Which block is specified as to be left blank?

• A. Block 2
• B. Block 7
• C. Block 4
• D. Block 9

Answer: (B)

The main idea here is that not every block on the CMS-1500 form must be filled. Some blocks are designated for information that isn’t required for standard claims, so they should be left blank to avoid confusion or processing errors. Block 7 is one of those blocks that is not used in typical submissions. It’s reserved for information that isn’t needed for most claims, so the instructions specify leaving it blank unless there’s a specific need to populate it. By not filling this field, you keep the claim clean and reduce chances of rejection or misinterpretation by payers or software. In practice, you complete the blocks that capture patient, provider, service, diagnosis, and billing details, and you leave unused blocks like this one empty. That’s why Block 7 is the correct choice.
