Final answer:
The payer's Remittance Advice (RA) displays both the amount allowed for the provider as well as the patient's payment responsibilities, which includes copays and deductibles.
Step-by-step explanation:
The information displayed on the payer's Remittance Advice (RA) includes both the amount the provider is allowed by the payer (such as an insurance company) and the amount the patient is required to pay, such as the copay or deductible. This means the correct answer to the student's question is: d. Both the amount the provider is allowed and the amount the patient pays. The RA gives detailed information about claims after they have been processed, showing how the payment and patient responsibility amounts were determined based on the services provided and the insurance plan's coverage policies.
