Block 11 is used to store the insured's birth date and possibly gender; which block number is it?

• A. Block 11
• B. Block 12
• C. Block 9d
• D. Block 10

Answer: (A)

Block 11 on the CMS-1500 form is the space allocated for the insured’s birth date and gender. This placement ensures the policyholder’s demographic information is clearly linked to the insurance data, helping the payer verify identity and eligibility when processing the claim. Other blocks hold different kinds of information (such as patient demographics or details for other insureds), so they aren’t used for the insured’s birth date and sex. That’s why this is the correct block.
