This question provides an opportunity to show your advocacy for genetic testing, so take advantage of it! While you know that you can't change how insurers write their policies, you can play a part in ensuring that medical necessity is proven.

"I understand that my part as a physician concerning insurance coverage is typically proving a medical necessity, and this can get a bit tricky in genetic testing. While patient education is always important, this doesn't help how things are covered for them. I think this is where patient documentation and coding of services becomes very important, along with ensuring that patients do their due diligence in researching their coverage and talking with their insurer. I'd love to know more about how your residents and faculty interact with your billing department on patient coverage issues."
