A patient has met a Medicare deductible of $150. The patient's coinsurance is 20% and the allowed amount is $600. What is the patient's out-of-pocket expense?

To determine the patient's out-of-pocket expense in this scenario, we begin by considering the Medicare deductible and coinsurance.

The patient has already met the deductible of $150, so this amount will not be deducted from the allowed amount again. The allowed amount for the service performed is $600.

After the deductible is met, the patient's responsibility includes the coinsurance, which is 20% of the allowed amount. To calculate this, we first determine 20% of $600:

20% of $600 equals $120 (calculated as $600 x 0.20).

Since the patient has already satisfied the deductible, their out-of-pocket expense will be based solely on the 20% coinsurance amount of $120.

Thus, the patient's total out-of-pocket expense is the coinsurance of $120. This sum reflects the calculated share of costs for the service after the deductible has been met, making it the right answer in this case.
