Final answer:
The discount amount is $160, the carrier payment is $217, and the write-off amount is $160. These are calculated based on the difference between the total charges and the allowed amount. Option a.
Step-by-step explanation:
The question involves calculating the discount amount, carrier payment, and the write-off amount for a medical service. The total charge for the service was $377, but the allowed amount for the service is $217. Therefore, the discount amount is the difference between the total charged and the allowed amount, which is $377 - $217 = $160. The carrier will pay the allowed amount of $217. The write-off amount is typically the same as the discount amount, as it represents the portion of the charge that the medical provider agrees not to collect, which is $160. Option a.
