What is the purpose of Box 5 on the CMS-1500?

Box 5 on the CMS-1500 form is specifically designated to capture the patient's address, which is crucial for communication purposes regarding the health insurance claim. Accurate details in this box help ensure that any correspondence related to the claim, such as requests for additional information, payment notifications, or other communications, reaches the patient in a timely manner. This information facilitates the claims process and enhances communication between the insurer and the patient.

The other options reflect different types of information that are not requested in Box 5. The box does not include surgical procedures, medical history, or emergency contact details—all of which may be documented elsewhere on the form or in other related medical records. Thus, the primary focus of Box 5 is to ensure that the patient’s address is correctly provided for efficient communication concerning the claim.
