What does Block 9 of the Patient/Insured Section record?

• A. Information about any secondary insurance plan.
• B. Primary diagnosis code.
• C. The physician's signature.
• D. The date of service.

Answer: (A)

Block 9 in the Patient/Insured section is used to record information about any secondary insurance plan. When a patient has more than one insurer, the primary payer handles the claim first, and the secondary payer may cover remaining costs. Recording the secondary insurance details here supports coordination of benefits, ensuring the claim is billed to the right payer and payments are properly coordinated. If there isn’t a secondary policy, this block is typically left blank. Other items like the primary diagnosis code, physician’s signature, and date of service appear in different sections or blocks of the form.
