This year, 160 million Americans will purchase health insurance policies. By 2019, the number will climb to 188 million Americans. An investigation by Congress found that the largest U.S. for-profit health insurance companies routinely denied coverage to millions of Americans based on pre-existing conditions, or errors and omissions. We work with clients at all insurance companies, including Aetna, Blue Cross Blue Shield, CIGNA, Highmark, Humana, Kaiser, UnitedHealthcare and WellPoint.
