While genetic testing is receiving attention in the press and trade journals, its promotion by plan sponsors still remains in its infancy. When asked about their current approach to the use of diagnostic tests to identify genetic variations in patients that may impact how effectively a drug works, only 7% of employers said they currently provide coverage for genetic tests, with 11% considering a formal approach to the issue.

A limitation of this question is that many employers may simply not be aware of the current coverage rules under the medical benefit.
