According to a survey conducted by OBG Management, October 1994, CIRCUMCISION: A SURVEY OF FEES AND PRACTICES,
Ob-Gyns' fees for circumcision range from $0 to $400, averaging $137 nationwide, according to an OBG Management survey of more than 200 physicians. The survey found that fees are highest in New Jersey ($237.50, on average), New York, Maryland and other Atlantic seaboard states. By contrast, several physicians in the Midwest, Deep South and Southwest changed $50 to 75.
