What type of information is typically omitted from Block 33?

Block 33 of the CMS-1500 form is designated for the billing provider's information, specifically their name, address, and phone number. This block is essential for the insurance company to identify and contact the provider associated with the claim. The information in this block ensures that billing inquiries and payments are directed properly.

Typically, patient payment history does not belong on the CMS-1500 form, particularly in Block 33. Instead, this is private information that is usually kept in the provider's own records and is not necessary for claim processing. Therefore, omitting the patient's payment history from Block 33 is consistent with maintaining the focus on identifying the billing provider and facilitating the claims process without including irrelevant or personal information.
