Private health insurance

" Individuals who buy coverage directly from a health insurer are often denied coverage due to a pre-existing condition during a process called medical underwriting, which assesses an applicant's health status and other risk factors. Beginning January 1, 2014, the Patient Protection and Affordable Care Act (PPACA) prohibits health insurers in the individual market from denying coverage, increasing premiums, or restricting benefits because of a pre-existing condition. GAO was asked to examine the effect of this provision on adults who are 19-64 years old. GAO examined (1) the most common medical conditions that would cause an insurance company to restrict or deny insurance coverage for adults and the average annual costs associated with these conditions, (2) estimates of the number of adults with pre-existing conditions, and (3) the geographic and demographic profile of adults with pre-existing conditions. To address these three issues, GAO (1) identified four recent studies that narrowly or more broadly identified five lists of conditions likely to result in restricted coverage in the individual insurance market and (2) used the 2009 Medical Expenditure Panel Survey to generate five separate estimates, referred to as estimates 1 through 5. There is no commonly accepted list of pre-existing conditions because each insurer determines the conditions it will use for medical underwriting.
