FindMyDirectDoctor lists 3 anorectal surgery specialists in Massachusetts. We last checked this list in November 2026.
We confirmed board certification for 2 doctors on this list. Each profile shows the board and the specialty.
It depends on the practice. Many direct primary care and concierge practices charge a membership fee instead of billing insurance for office visits, and some also accept insurance. Each profile says how its practice works when the practice states it.
