What is it?

The 6-in-6 diabetes program is a program that helps diabetics bring down their Hemoglobin A1c in the 6.0 range within 6 months. It is a well-known fact that management of diabetes requires a combination of medicines and lifestyle changes. The 6-in-6 diabetes program is revolutionary in that it succeeds where other programs fail. The structured program allows participants to understand how their bodies respond to various diets, exercises, and medications. This superior understanding enables better control. And better control makes it easy for participants to manage their disease and stay in the program longer.

Is it effective?

Since 2005, the program's participants have been able to meet or exceed the program's goals. And they have been able to keep their disease in control long after completing the program. Almost 80% of the programs participants were able to do so without medication. It is not at all unusual for patients to enroll while on insulin and within 3-6 months achieve levels of control that enable them to get off their insulin. We believe the program works because of its simplicity. And the program's unprecedented success rate is why we believe it is revolutionary.

How much does it cost?

Other than your insurance co-payments for every visit, the program itself is absolutely free. We do not charge patients separately for the program. If you have health insurance that we accept, then the only costs to you are your co-payments for every visit and any deductibles that your plan may impose. And patients without conventional health insurance can benefit from our direct-pay program, which is designed to ensure that this program benefits the maximum number of people.

Insurance plans

We accept insurance from most major insurance companies. If you are an existing patient, please inform our office of the any changes to your health plan, address, and/or phone number. If you are a new patient, then please call our office to check if we accept your health plan. Please bring all your health insurance cards each time you come to see us. If you have questions about whether we accept your insurance plan or about what paperwork you have to bring when you come in, please call our front desk at 703-404-5900.

Direct pay program

We have an affordable self-pay program for people without conventional insurance. We intentionally keep the rates low to make it affordable to the maximum number of people possible - including temporary overseas travelers visiting the USA.

For rates and other enquiries about the direct pay program, please contact our front desk at 703-404-5900.

Other information

For specific information about co-pay or deductions, please contact your human resources personnel or your insurance agent. We get asked about co-pay and deductions all the time. However, due to the large number of individualized insurance programs available, and the limited amount of information available to us, we seldom have up-to-date information on your policy coverage. Note that your human resources personnel or your insurance agent is the best resource to help you find this information before you arrive at our office.
