Which box is used to fill in the patient's address?

The box that is designated for the patient's address on the CMS-1500 form is Box 5. This box is specifically meant for inputting the patient's address, ensuring that claims are processed accurately and can be sent or associated correctly with the patient's demographic information. Properly filling out this part of the form is crucial for communication and follow-up regarding the claim, as it serves as a direct way to identify and reach the patient if necessary.

While other boxes on the CMS-1500 have distinct purposes, such as identifying the patient (Box 3) or the insured's information (Box 6), it is Box 5 that is focused solely on the patient's address. Understanding the significance of accurately completing Box 5 helps in ensuring that claims-related correspondence reaches the correct individual.
