High-quality weight loss surgery and care, close to home

- Laparoscopic and robot-assisted stomach bypass surgery
- Laparoscopic and robot assisted vertical sleeve gastrectomy
What is weight loss surgery?
Also known as bariatric surgery, weight loss surgery can help you lose weight by making your stomach smaller and/or changing the path of your intestine. It is usually only done if your body mas index (BMI) is at least 40 (or at least 35 and you have other weight-related health problems). If you are struggling with obesity and illnesses such as diabetes and sleep apnea, weight loss surgery may be right for you.
A team approach to long-term weight management
Surgery alone cannot cure obesity. To maintain long-term weight loss, you must permanently adjust your diet and lifestyle. That's why our team will make sure you have all the tools and knowledge you need to succeed—before, during and after surgery. Your core team will consist of a dietitian, a behavioral health specialist, a surgeon and a patient care coordinator - all working closely together to prepare you and your family for the procedure and required lifestyle changes. We will meet frequently in the months leading up to, and after, your surgery and then annually, or as needed, after the first year post-surgery. Peer support groups are an important part of our program. And, all patients are also registered in the MBSAQIP database so that long-term outcomes can be measured.

Is weight loss surgery effective?
Over 64 percent of American adults are overweight and roughly 15 million are obese. Over 300,000 Americans die each year as a result of obesity-related health conditions, such as diabetes, hypertension, sleep apnea and coronary artery disease.
Morbid obesity is defined as weighing more than 100 pounds over your ideal body weight for your height. For someone who is morbidly obese, weight loss surgery is the only treatment proven to result in long-term weight loss and the improvement or reversal or obesity-related health conditions.
People who choose weight loss surgery usually lose 50-70% of their excess body weight within two to five years of the procedure. Typically, obesity related illnesses such as diabetes and sleep apnea gradually start to resolve. In fact, many patients with Type 2 diabetes find that their blood sugars levels improve almost immediately after surgery and become completely normal within a year of surgery. Other improvements include
- Significant sustained weight loss
- Blood-sugar levels for patients with Type 2 diabetes that improve almost immediately and become completely normal within a year of surgery
- Lower blood pressure and total cholesterol
- Relief from sleep apnea and acid reflux
- Less osteoarthritis pain and improved mobility
- Improved mood and self-esteem
- Relief from urinary stress incontinence
- Decreased lower back pain
All surgical procedures have risks. Your surgeon will discuss potential risks with you in detail prior to your surgery date.
Some insurers consider weight loss surgery to be an elective procedure. Therefore, we must obtain insurance approval prior to scheduling your surgery. It is important to call your insurance company to make sure that you have bariatric benefits in your plan. Your insurer may ask you for the CPT code for the procedure. Please chose from the list below, depending on the type of weight loss surgery you intend to have.
- Laparoscopic Roux-en-Y gastric bypass: CPT CODE 43644
- Laparoscopic sleeve gastrectomy: CPT CODE 43775
While many of the costs incurred during the evaluation process will be covered by your insurance, some charges may become your responsibility. Due to program certification criteria, we are unable to accept patients who use Medicare as either their primary or secondary insurer.
If you qualify medically for surgery, the surgeon’s office will ask your insurer for pre-authorization of coverage for the procedure. Once we have received notification of pre-authorization from your insurer, a date for the operation will be scheduled. Once the surgery has been scheduled, you will be asked to come into the office about a week before the procedure to obtain informed consent.
We will work with you and your insurance to make sure that you meet their requirements. Some of these requirements are:
- History of failed weight loss attempts (such as physician-supervised weight loss, participation in commercial weight loss programs)
- Letter of medical necessity from your primary care physician
- Psychological evaluation (to make sure you have a clear understanding of how the surgery will impact your life and that you are committed to making permanent lifestyle changes)
- Nutrition evaluation (to identify dietary changes and habits that need to be changed in order to ensure a successful transition after weight loss surgery)
