Which information on an insurance card represents the routing and identification for a pharmacy claim?

The bank identification number is the correct choice as it specifically refers to the unique identifier used to process and route pharmacy claims through the financial infrastructure. This number is integral for managing transactions and is associated with the financial institution that the insurance company uses to process claims. It ensures that the claims are directed to the appropriate bank for reimbursement.

In the context of pharmacy claims, while the other options are important identifiers, they serve different purposes. The subscriber number typically identifies the individual covered by the insurance policy, while the group number connects an individual to their employer's insurance plan. The person code may designate dependents or other covered individuals. However, none of these options directly relate to the routing and transaction processing of the claim in the financial system as the bank identification number does.
