Referrals & Precertification


Insurers often require a physician referral prior to your visit to Oak Ridge Gastroenterology Associates. As a courtesy to our patients, we will attempt to contact your primary care physician and request a referral. However, it is your responsibility to confirm that a referral has been obtained before you are seen by our providers.


If a test or procedure is ordered by a Oak Ridge Gastroenterology provider, our staff will obtain a necessary precertification on your behalf. Precertification for any tests or procedures ordered by your own primary care physician is the responsibility of your primary care provider’s office.
