Please click here for our office hours at the Greeneville location and Johnson City location.
Our offices will be closed on Christmas Day, New Year’s Day, Thanksgiving Day [and the Friday following], Good Friday, Memorial Day, July 4th, and Labor Day.
Yes! At our Greeneville and Johnson City offices, evening hours are offered one day per week at each location, and Saturday morning hours are offered at each location once per month.
We may adjust this schedule as required by patient demand.
No, we are an appointment-only cardiovascular practice. Even though we require appointments, we strive to make them easy to schedule. It is our sincere goal to schedule routine patient appointments and tests in a timely fashion (within 2 weeks or so).
Not at all! We gladly welcome everyone, regardless of insurance status.
While patients who have high deductibles, or who are self-insured or uninsured will benefit the most from our practice model (from a financial standpoint), many patients choose to come here for other reasons, such as preferring extended appointment times to get to know their provider (and vice versa).
If you have a low-deductible or no-deductible insurance plan, but would still like to see one of our providers for office visits, we can utilize our hybrid approach for any testing that you may need. Click here to learn more.
No. We do not have contracts with any commercial health insurance companies, and therefore, we cannot accept those medical insurance plans (i.e. we cannot submit claims).
No. We do not have contracts with any type of government-funded health insurance.
No. We do not accept payments from Medicare, or any Medicare Advantage plans. We have ‘Opted Out’ of these programs. Please see our explanation as to what our opted-out status means, and how it affects our Medicare-covered patients.
Absolutely, yes. There are a few simple requirements that need be fulfilled to permit us to do so. Please read about our Hybrid Approach and our Opt-Out status for a more detailed explanation.
Yes. Even though our practice does not accept insurance payments, all patients are provided with a detailed receipt that lists courtesy ICD-10 codes (diagnosis codes), as well as related services and charges. Please note that we are considered “out of network” providers.
The receipt may be submitted by you to your insurance company for possible reimbursement — paid directly to you — or for application toward your insurance deductible. It may also be submitted to medical health sharing organizations for reimbursement.
*Please note that we cannot guarantee that your insurance provider will reimburse you for any appointments, testing, and/or treatments obtained from Trinity Heart and Vascular Group, or that they will apply related expenses to your deductible. The patient is strongly encouraged to contact their insurance provider for details regarding services rendered by out-of-network providers.
‘Cash-based’ means that you pay directly at the time of service, and while you are most welcome to pay with cash, we also have other convenient payment options available:
- Mastercard (credit or debit card)
- Visa (credit or debit card)
- American Express
- Apple Pay
- Google Pay
*Please note that if a debit and/or credit card is declined at the time of check-in for any reason, we may have to reschedule your appointment if cash payment cannot be made, or if the transaction remains unapproved following resubmission.
[Only established patients may pay by personal check. Please note that a $50 fee will be assessed should a check be returned for insufficient funds.]
To learn more about ‘cash pay / self pay,’ please click here.
No, you only pay once on the day of your appointment. For all office-based encounters, payments will be collected at check-in.
We will not send additional surprise bills in the mail. With our transparent pricing, you’ll know exactly what will be owed before you come to your appointment.
If add-on services (such as an EKG, echo contrast, or saline contrast) are potentially necessary, we will advise you beforehand via a “Good Faith Estimate,” as required by law.
Yes, you can use your HSA debit card for any office visits, tests, and exams at our practice.
Absolutely! We will readily send all medical notes and cardiovascular test results to any medical provider of your choosing. We will fax or e-mail your records (via HIPPA-compliant, encrypted e-mail).
Protecting your medical privacy is a top priority. To that end, we kindly ask that you sign a ‘Medical Release of Records’ consent form. You can rest assured that your medical information will only be shared with those you designate in writing, and only with your express consent.
[Rare exceptions include those as determined by law, and/or if there is a credible, immediate threat to the safety or health of others. Please see our HIPPA notice for complete details.]
If you believe that you’re experiencing a cardiac-related emergency, please call 911 or go to the nearest ER. Since we are a non-emergency facility, we only see patients during normal business hours for non-emergency needs.
Most, if not all, perceived cardiovascular symptoms (e.g., chest pain, palpitations, fainting spells, severe and abrupt extremity pain, shortness of breath, etc.) have potentially life-threatening causes, especially when associated with abrupt onset.
Given these realities, it is often difficult to adequately evaluate these symptoms over the phone, especially as timely testing for proper diagnosis is often required.
As such, all after-hours symptoms that significantly concern the patient should be evaluated at the nearest emergency facility.
Today, in most instances, when a patient is hospitalized, they are admitted by hospital-based providers who are referred to as ‘hospitalists.’
If you are admitted to the hospital for in-patient care, the hospitalist team will decide if a cardiology consultation is necessary. We enjoy collegial and collaborative relationships with other cardiovascular practices in our region, and one of these groups will take over in regards to your in-hospital consultation. They will provide your necessary cardiovascular care while you remain in the hospital, should you need it.
Please remind your hospital-based providers that you are a TH&VG patient, as this will facilitate appropriate post hospitalization follow-up and transfer of hospital records.
