Joslin Diabetes Center is a specialty hospital and research institute focused on diabetes care

Joslin Diabetes Center, located in Boston, Massachusetts, is an independent, nonprofit medical institution that treats people with all types of diabetes and conducts research into diabetes prevention and management. It operates as both a clinical care facility and a research organization affiliated with Harvard Medical School. Unlike a general endocrinology practice, Joslin functions as a comprehensive diabetes center where the entire medical team — doctors, nurses, dietitians, and mental health specialists — focuses specifically on diabetes rather than treating it as one condition among many.

The center sees patients in person at its Boston headquarters and through satellite locations in other states. It also offers remote consultations for people who cannot travel to Massachusetts. Joslin accepts most major insurance plans, though coverage and out-of-pocket costs vary by plan and by the specific services used.

Types of diabetes care Joslin provides

Joslin treats type 1 diabetes, type 2 diabetes, gestational diabetes, and other forms of diabetes. The center also sees people with prediabetes who want structured support to prevent progression to type 2 diabetes. Each patient works with an endocrinologist (a doctor who specializes in hormonal conditions, including diabetes) who manages blood sugar control and adjusts medications as needed.

Beyond medication management, Joslin offers diabetes education classes that teach how to use insulin, recognize low blood sugar, count carbohydrates, and adjust diet and activity. Registered dietitians work with patients to build eating plans that fit their daily life. Mental health counselors address the emotional weight of managing a chronic condition. Joslin also provides specialized services: certified diabetes educators, podiatrists for foot care, ophthalmologists for eye screening, and nephrologists for kidney health monitoring.

The center runs programs for specific populations, including adolescents, pregnant people with diabetes, and adults managing multiple complications. Joslin also operates a weight management program for people with type 2 diabetes.

How to schedule a first appointment

To schedule an appointment at Joslin, you can call their main line or use their online scheduling system on the Joslin website. You do not need a referral from your primary care doctor, though some insurance plans require prior authorization before your first visit. When you contact Joslin, staff will ask about your insurance and may verify coverage while you are on the phone.

New patients typically complete intake paperwork before their first visit, which includes your medical history, current medications, and diabetes history. If you are scheduling a remote visit, you will receive instructions on how to connect by video. If you are coming in person to Boston, Joslin is located near public transportation and has parking available.

Wait times for first appointments vary. During busy seasons, new patient appointments may be scheduled several weeks out. Established patients can usually book follow-up visits more quickly.

Insurance coverage and costs

Joslin accepts most major insurance plans, including Medicare, Medicaid (which varies by state), and commercial plans from major insurers. However, coverage details — such as copays, deductibles, and whether certain services require prior authorization — depend on your specific plan. Some plans cover all Joslin services in full after you meet your deductible; others require copays for each visit or service.

If you do not have insurance, Joslin has a financial information program for patients who meet income requirements. You can discuss payment options with Joslin's financial counselors when you call to schedule.

Telehealth visits (remote consultations) are typically covered by insurance at the same rate as in-person visits, though this varies by plan. Ask your insurance company or Joslin's billing department whether your plan covers remote appointments before your visit.

Joslin's research programs and clinical trials

Joslin Diabetes Center runs one of the largest diabetes research programs in the United States. The center conducts studies on new diabetes medications, insulin delivery systems, complications prevention, and lifestyle interventions. Some of these studies are open to patients receiving care at Joslin.

If you are interested in participating in a clinical trial, you can ask your Joslin doctor whether any active studies match your type of diabetes and health situation. Participation is always voluntary, and you can withdraw from a study at any time. Joslin's research team will explain what the study involves, any potential risks, and what you can expect.

Satellite locations and remote care options

Joslin's main facility is in Boston, but the center operates satellite clinics in other locations, including New York and Florida. These satellite locations offer many of the same services as the main campus, including endocrinology visits and diabetes education. However, not all specialized services are available at every location.

For patients who cannot travel to a Joslin location, remote consultations with endocrinologists and diabetes educators are available by video. Remote visits work best for routine follow-ups and medication adjustments. Some services — such as eye exams or foot assessments — may require an in-person visit or coordination with a local provider.

What to bring to your first appointment

Bring your insurance card and a photo ID. If you monitor your blood sugar at home, bring your meter and a record of recent readings, or read them from your device if it syncs to an app. Bring a list of all current medications, including doses and how often you take them. If you have records from previous diabetes care — such as lab results, past A1C tests, or notes from another endocrinologist — bring those as well.

If you use an insulin pump or continuous glucose monitor, bring that device or information about the model and settings. Write down any questions you want to ask during your visit so you do not forget them in the moment.
