Select the correct entry for the name of a provider on the CMS-1500 claim.

The entry for the name of a provider on the CMS-1500 claim should follow specific formatting guidelines to ensure clarity and standardization. In this context, the correct choice, "MARY SMITH MD," adheres to the requirement of presenting the provider's name in a straightforward manner, without any punctuation or additional titles.

Using "MARY SMITH MD" combines the provider's full name followed by their professional designation without the use of a comma or any other additional formatting elements, which aligns with the CMS-1500 guidelines for claim submission. It's essential for providers’ names to be listed clearly to avoid any confusion during the claims processing stage.

In contrast, other options that incorporate different formats, such as the addition of a comma or the title "DR." at the beginning, don't comply with these standards, making them less suitable for accurate claim submission. Hence, "MARY SMITH MD" is the preferred format for clarity and compliance with billing practices.
