Because of their philosophy, the terms are often mistakenly used interchangeably. In both cases patients contract directly with the physicians and receive more access to the provider. However, that’s where similarities end. In the case of DPC, the membership fee covers most or all physician services (more on that below). In the case of Concierge Medicine that may or may not be true. Such practices usually have higher “retainer” fees, may charge extra per visit, and may also bill your insurance. In general DPC practices try to bring quality care to the masses (or at least, one patient group at a time). On the opposite side of the spectrum, Concierge Medicine practices are often criticized as promoting a two-tiered health system that favors the wealthy.
