A doctor's visit, also known as "doctor's office visit" or "physician office visit", is a meeting between a patient with a physician to get health advice or treatment for a symptom or condition. According to a survey in the United States, a physician typically sees between 50 and 100 patients per week, but it may vary with medical specialty, but differs only little by community size such as metropolitan versus rural areas.

The four great cornerstones of diagnostic medicine are anatomy (structure: what is there), physiology (how the structure/s work), pathology (what goes wrong with the anatomy and physiology) and psychology (mind and behavior). In addition, the physician should consider the patient in their 'well' context rather than simply as a walking medical condition. This means the socio-political context of the patient (family, work, stress, beliefs) should be assessed as it often offers vital clues to the patient's condition and further management.

A patient typically presents a set of complaints (the symptoms) to the physician, who then performs a diagnostic procedure, which generally includes obtaining further information about the patient's symptoms, previous state of health, living conditions, and so forth. The physician then makes a review of systems (ROS) or systems inquiry, which is a set of ordered questions about each major body system in order: general (such as weight loss), endocrine, cardio-respiratory, etc. Next comes the actual physical examination and other medical tests; the findings are recorded, leading to a list of possible diagnoses. These will be investigated in order of probability.
