Prescription Refills

It’s very important that you request your prescription refills during normal business hours before 4:30 p.m. Monday-Friday. Prescriptions will not be refilled on weekends or holidays.

You can request a refill on the MyCovenantHealth Patient Portal or by calling your pharmacy.

Referrals & Precertification


Insurers often require a physician referral prior to your visit to Knoxville Heart Group. 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 Knoxville Heart Group 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.

Patient Survey

Our Patients Are Important

We want to be your first and best choice for healthcare, and we need your feedback.

You will receive a text message or email asking you to complete a confidential and secure survey about your visit. Your feedback will help us continue to deliver excellent care. Thank you!
