Correct. Square is used to pay copays or balances that may remain after insurance payments have been processed (deductibles, denials, etc.). The main interface allows for the doctor to press one button to easily pay a known copay, or press another button to pay an arbitrary amount. In the screenshot here [1], the patient could pay his $490 balance by pressing the "Payment" button, or the $20 copay by pressing the "Copay" button.
