Remittance code mapping can be done at the plan, ____________, or service area level.

• A. patient
• B. facility
• C. payer group
• D. payer

Answer: (D)

Remittance code mapping is applied at different scopes to ensure consistent interpretation of remittance advice across claims. The levels commonly used include plan, payer, and service area. Filling the blank with the payer makes sense because it represents a payer-wide scope that covers all plans under that payer and across service areas, providing uniform mapping rules. Mapping at the payer level is broader than plan-specific rules and generalizes across multiple service areas, which is why it’s the best fit among the options. The other choices are too granular or not standard mapping scopes in this context (patient and facility are individual or site-specific, and payer group isn’t the level referenced here).
