Excerpts from The Federal Register, 7 October 2009 (pdf, but a total page-turner):
Genetic information is defined, with respect to an individual, as information about the individual’s genetic tests or the genetic tests of family members, the manifestation of a disease or disorder in family members of such individual (that is, family medical history), or any request of or receipt by the individual or family members of genetic services. The definition further clarifies that genetic information does not include information about the sex or age of any individual.
A disease, disorder, or pathological condition is manifested when an individual has been or could reasonably be diagnosed by a health care professional with appropriate training and expertise in the field of medicine involved. However, the definition further provides that a disease, disorder, or pathological condition is not manifested if a diagnosis is based principally on genetic information.
GINA’s prohibition on the use and collection of genetic information could increase the potential for adverse selection in the individual health insurance market. Adverse selection arises when individuals seeking coverage have information about their health risks that issuers do not know.
To the extent that GINA and these interim final regulations prohibit group health plans and issuers from incentivizing employees to complete [health risk assessments] requesting genetic information including family medical history, and response rates for HRAs drop as a consequence, a cost may be incurred that is associated with the forgone benefits of identifying disease risks early and preventing their onset.
The more I read this statute, the less I like it.
