Which block records information about any secondary insurance plan?

• A. Block 3
• B. Block 9
• C. Block 14
• D. Block 7a

Answer: (B)

Coordinating benefits when more than one payer is involved requires a specific place on the claim to capture secondary coverage. On the standard claim form, the field designated for information about any other insured plan is Block 9. Entering the secondary insurer’s policy or group information there keeps the data organized for COB processing, so the secondary payer can be billed after the primary has paid. Other blocks hold data related to the patient or the primary insured, not the secondary plan, so this block is the correct location for secondary insurance details.
