Be Sure We Have Your Medical Records

If a physician has referred you to Legacy Heart Center, he/she will either contact us by phone or send your records to our office. It is very important that we receive your medical records prior to your visit. Otherwise, your cardiologist will be unable to adequately evaluate you and it may be necessary to reschedule your appointment until those records are received. If you have referred yourself, you should contact your physician and arrange for your records to be sent to our office before your scheduled visit. A few days prior to your appointment, please check with your physician or our office to ensure that your records have been sent and received.

Bring All Of Your Insurance Information And Your Driver’s License

When you make an appointment with us, you will be asked for your insurance information that will then be verified by us prior to your appointment. You should bring your insurance card and your driver’s license to your first appointment.

Bring All Of Your Medications

Please bring all of your medications with you in their original containers when you come to the office. Just put them into a plastic bag and bring them along so that your cardiologist will know everything that you are currently taking. Make sure your doctor knows about every drug you are taking, including over-the-counter drugs and herbal medications as well. One drug may interact with another, in some cases creating serious medical problems.

Complete The New Patient Forms

Your health history and registration information is very important. We ask that you complete and submit the New Patient Questionnaire online as soon as possible after scheduling your appointment. This will expedite the check-in process when you arrive. Please print and complete all other forms prior to your visit. 

If you have any questions about the forms, please call our office, 469.800.6477.

Your Examination: What To Expect

Once you have completed the check-in process, a medical assistant will take you back to an exam room where he or she will take your blood pressure and pulse and do a 12-lead electrocardiogram (EKG) on you. Please do not use any body lotions or oils prior to your office visit as this makes it difficult to perform an EKG. This test is not painful and takes approximately 5-10 minutes to perform.

The medical assistant will also take your medical history to find out not only what medications you’re taking but what, if any, allergies you might have; what kind of prior illnesses or injuries you may have suffered; and any surgeries or hospital stays you may have had.

You’ll also be asked about the health of your family including any hereditary conditions that may be related to your cardiac health. Finally, you’ll be asked about your marital status, employment and whether or not you use tobacco, alcohol or any drugs. It may help to write down all of your medical events and dates and bring this with you to your visit.

Once the medical assistant is finished, the cardiologist will meet with you to review your medical history and perform a physical examination. Following the exam, he or she will discuss the findings with you and recommend any further testing or treatment plans. Please feel free to ask the cardiologist any questions you may have at this time. On occasion, our physicians utilize certified Physician Assistants specially trained in cardiovascular care to see their patients. If that is the case, your visit will then be reviewed by your physician.

What Happens After The First Visit?

After your visit with the cardiologist, our office will forward all cardiac records, test results, and suggestions for treatment to your referring physician. In some cases, we may need to schedule a return visit for additional tests. We have an array of advanced technology diagnostic testing and procedure options available on-site to help us pinpoint problems and act on them quickly, well in advance of any cardiac incident.

If you have questions, please call your cardiologist’s nurse, 469.800.6300. Any call received after 4:00 p.m. will normally be returned the following business day. Every attempt will be made to return your call in a timely manner.

Insurance and Billing

Legacy Heart Center is dedicated to providing the best possible care and service to you and we regard your complete understanding of your financial responsibilities as an essential element of your care and treatment.

As a courtesy to our patients, we will file your insurance; however, patients are responsible for paying deductibles, co-pays, and any portion of the claim that is not covered by the insurance company.

All patients are asked to inform Check-in if your insurance has changed.

If you have any questions regarding the following financial policy, please contact our Billing Office Supervisor, 469.800.6478.

Financial Policy

Full payment is due at the time of service unless other arrangements have been made in advance by either yourself or your health coverage carrier. For your convenience we accept Visa, MasterCard, American Express and Discover.

Your insurance policy is a contract between you and your insurance company. There are times when you may need to involve your employer to answer policy coverage issues.

We will file your primary and secondary insurances. In the case that we verified your insurance and they only reimburse the patient, we will file your claim but expect to be paid for our services at the time of your appointment.

Deductibles And Non-Covered Services

Legacy Heart Center is contracted with several insurance carriers. What this means to our patients is that Legacy has agreed with your carrier on a negotiated rate and that our patients are responsible for their deductible, any non-covered service and their co-pay.

We must collect the co-payment/deductible portion when you arrive for your appointment as per our contract with your insurance carrier. (Check with your insurance carrier if you have a question of what your co-payment should be).

All health plans are not the same and do not cover the same services. In the event your health plan determines a service to be “not covered,” you will be responsible for the unpaid charge. A statement will be mailed to you for payment.

We will file an insurance claim for all services provided in the hospital.

If you have a question regarding a statement or a claim that was sent to your insurance company please call our Business Office at 469.800.6478.

Refilling a Prescription

If you need a prescription refill, please call your pharmacy. They will contact us with the appropriate information.

Here are some tips to help you keep up with your refills:

  • PLEASE DO NOT WAIT until you are out of medication before you call for a refill.
  • If you need a new prescription, please allow 48 hours from the time you make the request.
  • Please allow 5 working days for mail in prescriptions.

Medical Services

Baylor Scott & White Legacy Heart Center offers expertise and treatment options conveniently located near you.

  • Tests & Procedures
  • Coumadin Clinic
  • Pacemaker Clinic
  • Vein Clinic
  • Coronary Calcium Scoring

Coumadin Clinic

​​The Coumadin Clinic provides patients a convenient way to safely monitor their Coumadin levels.

