Which of the following is the least effective means of collecting patient fees?

Collecting patient fees through written communication is considered the least effective means for several reasons. First, written communication can lead to delays in payment because it relies on the patient receiving, understanding, and responding to a letter or email. Unlike immediate interactions, written requests may be ignored, misplaced, or delayed in the mail, making it less efficient for securing on-the-spot payment.

In contrast, requiring payment while the patient is in the office provides an immediate exchange, ensuring that payment is completed before the patient leaves. Contacting the patient by phone and verbal communication can also facilitate quicker responses, as both methods allow for direct dialogue and the opportunity to address any questions or concerns the patient may have at that moment. This immediacy and interaction greatly enhance the likelihood of successful fee collection. Thus, written communication lacks the urgency and personal engagement that characterize other methods, making it the least effective option for collecting patient fees.
