What companies offer illness coverage?

Critical illness coverage is similar, but not identical to short term disability insurance and is offered by limited companies to cover all direct and indirect costs of a severe illness or injury that are not covered by general medical insurance. This includes things like rent, co-pays, etc. Cigna and Aflac are perhaps the two best known companies offering such policies. Humana also offers them. Most critical illness policies are not offered through employers and must be obtained individually.
