Letters of Medical Necessity

Many insurance plans require prior authorization in order to perform genetic testing. When a request for prior authorization is made, it’s important to include a letter of medical necessity that explains why Athena’s testing services are needed. Below you will find letters for several of Athena’s commonly ordered tests.

Use the letter with your initial request for prior authorization. If the insurance company denies your request, include the appeal letter with your appeal of their denial.