We are willing to refill your cardiovascular related medications, as long as you have been seen in our office within the past year. For certain medications, we may require a visit within the past 6 months.
Medications refill requests will be received during regular office hours, but no refill requests can be received after hours or on weekends.
We kindly ask that patients plan ahead regarding their prescription refills.
Please note, per practice policy, we DO NOT prescribe DEA scheduled medications (e.g., sedatives, narcotic pain medications, etc.). There will be no exceptions.
We’ve made the scheduling process as convenient as possible, and we give you the option to book an initial appointment in one of three ways.
1.) You can book an appointment with our Online Scheduler,
2.) You can book an appointment by phone at 423-588-5660, or
3.) You can request an appointment by making a request through our online form or via email.
For emailing, you may copy and paste this email address, and put it in the recipient line of your email: thvg.jane@
A staff member will follow-up with you in 1-2 business days or less to complete the onboarding process.
PLEASE NOTE: All visits for office evaluation or testing require a credit or debit card on file to reserve the time slot. Your card will not be billed unless our office ‘Cancellation – No Show Policy’ is violated.
[You may see a $1 or less “pending” charge on your credit card or bank statement when your card is added on file. This is a temporary authorization charge, and it will disappear from your statement, usually in a week or less.]
Yes! We’re happy to explain that here. To schedule a New Patient Consultation via our online scheduler (which is available 24 hours a day, 7 days a week), please go to our app page, and click the blue ‘Book an Appointment’ button for the office location that you want to go to (Greeneville or Johnson City).
Next, select ‘Initial Patient Evaluation’ with either Dr. Daniel O’Roark, or Mr. Nolan Hensley, PA-C.
[If you are a student athlete, and need a cardiac evaluation, please choose ‘Athletic Competition Cardiovascular Risk Assessment.’]
Once you are an established patient (and have created an account in the Jane app), you can schedule follow-up visits, reschedule, or cancel office visits and other appointment types from the ‘My Account’ patient portal.
If you are an established patient at our practice, and Dr. O’Roark and/or Mr. Hensley has recommended a specific test, you may schedule it yourself online, over the phone, or in person at one of our office locations.
If you are not currently a patient at our practice, and one of your providers (such as a PCP or specialist) is recommending a cardiovascular test, you first need to obtain a written order from that referring provider. Once he or she has written an order for testing and has given it to you in a PDF, you can either:
1.) Call us at (423) 588-5660, or
2.) Email us at thvg.jane@
If you would prefer to use our online scheduler, please choose from one of the following categories:
- Nuclear Cardiology – this category can be chosen to schedule various types of stress tests
- Echocardiography/Vascular Imaging – this category can be chosen to schedule various types of echos and cardiac ultrasounds
- Miscellaneous Services – this category can be chosen for ECG/EKG and/or extended-wear cardiac monitors
[Please note that all stress tests and all stress echos are performed at the Greeneville office only. Regular/non-stress ‘comprehensive’ echos are preformed at both locations.]
After you choose the appropriate category and test, select your desired scheduling time. A staff member will follow-up with you within 1-2 business days to confirm the request, obtain your written order from your referring provider (if you used our online scheduler) and provide instructions as necessary.
Again, as a friendly reminder, if you are scheduling an in-office test, and you are not an established patient at our practice, you must be in possession of a written order from your medical provider.
You can contact us in one of three ways.
You can call us at 423-588-5660, or
Email us at provider.referral.mail@
Send us a fax at (423) 609-7905.
Please include the following information:
- Your name, phone number, and email address
- The first and last name of your patient
- Your patient’s date of birth, phone number, and e-mail address
- The symptoms and/or condition(s) you would like us to address. If the referral is for office-based testing only, please indicate the desired test(s).
Please also provide any cardiovascular test reports that you may have in your records.
We understand that schedules change, and we’re always willing to accommodate patients in these circumstances. If you realize that you have a scheduling conflict, please contact us as soon as possible to cancel or reschedule your appointment(s).
We must be contacted at least 24 hours before your scheduled appointment time (ideally sooner, if possible). If you notify us by voicemail or email at least 24 hours beforehand, there will not be any fees for that scheduled visit.
If you do not contact us, and/or do not show up for your office evaluation or test, you will be charged a $50 ‘No Show’ charge.
If the missed appointment is for a nuclear stress test, you will be charged an additional $125 for the unused isotope return charge fee. These charges MUST be paid in full before the test or any subsequent office visits can be scheduled or re-scheduled.
We value your time and your health, and in order for us to make sure that your medical needs are properly met, we block out generous appointment and/or procedural times. This ensures that we can provide the attention to detail your medical situation deserves.
If you don’t show up to your appointment without contacting us ahead of time, it blocks out an appointment slot that could have been given to another patient.
We never want an appointment time to be wasted because we’re passionate about providing cardiovascular care to as many patients as possible!
Additionally, if we have ‘No-Shows’ on a regular basis, we may be required to raise our prices for testing and office visits. We want to keep our prices as low as possible, and we can do that by avoiding unutilized appointment times.
