If 11c is marked YES, which items must be completed?

• A. 9, 9a, and 9d
• B. 9, 9a, and 11
• C. 9b, 9c, and 9d
• D. 9, 10a, and 10d

Answer: (A)

When 11c is marked YES, it signals that there is other insurance involved and the claim needs information about that other insured. The CMS-1500 form handles this through the section for Other Insured Information, which is captured in the main field 9 and its subsections 9a and 9d. Those specific items collect the necessary details about the secondary payer so payments can be coordinated properly between insurers. Therefore, the required completed items are 9, 9a, and 9d. The other options involve fields that aren’t used for documenting the other insured information in this scenario, so they don’t fulfill the COB data requirement.
