The principle behind the fraternal societies was simple. A group of working-class people would form an association (or join a local branch, or "lodge," of an existing association) and pay monthly fees into the association's treasury; individual members would then be able to draw on the pooled resources in time of need. The fraternal societies thus operated as a form of self-help insurance company.
Turn-of-the-century America offered a dizzying array of fraternal societies to choose from. Some catered to a particular ethnic or religious group; others did not. Many offered entertainment and social life to their members, or engaged in community service. Some "fraternal" societies were run entirely by and for women. The kinds of services from which members could choose often varied as well, though the most commonly offered were life insurance, disability insurance, and "lodge practice."
"Lodge practice" refers to an arrangement, reminiscent of today's HMOs, whereby a particular society or lodge would contract with a doctor to provide medical care to its members. The doctor received a regular salary on a retainer basis, rather than charging per item; members would pay a yearly fee and then call on the doctor's services as needed. If medical services were found unsatisfactory, the doctor would be penalized, and the contract might not be renewed. Lodge members reportedly enjoyed the degree of customer control this system afforded them. And the tendency to overuse the physician's services was kept in check by the fraternal society's own "self-policing"; lodge members who wanted to avoid future increases in premiums were motivated to make sure that their fellow members were not abusing the system.
Most remarkable was the low cost at which these medical services were provided. At the turn of the century, the average cost of "lodge practice" to an individual member was between one and two dollars a year. A day's wage would pay for a year's worth of medical care.
