Block 11 is where the insured's birth date goes, and it may include sex if different from Block 3.

• A. The insured's birth date and possibly sex
• B. The insured's death date
• C. The policy effective date
• D. The claim submission date

Answer: (A)

Block 11 is used to capture the insured’s demographic details, which are essential for linking the claim to the correct policy and preventing identity errors. The insured’s birth date serves as a key identifier, helping verify that the right person’s coverage is being billed. Including the insured’s sex in this block, if it differs from what’s recorded in Block 3, helps resolve any mismatch and ensures payer systems correctly match the claim to the insured record. The other options—death date, policy effective date, or claim submission date—aren’t fields designated for Block 11, so they wouldn’t be recorded there.
