Concierge medicine, also known as membership medicine, is an alternative practice model based on a relationship between a patient and a primary care physician in which the patient pays an annual fee or retainer. In exchange for the retainer, doctors provide enhanced care by limiting their patient panel to ensure direct availability and adequate time for each patient. Extended, unrushed visits enable physicians to spend meaningful time with patients, build relationships, and provide more comprehensive, proactive care than in traditional practices.
