Frequently asked questions
How is it possible for the program to be free?
All of our services are free of charge thanks to generous donations from The Leona M. and Harry B. Helmsley Charitable Trust, a philanthropy that is dedicated to improving the lives of people with T1D.
How do I know if I am eligible?
To sign up for Blue Circle Health, you must meet the following requirements:
- Be diagnosed with type 1 diabetes
- Be 18 years or older
- Eligible states: Florida, Ohio, Maine, Vermont, New Hampshire, Delaware, Alabama, Missouri, Mississippi, and Iowa
- Speak English and/or Spanish
- Have access to the internet and a smart phone or computer to do video calls with the care team
- Have a primary care provider or are willing to be connected to one
- Are not currently pregnant
What if I have an endocrinologist already?
Great! Our program is designed to provide extra support beyond what’s typically available via clinics. If you have great endocrinology care, we’ll spend our time together supporting you in other ways (e.g., with insurance, additional education, connecting you to a community of folks with T1D, etc.). We will keep your existing care team posted on your progress and coordinate any additional care needed with them.
How does the program work?
The program is virtual, meaning we use text, phone calls, and video meetings (e.g., Zoom) to communicate with you. It’s designed to last up to 6 months and our goal during that time is to provide you with the care, education, and supplies you need to thrive with this difficult disease.
It starts with us asking you questions to learn what areas you could use a hand with. Some people just need a quick brush up on managing highs or lows. Others need to see our endocrinologist, need help getting insurance or affording their insulin, or might benefit from being connected to housing or employment agencies in order to better manage their disease. Everyone’s journey with T1D is different and we design our program to meet your needs.
We use the term “Full Circle” to describe patients who have completed our program, and invite them to continue to meet with us monthly to stay connected to our growing community.
What is a T1D support guide?
One of the first people you’ll meet when you sign up for Blue Circle Health is your T1D Support Guide. Our support guides also live with T1D and act as your personal guide throughout your time at Blue Circle Health. They’re someone to talk (or text) with when you’re having a tough day and they can work with you and your care team to be sure you’re getting the support you need while you’re part of the program.
What kind of things does Blue Circle Health help with?
Our program has a whole team of T1D specialists, many of whom live with T1D. This includes certified diabetes educators, T1D support guides, insurance specialists, social workers, nurses, and doctors – all dedicated to helping you thrive with T1D.
We can help you understand and manage your blood sugars, learn more about different insulin options and devices, help with insurance issues, connect you to local resources, and even prescribe needed drugs and devices. We have a patient assistance program for patients that can’t afford their T1D-related medications and supplies and a Continuous Glucose Monitor (CGM) trial program for people that want to try managing their T1D with the aid of a CGM.
