Telephone Medical Advice, Anytime

Medical advice is available whenever you need it. Please call our office. If you need medical advice after office hours, please call our main number and you will be connected to a member of our healthcare team.

After Hours Urgent Care

When our centers are closed, all CHA patients have access to urgent care services at several locations – CareWell (sites in Somerville and Cambridge) and Beth Israel Deaconess Urgent Care in Chelsea – where they will share their medical records with CHA. Urgent care is best for health problems that can’t wait for your doctor’s office to open and are not an emergency.

Call 911 for life-threatening emergencies. Remember, CHA has 24-hour emergency care at CHA Cambridge Hospital, CHA Somerville Hospital and CHA Everett Hospital.


As a national model and leader in interpreter services, we regularly provide support in more than 150 languages to all CHA sites. Interpreter services also handle requests for the deaf or hard of hearing, including American Sign Language and CDI services.