Patients may schedule an appointment at the clinic for a face-to-face visit with specialized clinical staff or participate in a home monitoring system. We utilize machines that provide accurate results from a fingerstick within minutes. 

Pacemaker Clinic

Our pacemaker clinic evaluates and manages the care of patients prior to and following the implantation of cardiac pacemakers.

The frequency of a patient’s evaluation is determined by the patient’s needs, the age and type of pacing device, and the cardiologist’s recommendations. A typical schedule will include both clinical visits and remote/telephone monitoring. Telephone monitoring utilizes specifically designed transmitter units which allow the staff to analyze how well the pacemaker is working while the patient is at home.

The trained technician will review information from the device to check for function and battery life and make any adjustments recommended by the cardiologist.

Vein Clinic

Baylor Scott & White Legacy Heart Center Offers Minimally Invasive Treatment Options For Varicose Veins And Spider Veins.

Eliminate Varicose Veins Without Surgery​

Do You Experience Discomfort From Varicose Veins?
Our vein specialists offer effective solutions for treating varicose veins and spider ​​veins. We specialize in minimally invasive techniques that allow patients to be treated right in our office. 

What to Look for When Considering Treatment:

  • Veins that are dark purple or blue in color
  • Veins that appear twisted and bulging
  • An achy or heavy feeling in your legs
  • ​Burning, throbbing or muscle cramping in your legs
  • Swelling in your legs
  • Worsened pain after sitting or standing for a long time
  • Itching around one or more of your veins
  • Bleeding from varicose veins
  • Color changes, hardening of the vein, inflammation of the skin or skin ulcers near your ankle, which can mean you have a serious form of vascular disease that requires medical attention

Dramatic Results Without Drastic Measures
Banish varicose veins with a minimally invasive vein treatment that is safe and effective without ​lengthy downtime. It’s a non-surgical alternative to vein stripping that seals varicose veins shut and eliminates them for good.

Fast, Safe, In-office Procedures
Endovascular radiofrequency or laser ablation​
​During the procedure, a thin fiber is inserted into the varicose vein through a tiny entry point, usually near the knee. A local anesthetic is used to minimize the pain from the small incision. A local anesthetic is also applied along the length of the vein to make the procedure virtually painless. As the fiber is withdrawn, targeted energy damages the vein walls, shrinking them and closing the faulty vein so that blood cannot flow through it. The body simply reroutes the blood flow through healthier veins. No other tissue in the legs is affected.

For this procedure, your doctor injects small-sized varicose veins known as spider veins with a solution that closes those veins. Treated varicose veins should fade in a few weeks. Each vein can respond differently and may require an additional injection to achieve the desired result.


What are the complications of this procedure?
A small number of patients experience numbness that usually passes quickly. Also, there may be minor soreness and bruising. Any discomfort can be treated with over-the-counter, non-aspirin pain relievers as necessary.

How long does it take to recuperate?
Patients can expect a fast recovery. Usually a patient is up and walking immediately and can resume normal daily activity; however, patients are advised to avoid rigorous activities such as gym workouts for a few days. ​

Is this therapy effective for smaller varicose veins or spider veins? ​
After having minimally invasive vein treatment, you may still have smaller varicose veins and spider veins. Sclerotherapy can be used to treat these if desired.

Call 469.800.6300 to schedule a consultation with one of our vein specialists.

Coronary Calcium Scoring

What is Coronary Calcium Scoring? Coronary calcification has been shown to be a powerful risk indicator for heart disease.

A coronary calcium scoring is a simple, safe and quick way to “score” the amount of calcium in your heart. Studies have shown that coronary calcium scores directly correlate with the risk of heart attack, even if your other risk factors — family history, age, cholesterol levels, diabetes, smoking and obesity — are low. A higher coronary calcium score signals that plaque is present and atherosclerosis or hardening of the arteries has begun. The test is performed with a computed tomography (CT) scanner and takes about 15 minutes.

What are the risk factors?

According to the American Heart Association, the following are major contributing and other risk factors for heart disease:

  • High blood pressure
  • Diabetes
  • Family history of heart disease
  • Smoking
  • Inactive lifestyle
  • Obesity

It is important to remember that calcium scoring only estimates your risk of heart disease or a heart attack. Talk to our doctor to find out if coronary calcium scoring makes sense for you.

What should I expect at my CT scan?

A technologist will escort you into the scanning room, where you’ll see a table and a large, doughnut-shaped device called a gantry. The technologist will have you lie down on the padded table and make sure you’re comfortable. You’ll be asked to lie very still during the scan and hold your breath for a short time to minimize any body movement. During the scan, you might hear a humming noise but you will not feel anything unusual. The technologist can monitor you during the entire exam through a window and will talk to you through an intercom. The specific details of your upcoming examination will be explained fully by a technologist or your physician.

Are IVs or shots involved?

No, This procedure does not require injections, treadmills or other preparation such as fasting. However, it is a good idea to avoid caffeine 4-6 hours prior to your scan.

What should I expect after my scan?

The cardiologist will carefully analyze your images, review the findings with your physician and provide a report. Your physician will then discuss the results with you.

What does my score mean?

Scores can range from zero (low-risk) to 400 and above (high-risk). Scores indicate the extent of calcification in the heart’s coronary arteries, which indicates the presence of atherosclerosis or hardening of the arteries. Determining the extent of cardiac risk requires your doctor to interpret your calcium score in combination with other tests and risk factors.

Will my insurance cover the test?

Calcium scoring may not be covered by your insurance. Check with your insurance provider to see if your test will be covered.
