MIT Medical/Lexington

In 1999, MIT Medical opened a health care center in Lexington for members of the MIT community who live or work in the area, including employees of Lincoln Laboratory and the Whitehead Institute. Today, MIT Medical/Lexington offers primary care, pediatrics and several support services.

The staff at MIT Medical/Lexington takes a family-oriented approach to caring for patients. Since we see both adults and children in the same facility, our physicians and nurses bring their knowledge of family issues to the treatment of individual family members.

Specifically, we offer:

  • Primary Care
  • Pediatrics
  • Laboratory
  • Radiology: urgent X-rays at Beth Israel/Children's Hospital Medical Care Center in Lexington. Routine and specialized radiology services at MIT Medical in Cambridge.
  • Direct access to all the services at MIT/Medical Cambridge
  • Hospital care at MIT Medical's affiliated hospitals
  • Prescription drugs through four daily deliveries from the MIT Medical Pharmacy in Cambridge
  • Medical emergency response to Lincoln Laboratory employees during normal business hours.


All members of the MIT Traditional Health Plan for employees and members of the MIT Choice Plan who have MIT Medical PCPs can take advantage of all services at MIT Medical/Lexington. Other members of the MIT Choice Plan and other benefits-eligible employees may receive some services at MIT Medical/Lexington.
