Massachusetts General Hospital Medical Walk-In Unit

Guided by the needs of its patients and their families, Massachusetts General Hospital (MGH or "Mass General") aims to deliver the very best health care in a safe, compassionate environment; to advance that care through innovative research and education; and to improve the health and wellbeing of the diverse communities it serves.

The third oldest general hospital in the United States and the oldest and largest hospital in New England, Mass General continues its tradition of excellence today. On July 17, 2012, Mass General was named America's best hospital by U. S. News & World Report based on quality of care, patient safety, and reputation in 16 different specialties.

MGH has a Medical Walk-In Unit.

The Medical Walk-In Unit offers another care option for patients (18 and over) who are unable to see their regular physician, are without a regular physician, or are visiting the Boston area. We recommend that you consult with your primary care provider about any health concerns before visiting the Medical Walk-In Unit. All patients of the Medical Walk-In Unit receive a comprehensive evaluation and treatment of non-life-threatening illnesses and injuries. Patients are seen on a first-come, first-served basis, with extremely urgent cases receiving priority attention.
