Final answer:
Total patient cost is $168.75 for an ER visit after applying a $100 co-pay and 12.5% coinsurance on a remaining balance of $550 from a $650 bill.
Step-by-step explanation:
The total patient cost for the emergency room visit due to food poisoning, with a co-pay of $100 and 12.5% coinsurance on a $650 bill, is $181.25. Firstly, we apply the $100 fixed co-pay for the emergency room visit. After the co-pay, the remaining balance is $650 - $100 = $550. Next, the 12.5% coinsurance is applied to the remaining balance. The coinsurance amount is calculated as 12.5% of $550, which is 0.125 x $550 = $68.75. Adding the coinsurance to the co-pay gives us the total patient cost: $100 + $68.75 = $168.75.
According to the policy, the cost of an emergency room visit is a $100 copay plus 12.5% coinsurance. To find the coinsurance amount, we first calculate 12.5% of the total cost of the visit. Since the visit cost is $650, the coinsurance amount is 12.5% of $650, which is $81.25. Next, we add the copay and coinsurance to find the patient cost. The copay is $100 and the coinsurance is $81.25, so the patient cost is $100 + $81.25 = $181.25. Therefore, the patient cost of the emergency room visit is $181.25.
