is the biggest payday at the Minnetonka, MN-based health insurer since 2006, when former chief Dr. William McGuire collected $127 million. Health insurers have been under the gun this year with regulators demanding explanations for rate increases and legislators taking aim at insurance company profits through healthcare reform legislation, the Minneapolis Star Tribune reports.
