Which of the following is NOT a method of pre-registration for patients?

Pre-registration for patients typically involves processes that allow new patients to provide their information prior to their visit, helping streamline the check-in procedure and enhance efficiency in healthcare settings. Among the options given, in-person registration at the clinic is categorized as a method that occurs at the time of the visit rather than beforehand.

In contrast, mailing of new patient forms, online patient registration, and telephone call registrations constitute pre-registration methods as they involve actions taken by patients before arriving for their appointment. These methods focus on obtaining essential patient information, such as demographics and insurance information, ahead of time, which is beneficial for both the patient and the practice.

Therefore, in-person registration does not fit the definition of pre-registration, making it the answer that does not align with the methods that are used to prepare for a patient's visit prior to their arrival.
