Which block indicates whether employment, auto liability, or other accident involvement applies to services in block 24?

• A. Block 9a
• B. Block 9d
• C. Block 11a
• D. Block 10c

Answer: (B)

The key idea is where the form signals that a claim is tied to an accident and who is liable. Block 24 lists the services being billed, but the accident/liability status for those services is captured in Block 9d. This subfield is used to indicate if the claim involves an auto accident, employment/workers’ comp, or other liability, guiding how the claim is processed and which payer is responsible. If that accident information isn’t noted in this field, the claim could be treated as a straightforward health insurance claim rather than being routed to the correct liability insurer. Other parts of Block 9 contain details about other insureds (policy numbers, dates of birth, or employer information), which do not specify the accident involvement. So Block 9d is the designated place for signaling the accident-related liability affecting the services listed in Block 24.
