On the CMS-1500 claim form, which block is used to enter secondary insurance information such as AARP?

• A. Block 9
• B. Block 11
• C. Block 24A
• D. Block 32

Answer: (A)

The concept here is coordination of benefits: when there is a secondary payer, the form has a dedicated area to capture that other insurer’s information. The section labeled for Other Insured’s information is used to enter the secondary payer details, such as the policy or group number for entities like AARP. Filling this out lets the claim route to the secondary insurer after the primary payer processes it. The other areas of the form are for different data (dates of service, place of service, provider/facility details), so they aren’t used for reporting secondary insurance.
