What should a healthcare provider include in Block 33 to facilitate communication with insurers?

Including the provider's or supplier's billing name and telephone number in Block 33 is essential for effective communication with insurers. This information allows insurers to quickly identify the healthcare provider submitting the claim, which is critical for processing payments and resolving any questions about the claim. It serves as a point of contact for the insurer should they need to follow up regarding the claim, ask for additional information, or clarify details pertaining to billing or services rendered.

While the other options provide valuable information, they do not directly facilitate communication in the way that the provider's billing name and telephone number do. The National Provider Identifier (NPI) of the patient, the list of services rendered, and the date of the patient visit are important for the claim's content and validity but do not serve the same purpose for direct communication with insurance providers.
